+/**
+ * @ngdoc service
+ * @name $animateCss
+ * @kind object
+ *
+ * @description
+ * The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
+ * from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
+ * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
+ * directives to create more complex animations that can be purely driven using CSS code.
+ *
+ * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
+ * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
+ *
+ * ## Usage
+ * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
+ * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
+ * any automatic control over cancelling animations and/or preventing animations from being run on
+ * child elements will not be handled by Angular. For this to work as expected, please use `$animate` to
+ * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
+ * the CSS animation.
+ *
+ * The example below shows how we can create a folding animation on an element using `ng-if`:
+ *
+ * ```html
+ * <!-- notice the `fold-animation` CSS class -->
+ * <div ng-if="onOff" class="fold-animation">
+ * This element will go BOOM
+ * </div>
+ * <button ng-click="onOff=true">Fold In</button>
+ * ```
+ *
+ * Now we create the **JavaScript animation** that will trigger the CSS transition:
+ *
+ * ```js
+ * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
+ * return {
+ * enter: function(element, doneFn) {
+ * var height = element[0].offsetHeight;
+ * return $animateCss(element, {
+ * from: { height:'0px' },
+ * to: { height:height + 'px' },
+ * duration: 1 // one second
+ * });
+ * }
+ * }
+ * }]);
+ * ```
+ *
+ * ## More Advanced Uses
+ *
+ * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
+ * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
+ *
+ * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
+ * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
+ * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
+ * to provide a working animation that will run in CSS.
+ *
+ * The example below showcases a more advanced version of the `.fold-animation` from the example above:
+ *
+ * ```js
+ * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
+ * return {
+ * enter: function(element, doneFn) {
+ * var height = element[0].offsetHeight;
+ * return $animateCss(element, {
+ * addClass: 'red large-text pulse-twice',
+ * easing: 'ease-out',
+ * from: { height:'0px' },
+ * to: { height:height + 'px' },
+ * duration: 1 // one second
+ * });
+ * }
+ * }
+ * }]);
+ * ```
+ *
+ * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
+ *
+ * ```css
+ * /* since a hardcoded duration value of 1 was provided in the JavaScript animation code,
+ * the CSS classes below will be transitioned despite them being defined as regular CSS classes */
+ * .red { background:red; }
+ * .large-text { font-size:20px; }
+ *
+ * /* we can also use a keyframe animation and $animateCss will make it work alongside the transition */
+ * .pulse-twice {
+ * animation: 0.5s pulse linear 2;
+ * -webkit-animation: 0.5s pulse linear 2;
+ * }
+ *
+ * @keyframes pulse {
+ * from { transform: scale(0.5); }
+ * to { transform: scale(1.5); }
+ * }
+ *
+ * @-webkit-keyframes pulse {
+ * from { -webkit-transform: scale(0.5); }
+ * to { -webkit-transform: scale(1.5); }
+ * }
+ * ```
+ *
+ * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
+ *
+ * ## How the Options are handled
+ *
+ * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
+ * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline
+ * styles using the `from` and `to` properties.
+ *
+ * ```js
+ * var animator = $animateCss(element, {
+ * from: { background:'red' },
+ * to: { background:'blue' }
+ * });
+ * animator.start();
+ * ```
+ *
+ * ```css
+ * .rotating-animation {
+ * animation:0.5s rotate linear;
+ * -webkit-animation:0.5s rotate linear;
+ * }
+ *
+ * @keyframes rotate {
+ * from { transform: rotate(0deg); }
+ * to { transform: rotate(360deg); }
+ * }
+ *
+ * @-webkit-keyframes rotate {
+ * from { -webkit-transform: rotate(0deg); }
+ * to { -webkit-transform: rotate(360deg); }
+ * }
+ * ```
+ *
+ * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
+ * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
+ * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
+ * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
+ * and spread across the transition and keyframe animation.
+ *
+ * ## What is returned
+ *
+ * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
+ * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
+ * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
+ *
+ * ```js
+ * var animator = $animateCss(element, { ... });
+ * ```
+ *
+ * Now what do the contents of our `animator` variable look like:
+ *
+ * ```js
+ * {
+ * // starts the animation
+ * start: Function,
+ *
+ * // ends (aborts) the animation
+ * end: Function
+ * }
+ * ```
+ *
+ * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends.
+ * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and styles may have been
+ * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
+ * and that changing them will not reconfigure the parameters of the animation.
+ *
+ * ### runner.done() vs runner.then()
+ * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the
+ * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
+ * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
+ * unless you really need a digest to kick off afterwards.
+ *
+ * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
+ * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
+ * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
+ *
+ * @param {DOMElement} element the element that will be animated
+ * @param {object} options the animation-related options that will be applied during the animation
+ *
+ * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied
+ * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.)
+ * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and
+ * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted.
+ * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
+ * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`).
+ * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
+ * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
+ * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
+ * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
+ * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
+ * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0`
+ * is provided then the animation will be skipped entirely.
+ * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is
+ * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value
+ * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same
+ * CSS delay value.
+ * * `stagger` - A numeric time value representing the delay between successively animated elements
+ * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
+ * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a
+ * `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
+ * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occurring on the classes being added and removed.)
+ * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once
+ * the animation is closed. This is useful for when the styles are used purely for the sake of
+ * the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation).
+ * By default this value is set to `false`.
+ *
+ * @return {object} an object with start and end methods and details about the animation.
+ *
+ * * `start` - The method to start the animation. This will return a `Promise` when called.
+ * * `end` - This method will cancel the animation and remove all applied CSS classes and styles.

+/**
+ * @ngdoc module
+ * @name ngAnimate
+ * @description
+ *
+ * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
+ * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an Angular app.
+ *
+ * <div doc-module-components="ngAnimate"></div>
+ *
+ * # Usage
+ * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based
+ * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
+ * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
+ * the HTML element that the animation will be triggered on.
+ *
+ * ## Directive Support
+ * The following directives are "animation aware":
+ *
+ * | Directive | Supported Animations |
+ * |----------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------|
+ * | {@link ng.directive:ngRepeat#animations ngRepeat} | enter, leave and move |
+ * | {@link ngRoute.directive:ngView#animations ngView} | enter and leave |
+ * | {@link ng.directive:ngInclude#animations ngInclude} | enter and leave |
+ * | {@link ng.directive:ngSwitch#animations ngSwitch} | enter and leave |
+ * | {@link ng.directive:ngIf#animations ngIf} | enter and leave |
+ * | {@link ng.directive:ngClass#animations ngClass} | add and remove (the CSS class(es) present) |
+ * | {@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide} | add and remove (the ng-hide class value) |
+ * | {@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel} | add and remove (dirty, pristine, valid, invalid & all other validations) |
+ * | {@link module:ngMessages#animations ngMessages} | add and remove (ng-active & ng-inactive) |
+ * | {@link module:ngMessages#animations ngMessage} | enter and leave |
+ *
+ * (More information can be found by visiting each the documentation associated with each directive.)
+ *
+ * ## CSS-based Animations
+ *
+ * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML
+ * and CSS code we can create an animation that will be picked up by Angular when an the underlying directive performs an operation.
+ *
+ * The example below shows how an `enter` animation can be made possible on an element using `ng-if`:
+ *
+ * ```html
+ * <div ng-if="bool" class="fade">
+ * Fade me in out
+ * </div>
+ * <button ng-click="bool=true">Fade In!</button>
+ * <button ng-click="bool=false">Fade Out!</button>
+ * ```
+ *
+ * Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
+ *
+ * ```css
+ * /* The starting CSS styles for the enter animation */
+ * .fade.ng-enter {
+ * transition:0.5s linear all;
+ * opacity:0;
+ * }
+ *
+ * /* The finishing CSS styles for the enter animation */
+ * .fade.ng-enter.ng-enter-active {
+ * opacity:1;
+ * }
+ * ```
+ *
+ * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two
+ * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition
+ * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
+ *
+ * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions:
+ *
+ * ```css
+ * /* now the element will fade out before it is removed from the DOM */
+ * .fade.ng-leave {
+ * transition:0.5s linear all;
+ * opacity:1;
+ * }
+ * .fade.ng-leave.ng-leave-active {
+ * opacity:0;
+ * }
+ * ```
+ *
+ * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
+ *
+ * ```css
+ * /* there is no need to define anything inside of the destination
+ * CSS class since the keyframe will take charge of the animation */
+ * .fade.ng-leave {
+ * animation: my_fade_animation 0.5s linear;
+ * -webkit-animation: my_fade_animation 0.5s linear;
+ * }
+ *
+ * @keyframes my_fade_animation {
+ * from { opacity:1; }
+ * to { opacity:0; }
+ * }
+ *
+ * @-webkit-keyframes my_fade_animation {
+ * from { opacity:1; }
+ * to { opacity:0; }
+ * }
+ * ```
+ *
+ * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
+ *
+ * ### CSS Class-based Animations
+ *
+ * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
+ * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
+ * and removed.
+ *
+ * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
+ *
+ * ```html
+ * <div ng-show="bool" class="fade">
+ * Show and hide me
+ * </div>
+ * <button ng-click="bool=!bool">Toggle</button>
+ *
+ * <style>
+ * .fade.ng-hide {
+ * transition:0.5s linear all;
+ * opacity:0;
+ * }
+ * </style>
+ * ```
+ *
+ * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since
+ * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
+ *
+ * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation
+ * with CSS styles.
+ *
+ * ```html
+ * <div ng-class="{on:onOff}" class="highlight">
+ * Highlight this box
+ * </div>
+ * <button ng-click="onOff=!onOff">Toggle</button>
+ *
+ * <style>
+ * .highlight {
+ * transition:0.5s linear all;
+ * }
+ * .highlight.on-add {
+ * background:white;
+ * }
+ * .highlight.on {
+ * background:yellow;
+ * }
+ * .highlight.on-remove {
+ * background:black;
+ * }
+ * </style>
+ * ```
+ *
+ * We can also make use of CSS keyframes by placing them within the CSS classes.
+ *
+ *
+ * ### CSS Staggering Animations
+ * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
+ * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be
+ * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
+ * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
+ * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
+ *
+ * ```css
+ * .my-animation.ng-enter {
+ * /* standard transition code */
+ * transition: 1s linear all;
+ * opacity:0;
+ * }
+ * .my-animation.ng-enter-stagger {
+ * /* this will have a 100ms delay between each successive leave animation */
+ * transition-delay: 0.1s;
+ *
+ * /* As of 1.4.4, this must always be set: it signals ngAnimate
+ * to not accidentally inherit a delay property from another CSS class */
+ * transition-duration: 0s;
+ * }
+ * .my-animation.ng-enter.ng-enter-active {
+ * /* standard transition styles */
+ * opacity:1;
+ * }
+ * ```
+ *
+ * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
+ * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
+ * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
+ * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired.
+ *
+ * The following code will issue the **ng-leave-stagger** event on the element provided:
+ *
+ * ```js
+ * var kids = parent.children();
+ *
+ * $animate.leave(kids[0]); //stagger index=0
+ * $animate.leave(kids[1]); //stagger index=1
+ * $animate.leave(kids[2]); //stagger index=2
+ * $animate.leave(kids[3]); //stagger index=3
+ * $animate.leave(kids[4]); //stagger index=4
+ *
+ * window.requestAnimationFrame(function() {
+ * //stagger has reset itself
+ * $animate.leave(kids[5]); //stagger index=0
+ * $animate.leave(kids[6]); //stagger index=1
+ *
+ * $scope.$digest();
+ * });
+ * ```
+ *
+ * Stagger animations are currently only supported within CSS-defined animations.
+ *
+ * ### The `ng-animate` CSS class
+ *
+ * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
+ * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
+ *
+ * Therefore, animations can be applied to an element using this temporary class directly via CSS.
+ *
+ * ```css
+ * .zipper.ng-animate {
+ * transition:0.5s linear all;
+ * }
+ * .zipper.ng-enter {
+ * opacity:0;
+ * }
+ * .zipper.ng-enter.ng-enter-active {
+ * opacity:1;
+ * }
+ * .zipper.ng-leave {
+ * opacity:1;
+ * }
+ * .zipper.ng-leave.ng-leave-active {
+ * opacity:0;
+ * }
+ * ```
+ *
+ * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
+ * the CSS class once an animation has completed.)
+ *
+ *
+ * ### The `ng-[event]-prepare` class
+ *
+ * This is a special class that can be used to prevent unwanted flickering / flash of content before
+ * the actual animation starts. The class is added as soon as an animation is initialized, but removed
+ * before the actual animation starts (after waiting for a $digest).
+ * It is also only added for *structural* animations (`enter`, `move`, and `leave`).
+ *
+ * In practice, flickering can appear when nesting elements with structural animations such as `ngIf`
+ * into elements that have class-based animations such as `ngClass`.
+ *
+ * ```html
+ * <div ng-class="{red: myProp}">
+ * <div ng-class="{blue: myProp}">
+ * <div class="message" ng-if="myProp"></div>
+ * </div>
+ * </div>
+ * ```
+ *
+ * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating.
+ * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts:
+ *
+ * ```css
+ * .message.ng-enter-prepare {
+ * opacity: 0;
+ * }
+ *
+ * ```
+ *
+ * ## JavaScript-based Animations
+ *
+ * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
+ * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the
+ * `module.animation()` module function we can register the animation.
+ *
+ * Let's see an example of a enter/leave animation using `ngRepeat`:
+ *
+ * ```html
+ * <div ng-repeat="item in items" class="slide">
+ * {{ item }}
+ * </div>
+ * ```
+ *
+ * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`:
+ *
+ * ```js
+ * myModule.animation('.slide', [function() {
+ * return {
+ * // make note that other events (like addClass/removeClass)
+ * // have different function input parameters
+ * enter: function(element, doneFn) {
+ * jQuery(element).fadeIn(1000, doneFn);
+ *
+ * // remember to call doneFn so that angular
+ * // knows that the animation has concluded
+ * },
+ *
+ * move: function(element, doneFn) {
+ * jQuery(element).fadeIn(1000, doneFn);
+ * },
+ *
+ * leave: function(element, doneFn) {
+ * jQuery(element).fadeOut(1000, doneFn);
+ * }
+ * }
+ * }]);
+ * ```
+ *
+ * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as
+ * greensock.js and velocity.js.
+ *
+ * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define
+ * our animations inside of the same registered animation, however, the function input arguments are a bit different:
+ *
+ * ```html
+ * <div ng-class="color" class="colorful">
+ * this box is moody
+ * </div>
+ * <button ng-click="color='red'">Change to red</button>
+ * <button ng-click="color='blue'">Change to blue</button>
+ * <button ng-click="color='green'">Change to green</button>
+ * ```
+ *
+ * ```js
+ * myModule.animation('.colorful', [function() {
+ * return {
+ * addClass: function(element, className, doneFn) {
+ * // do some cool animation and call the doneFn
+ * },
+ * removeClass: function(element, className, doneFn) {
+ * // do some cool animation and call the doneFn
+ * },
+ * setClass: function(element, addedClass, removedClass, doneFn) {
+ * // do some cool animation and call the doneFn
+ * }
+ * }
+ * }]);
+ * ```
+ *
+ * ## CSS + JS Animations Together
+ *
+ * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of Angular,
+ * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking
+ * charge of the animation**:
+ *
+ * ```html
+ * <div ng-if="bool" class="slide">
+ * Slide in and out
+ * </div>
+ * ```
+ *
+ * ```js
+ * myModule.animation('.slide', [function() {
+ * return {
+ * enter: function(element, doneFn) {
+ * jQuery(element).slideIn(1000, doneFn);
+ * }
+ * }
+ * }]);
+ * ```
+ *
+ * ```css
+ * .slide.ng-enter {
+ * transition:0.5s linear all;
+ * transform:translateY(-100px);
+ * }
+ * .slide.ng-enter.ng-enter-active {
+ * transform:translateY(0);
+ * }
+ * ```
+ *
+ * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the
+ * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
+ * our own JS-based animation code:
+ *
+ * ```js
+ * myModule.animation('.slide', ['$animateCss', function($animateCss) {
+ * return {
+ * enter: function(element) {
+* // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
+ * return $animateCss(element, {
+ * event: 'enter',
+ * structural: true
+ * });
+ * }
+ * }
+ * }]);
+ * ```
+ *
+ * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
+ *
+ * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or
+ * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that
+ * data into `$animateCss` directly:
+ *
+ * ```js
+ * myModule.animation('.slide', ['$animateCss', function($animateCss) {
+ * return {
+ * enter: function(element) {
+ * return $animateCss(element, {
+ * event: 'enter',
+ * structural: true,
+ * addClass: 'maroon-setting',
+ * from: { height:0 },
+ * to: { height: 200 }
+ * });
+ * }
+ * }
+ * }]);
+ * ```
+ *
+ * Now we can fill in the rest via our transition CSS code:
+ *
+ * ```css
+ * /* the transition tells ngAnimate to make the animation happen */
+ * .slide.ng-enter { transition:0.5s linear all; }
+ *
+ * /* this extra CSS class will be absorbed into the transition
+ * since the $animateCss code is adding the class */
+ * .maroon-setting { background:red; }
+ * ```
+ *
+ * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over.
+ *
+ * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}.
+ *
+ * ## Animation Anchoring (via `ng-animate-ref`)
+ *
+ * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
+ * structural areas of an application (like views) by pairing up elements using an attribute
+ * called `ng-animate-ref`.
+ *
+ * Let's say for example we have two views that are managed by `ng-view` and we want to show
+ * that there is a relationship between two components situated in within these views. By using the
+ * `ng-animate-ref` attribute we can identify that the two components are paired together and we
+ * can then attach an animation, which is triggered when the view changes.
+ *
+ * Say for example we have the following template code:
+ *
+ * ```html
+ * <!-- index.html -->
+ * <div ng-view class="view-animation">
+ * </div>
+ *
+ * <!-- home.html -->
+ * <a href="#/banner-page">
+ * <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
+ * </a>
+ *
+ * <!-- banner-page.html -->
+ * <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
+ * ```
+ *
+ * Now, when the view changes (once the link is clicked), ngAnimate will examine the
+ * HTML contents to see if there is a match reference between any components in the view
+ * that is leaving and the view that is entering. It will scan both the view which is being
+ * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
+ * contain a matching ref value.
+ *
+ * The two images match since they share the same ref value. ngAnimate will now create a
+ * transport element (which is a clone of the first image element) and it will then attempt
+ * to animate to the position of the second image element in the next view. For the animation to
+ * work a special CSS class called `ng-anchor` will be added to the transported element.
+ *
+ * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
+ * ngAnimate will handle the entire transition for us as well as the addition and removal of
+ * any changes of CSS classes between the elements:
+ *
+ * ```css
+ * .banner.ng-anchor {
+ * /* this animation will last for 1 second since there are
+ * two phases to the animation (an `in` and an `out` phase) */
+ * transition:0.5s linear all;
+ * }
+ * ```
+ *
+ * We also **must** include animations for the views that are being entered and removed
+ * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
+ *
+ * ```css
+ * .view-animation.ng-enter, .view-animation.ng-leave {
+ * transition:0.5s linear all;
+ * position:fixed;
+ * left:0;
+ * top:0;
+ * width:100%;
+ * }
+ * .view-animation.ng-enter {
+ * transform:translateX(100%);
+ * }
+ * .view-animation.ng-leave,
+ * .view-animation.ng-enter.ng-enter-active {
+ * transform:translateX(0%);
+ * }
+ * .view-animation.ng-leave.ng-leave-active {
+ * transform:translateX(-100%);
+ * }
+ * ```
+ *
+ * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
+ * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
+ * from its origin. Once that animation is over then the `in` stage occurs which animates the
+ * element to its destination. The reason why there are two animations is to give enough time
+ * for the enter animation on the new element to be ready.
+ *
+ * The example above sets up a transition for both the in and out phases, but we can also target the out or
+ * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
+ *
+ * ```css
+ * .banner.ng-anchor-out {
+ * transition: 0.5s linear all;
+ *
+ * /* the scale will be applied during the out animation,
+ * but will be animated away when the in animation runs */
+ * transform: scale(1.2);
+ * }
+ *
+ * .banner.ng-anchor-in {
+ * transition: 1s linear all;
+ * }
+ * ```
+ *

+ *
+ * ### How is the element transported?
+ *
+ * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
+ * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
+ * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
+ * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
+ * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
+ * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
+ * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
+ * will become visible since the shim class will be removed.
+ *
+ * ### How is the morphing handled?
+ *
+ * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
+ * what CSS classes differ between the starting element and the destination element. These different CSS classes
+ * will be added/removed on the anchor element and a transition will be applied (the transition that is provided
+ * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
+ * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
+ * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
+ * the cloned element is placed inside of root element which is likely close to the body element).
+ *
+ * Note that if the root element is on the `<html>` element then the cloned node will be placed inside of body.
+ *
+ *
+ * ## Using $animate in your directive code
+ *
+ * So far we've explored how to feed in animations into an Angular application, but how do we trigger animations within our own directives in our application?
+ * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
+ * imagine we have a greeting box that shows and hides itself when the data changes
+ *
+ * ```html
+ * <greeting-box active="onOrOff">Hi there</greeting-box>
+ * ```
+ *
+ * ```js
+ * ngModule.directive('greetingBox', ['$animate', function($animate) {
+ * return function(scope, element, attrs) {
+ * attrs.$observe('active', function(value) {
+ * value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
+ * });
+ * });
+ * }]);
+ * ```
+ *
+ * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
+ * in our HTML code then we can trigger a CSS or JS animation to happen.
+ *
+ * ```css
+ * /* normally we would create a CSS class to reference on the element */
+ * greeting-box.on { transition:0.5s linear all; background:green; color:white; }
+ * ```
+ *
+ * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
+ * possible be sure to visit the {@link ng.$animate $animate service API page}.
+ *
+ *
+ * ## Callbacks and Promises
+ *
+ * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
+ * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
+ * ended by chaining onto the returned promise that animation method returns.
+ *
+ * ```js
+ * // somewhere within the depths of the directive
+ * $animate.enter(element, parent).then(function() {
+ * //the animation has completed
+ * });
+ * ```
+ *
+ * (Note that earlier versions of Angular prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
+ * anymore.)
+ *
+ * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
+ * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
+ * routing controller to hook into that:
+ *
+ * ```js
+ * ngModule.controller('HomePageController', ['$animate', function($animate) {
+ * $animate.on('enter', ngViewElement, function(element) {
+ * // the animation for this route has completed
+ * }]);
+ * }])
+ * ```
+ *
+ * (Note that you will need to trigger a digest within the callback to get angular to notice any scope-related changes.)

+ * The returned resource object has action methods which provide high-level behaviors without
+ * the need to interact with the low level {@link ng.$http $http} service.
+ *
+ * Requires the {@link ngResource `ngResource`} module to be installed.
+ *
+ * By default, trailing slashes will be stripped from the calculated URLs,

+ * this:
+ *
+ * ```js

+ // Don't strip trailing slashes from calculated URLs
+ $resourceProvider.defaults.stripTrailingSlashes = false;
+ }]);
+ * ```
+ *
+ * @param {string} url A parameterized URL template with parameters prefixed by `:` as in
+ * `/user/:username`. If you are using a URL with a port number (e.g.
+ * `http://example.com:8080/api`), it will be respected.
+ *
+ * If you are using a url with a suffix, just add the suffix, like this:
+ * `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
+ * or even `$resource('http://example.com/resource/:resource_id.:format')`
+ * If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
+ * collapsed down to a single `.`. If you need this sequence to appear and not collapse then you
+ * can escape it with `/\.`.
+ *
+ * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
+ * `actions` methods. If a parameter value is a function, it will be called every time
+ * a param value needs to be obtained for a request (unless the param was overridden). The function
+ * will be passed the current data value as an argument.
+ *
+ * Each key value in the parameter object is first bound to url template if present and then any
+ * excess keys are appended to the url search query after the `?`.
+ *
+ * Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
+ * URL `/path/greet?salutation=Hello`.
+ *
+ * If the parameter value is prefixed with `@`, then the value for that parameter will be
+ * extracted from the corresponding property on the `data` object (provided when calling a
+ * "non-GET" action method).
+ * For example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of
+ * `someParam` will be `data.someProp`.
+ * Note that the parameter will be ignored, when calling a "GET" action method (i.e. an action
+ * method that does not accept a request body)
+ *
+ * @param {Object.<Object>=} actions Hash with declaration of custom actions that should extend
+ * the default set of resource actions. The declaration should be created in the format of {@link
+ * ng.$http#usage $http.config}:
+ *
+ * {action1: {method:?, params:?, isArray:?, headers:?, ...},
+ * action2: {method:?, params:?, isArray:?, headers:?, ...},
+ * ...}
+ *
+ * Where:
+ *
+ * - **`action`** – {string} – The name of action. This name becomes the name of the method on
+ * your resource object.
+ * - **`method`** – {string} – Case insensitive HTTP method (e.g. `GET`, `POST`, `PUT`,
+ * `DELETE`, `JSONP`, etc).
+ * - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of
+ * the parameter value is a function, it will be called every time when a param value needs to
+ * be obtained for a request (unless the param was overridden). The function will be passed the
+ * current data value as an argument.
+ * - **`url`** – {string} – action specific `url` override. The url templating is supported just
+ * like for the resource-level urls.
+ * - **`isArray`** – {boolean=} – If true then the returned object for this action is an array,
+ * see `returns` section.
+ * - **`transformRequest`** –
+ * `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+ * transform function or an array of such functions. The transform function takes the http
+ * request body and headers and returns its transformed (typically serialized) version.
+ * By default, transformRequest will contain one function that checks if the request data is
+ * an object and serializes to using `angular.toJson`. To prevent this behavior, set
+ * `transformRequest` to an empty array: `transformRequest: []`
+ * - **`transformResponse`** –
+ * `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+ * transform function or an array of such functions. The transform function takes the http
+ * response body and headers and returns its transformed (typically deserialized) version.
+ * By default, transformResponse will contain one function that checks if the response looks
+ * like a JSON string and deserializes it using `angular.fromJson`. To prevent this behavior,
+ * set `transformResponse` to an empty array: `transformResponse: []`
+ * - **`cache`** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
+ * GET request, otherwise if a cache instance built with
+ * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
+ * caching.
+ * - **`timeout`** – `{number}` – timeout in milliseconds.<br />
+ * **Note:** In contrast to {@link ng.$http#usage $http.config}, {@link ng.$q promises} are
+ * **not** supported in $resource, because the same value would be used for multiple requests.
+ * If you are looking for a way to cancel requests, you should use the `cancellable` option.
+ * - **`cancellable`** – `{boolean}` – if set to true, the request made by a "non-instance" call
+ * will be cancelled (if not already completed) by calling `$cancelRequest()` on the call's
+ * return value. Calling `$cancelRequest()` for a non-cancellable or an already
+ * completed/cancelled request will have no effect.<br />
+ * - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the
+ * XHR object. See
+ * [requests with credentials](https://developer.mozilla.org/en/http_access_control#section_5)
+ * for more information.
+ * - **`responseType`** - `{string}` - see
+ * [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
+ * - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -
+ * `response` and `responseError`. Both `response` and `responseError` interceptors get called
+ * with `http response` object. See {@link ng.$http $http interceptors}.
+ *
+ * @param {Object} options Hash with custom settings that should extend the
+ * default `$resourceProvider` behavior. The supported options are:
+ *
+ * - **`stripTrailingSlashes`** – {boolean} – If true then the trailing
+ * slashes from any calculated URL will be stripped. (Defaults to true.)
+ * - **`cancellable`** – {boolean} – If true, the request made by a "non-instance" call will be
+ * cancelled (if not already completed) by calling `$cancelRequest()` on the call's return value.
+ * This can be overwritten per action. (Defaults to false.)
+ *
+ * @returns {Object} A resource "class" object with methods for the default set of resource actions
+ * optionally extended with custom `actions`. The default set contains these actions:
+ * ```js
+ * { 'get': {method:'GET'},
+ * 'save': {method:'POST'},
+ * 'query': {method:'GET', isArray:true},
+ * 'remove': {method:'DELETE'},
+ * 'delete': {method:'DELETE'} };
+ * ```
+ *
+ * Calling these methods invoke an {@link ng.$http} with the specified http method,
+ * destination and parameters. When the data is returned from the server then the object is an
+ * instance of the resource class. The actions `save`, `remove` and `delete` are available on it
+ * as methods with the `$` prefix. This allows you to easily perform CRUD operations (create,
+ * read, update, delete) on server-side data like this:
+ * ```js
+ * var User = $resource('/user/:userId', {userId:'@id'});
+ * var user = User.get({userId:123}, function() {
+ * user.abc = true;
+ * user.$save();
+ * });
+ * ```
+ *
+ * It is important to realize that invoking a $resource object method immediately returns an
+ * empty reference (object or array depending on `isArray`). Once the data is returned from the
+ * server the existing reference is populated with the actual data. This is a useful trick since
+ * usually the resource is assigned to a model which is then rendered by the view. Having an empty
+ * object results in no rendering, once the data arrives from the server then the object is
+ * populated with the data and the view automatically re-renders itself showing the new data. This
+ * means that in most cases one never has to write a callback function for the action methods.
+ *
+ * The action methods on the class object or instance object can be invoked with the following
+ * parameters:
+ *
+ * - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
+ * - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`
+ * - non-GET instance actions: `instance.$action([parameters], [success], [error])`
+ *
+ *
+ * Success callback is called with (value, responseHeaders) arguments, where the value is
+ * the populated resource instance or collection object. The error callback is called
+ * with (httpResponse) argument.
+ *
+ * Class actions return empty instance (with additional properties below).
+ * Instance actions return promise of the action.
+ *
+ * The Resource instances and collections have these additional properties:
+ *
+ * - `$promise`: the {@link ng.$q promise} of the original server interaction that created this
+ * instance or collection.
+ *
+ * On success, the promise is resolved with the same resource instance or collection object,
+ * updated with data from server. This makes it easy to use in
+ * {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view
+ * rendering until the resource(s) are loaded.
+ *
+ * On failure, the promise is rejected with the {@link ng.$http http response} object, without
+ * the `resource` property.
+ *
+ * If an interceptor object was provided, the promise will instead be resolved with the value
+ * returned by the interceptor.
+ *
+ * - `$resolved`: `true` after first server interaction is completed (either with success or
+ * rejection), `false` before that. Knowing if the Resource has been resolved is useful in
+ * data-binding.
+ *
+ * The Resource instances and collections have these additional methods:
+ *
+ * - `$cancelRequest`: If there is a cancellable, pending request related to the instance or
+ * collection, calling this method will abort the request.
+ *
+ * The Resource instances have these additional methods:
+ *
+ * - `toJSON`: It returns a simple object without any of the extra properties added as part of
+ * the Resource API. This object can be serialized through {@link angular.toJson} safely
+ * without attaching Angular-specific fields. Notice that `JSON.stringify` (and
+ * `angular.toJson`) automatically use this method when serializing a Resource instance
+ * (see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#toJSON()_behavior)).
+ *
+ * @example
+ *
+ * # Credit card resource
+ *
+ * ```js
+ // Define CreditCard class
+ var CreditCard = $resource('/user/:userId/card/:cardId',
+ {userId:123, cardId:'@id'}, {
+ charge: {method:'POST', params:{charge:true}}
+ });
+
+ // We can retrieve a collection from the server
+ var cards = CreditCard.query(function() {
+ // GET: /user/123/card
+ // server returns: [ {id:456, number:'1234', name:'Smith'} ];
+
+ var card = cards[0];
+ // each item is an instance of CreditCard
+ expect(card instanceof CreditCard).toEqual(true);
+ card.name = "J. Smith";
+ // non GET methods are mapped onto the instances
+ card.$save();
+ // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
+ // server returns: {id:456, number:'1234', name: 'J. Smith'};
+
+ // our custom method is mapped as well.
+ card.$charge({amount:9.99});
+ // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
+ });
+
+ // we can create an instance as well
+ var newCard = new CreditCard({number:'0123'});
+ newCard.name = "Mike Smith";
+ newCard.$save();
+ // POST: /user/123/card {number:'0123', name:'Mike Smith'}
+ // server returns: {id:789, number:'0123', name: 'Mike Smith'};
+ expect(newCard.id).toEqual(789);
+ * ```
+ *
+ * The object returned from this function execution is a resource "class" which has "static" method
+ * for each action in the definition.
+ *
+ * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and
+ * `headers`.
+ *
+ * @example
+ *
+ * # User resource
+ *
+ * When the data is returned from the server then the object is an instance of the resource type and
+ * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
+ * operations (create, read, update, delete) on server-side data.
+
+ ```js
+ var User = $resource('/user/:userId', {userId:'@id'});
+ User.get({userId:123}, function(user) {
+ user.abc = true;
+ user.$save();
+ });
+ ```
+ *
+ * It's worth noting that the success callback for `get`, `query` and other methods gets passed
+ * in the response that came from the server as well as $http header getter function, so one
+ * could rewrite the above example and get access to http headers as:
+ *
+ ```js
+ var User = $resource('/user/:userId', {userId:'@id'});
+ User.get({userId:123}, function(user, getResponseHeaders){
+ user.abc = true;
+ user.$save(function(user, putResponseHeaders) {
+ //user => saved user object
+ //putResponseHeaders => $http header getter
+ });
+ });
+ ```
+ *
+ * You can also access the raw `$http` promise via the `$promise` property on the object returned
+ *
+ ```
+ var User = $resource('/user/:userId', {userId:'@id'});
+ User.get({userId:123})
+ .$promise.then(function(user) {
+ $scope.user = user;
+ });
+ ```
+ *
+ * @example
+ *
+ * # Creating a custom 'PUT' request
+ *
+ * In this example we create a custom method on our resource to make a PUT request
+ * ```js
+ * var app = angular.module('app', ['ngResource', 'ngRoute']);
+ *
+ * // Some APIs expect a PUT request in the format URL/object/ID
+ * // Here we are creating an 'update' method
+ * app.factory('Notes', ['$resource', function($resource) {
+ * return $resource('/notes/:id', null,
+ * {
+ * 'update': { method:'PUT' }
+ * });
+ * }]);
+ *
+ * // In our controller we get the ID from the URL using ngRoute and $routeParams
+ * // We pass in $routeParams and our Notes factory along with $scope
+ * app.controller('NotesCtrl', ['$scope', '$routeParams', 'Notes',
+ function($scope, $routeParams, Notes) {
+ * // First get a note object from the factory
+ * var note = Notes.get({ id:$routeParams.id });
+ * $id = note.id;
+ *
+ * // Now call update passing in the ID first then the object you are updating
+ * Notes.update({ id:$id }, note);
+ *
+ * // This will PUT /notes/ID with the note object in the request payload
+ * }]);
+ * ```
+ *
+ * @example
+ *
+ * # Cancelling requests
+ *
+ * If an action's configuration specifies that it is cancellable, you can cancel the request related
+ * to an instance or collection (as long as it is a result of a "non-instance" call):
+ *
+ ```js
+ // ...defining the `Hotel` resource...
+ var Hotel = $resource('/api/hotel/:id', {id: '@id'}, {
+ // Let's make the `query()` method cancellable
+ query: {method: 'get', isArray: true, cancellable: true}
+ });
+
+ // ...somewhere in the PlanVacationController...
+ ...
+ this.onDestinationChanged = function onDestinationChanged(destination) {
+ // We don't care about any pending request for hotels
+ // in a different destination any more
+ this.availableHotels.$cancelRequest();
+
+ // Let's query for hotels in '<destination>'
+ // (calls: /api/hotel?location=<destination>)
+ this.availableHotels = Hotel.query({location: destination});
+ };
+ ```

+ * @description
+ * Object containing default options used when creating `$resource` instances.
+ *
+ * The default values satisfy a wide range of usecases, but you may choose to overwrite any of
+ * them to further customize your instances. The available properties are:
+ *
+ * - **stripTrailingSlashes** – `{boolean}` – If true, then the trailing slashes from any
+ * calculated URL will be stripped.<br />
+ * (Defaults to true.)
+ * - **cancellable** – `{boolean}` – If true, the request made by a "non-instance" call will be
+ * cancelled (if not already completed) by calling `$cancelRequest()` on the call's return
+ * value. For more details, see {@link ngResource.$resource}. This can be overwritten per
+ * resource class or action.<br />
+ * (Defaults to false.)
+ * - **actions** - `{Object.<Object>}` - A hash with default actions declarations. Actions are
+ * high-level methods corresponding to RESTful actions/methods on resources. An action may
+ * specify what HTTP method to use, what URL to hit, if the return value will be a single
+ * object or a collection (array) of objects etc. For more details, see
+ * {@link ngResource.$resource}. The actions can also be enhanced or overwritten per resource
+ * class.<br />
+ * The default actions are:
+ * ```js
+ * {
+ * get: {method: 'GET'},
+ * save: {method: 'POST'},
+ * query: {method: 'GET', isArray: true},
+ * remove: {method: 'DELETE'},
+ * delete: {method: 'DELETE'}
+ * }
+ * ```
+ *
+ * #### Example
+ *
+ * For example, you can specify a new `update` action that uses the `PUT` HTTP verb:
+ *
+ * ```js
+ * angular.
+ * module('myApp').
+ * config(['resourceProvider', function ($resourceProvider) {
+ * $resourceProvider.defaults.actions.update = {
+ * method: 'PUT'
+ * };
+ * });
+ * ```
+ *
+ * Or you can even overwrite the whole `actions` list and specify your own:
+ *
+ * ```js
+ * angular.
+ * module('myApp').
+ * config(['resourceProvider', function ($resourceProvider) {
+ * $resourceProvider.defaults.actions = {
+ * create: {method: 'POST'}
+ * get: {method: 'GET'},
+ * getAll: {method: 'GET', isArray:true},
+ * update: {method: 'PUT'},
+ * delete: {method: 'DELETE'}
+ * };
+ * });
+ * ```

+ *
+ * @description
+ * Resolves a set of invocables. An invocable is a function to be invoked via
+ * `$injector.invoke()`, and can have an arbitrary number of dependencies.
+ * An invocable can either return a value directly,
+ * or a `$q` promise. If a promise is returned it will be resolved and the
+ * resulting value will be used instead. Dependencies of invocables are resolved
+ * (in this order of precedence)
+ *
+ * - from the specified `locals`
+ * - from another invocable that is part of this `$resolve` call
+ * - from an invocable that is inherited from a `parent` call to `$resolve`
+ * (or recursively
+ * - from any ancestor `$resolve` of that parent).
+ *
+ * The return value of `$resolve` is a promise for an object that contains
+ * (in this order of precedence)
+ *
+ * - any `locals` (if specified)
+ * - the resolved return values of all injectables
+ * - any values inherited from a `parent` call to `$resolve` (if specified)
+ *
+ * The promise will resolve after the `parent` promise (if any) and all promises
+ * returned by injectables have been resolved. If any invocable
+ * (or `$injector.invoke`) throws an exception, or if a promise returned by an
+ * invocable is rejected, the `$resolve` promise is immediately rejected with the
+ * same error. A rejection of a `parent` promise (if specified) will likewise be
+ * propagated immediately. Once the `$resolve` promise has been rejected, no
+ * further invocables will be called.
+ *
+ * Cyclic dependencies between invocables are not permitted and will cause `$resolve`
+ * to throw an error. As a special case, an injectable can depend on a parameter
+ * with the same name as the injectable, which will be fulfilled from the `parent`
+ * injectable of the same name. This allows inherited values to be decorated.
+ * Note that in this case any other injectable in the same `$resolve` with the same
+ * dependency would see the decorated value, not the inherited value.
+ *
+ * Note that missing dependencies -- unlike cyclic dependencies -- will cause an
+ * (asynchronous) rejection of the `$resolve` promise rather than a (synchronous)
+ * exception.
+ *
+ * Invocables are invoked eagerly as soon as all dependencies are available.
+ * This is true even for dependencies inherited from a `parent` call to `$resolve`.
+ *
+ * As a special case, an invocable can be a string, in which case it is taken to
+ * be a service name to be passed to `$injector.get()`. This is supported primarily
+ * for backwards-compatibility with the `resolve` property of `$routeProvider`
+ * routes.
+ *
+ * @param {object} invocables functions to invoke or
+ * `$injector` services to fetch.
+ * @param {object} locals values to make available to the injectables

+/**
+ * @ngdoc object
+ * @name ui.router.util.type:UrlMatcher
+ *
+ * @description
+ * Matches URLs against patterns and extracts named parameters from the path or the search
+ * part of the URL. A URL pattern consists of a path pattern, optionally followed by '?' and a list
+ * of search parameters. Multiple search parameter names are separated by '&'. Search parameters
+ * do not influence whether or not a URL is matched, but their values are passed through into
+ * the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
+ *
+ * Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
+ * syntax, which optionally allows a regular expression for the parameter to be specified:
+ *
+ * * `':'` name - colon placeholder
+ * * `'*'` name - catch-all placeholder
+ * * `'{' name '}'` - curly placeholder
+ * * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
+ * regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
+ *
+ * Parameter names may contain only word characters (latin letters, digits, and underscore) and
+ * must be unique within the pattern (across both path and search parameters). For colon
+ * placeholders or curly placeholders without an explicit regexp, a path parameter matches any
+ * number of characters other than '/'. For catch-all placeholders the path parameter matches
+ * any number of characters.
+ *
+ * Examples:
+ *
+ * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
+ * trailing slashes, and patterns have to match the entire path, not just a prefix.
+ * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
+ * '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
+ * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
+ * * `'/user/{id:[^/]*}'` - Same as the previous example.
+ * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
+ * parameter consists of 1 to 8 hex digits.
+ * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
+ * path into the parameter 'path'.
+ * * `'/files/*path'` - ditto.
+ * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
+ * in the built-in `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start
+ *
+ * @param {string} pattern The pattern to compile into a matcher.
+ * @param {Object} config A configuration object hash:
+ * @param {Object=} parentMatcher Used to concatenate the pattern/config onto
+ * an existing UrlMatcher
+ *
+ * * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`.
+ * * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`.
+ *
+ * @property {string} prefix A static prefix of this pattern. The matcher guarantees that any
+ * URL matching this matcher (i.e. any string for which {@link ui.router.util.type:UrlMatcher#methods_exec exec()} returns
+ * non-null) will start with this prefix.
+ *
+ * @property {string} source The pattern that was passed into the constructor
+ *
+ * @property {string} sourcePath The path portion of the source property
+ *
+ * @property {string} sourceSearch The search portion of the source property
+ *
+ * @property {string} regex The constructed regex that will be used to match against the url when
+ * it is time to determine which url will match.

+ * See {@link ui.router.util.type:Type `Type`} for information on the values accepted.
+ *
+ * @returns {Object} Returns `$urlMatcherFactoryProvider`.
+ *
+ * @example
+ * This is a simple example of a custom type that encodes and decodes items from an
+ * array, using the array index as the URL-encoded value:
+ *
+ * <pre>
+ * var list = ['John', 'Paul', 'George', 'Ringo'];

+ * // ...
+ *
+ * // Changes URL to '/list/3', logs "Ringo" to the console
+ * $state.go('list', { item: "Ringo" });
+ * </pre>
+ *
+ * This is a more complex example of a type that relies on dependency injection to
+ * interact with services, and uses the parameter name from the URL to infer how to
+ * handle encoding and decoding parameter values:
+ *
+ * <pre>
+ * // Defines a custom type that gets a value from a service,
+ * // where each service gets different types of values from
+ * // a backend API:
+ * $urlMatcherFactoryProvider.type('dbObject', {}, function(Users, Posts) {
+ *
+ * // Matches up services to URL parameter names
+ * var services = {
+ * user: Users,
+ * post: Posts
+ * };

+ * return {
+ * encode: function(object) {
+ * // Represent the object in the URL using its unique ID
+ * return object.id;
+ * },
+ * decode: function(value, key) {
+ * // Look up the object by ID, using the parameter
+ * // name (key) to call the correct service
+ * return services[key].findById(value);
+ * },
+ * is: function(object, key) {
+ * // Check that object is a valid dbObject
+ * return angular.isObject(object) && object.id && services[key];
+ * }
+ * equals: function(a, b) {
+ * // Check the equality of decoded objects by comparing

+ * return a.id === b.id;
+ * }
+ * };

+ *
+ * // In a config() block, you can then attach URLs with

+ * @methodOf ui.router.state.$stateProvider
+ *
+ * @description
+ * Allows you to extend (carefully) or override (at your own peril) the
+ * `stateBuilder` object used internally by `$stateProvider`. This can be used
+ * to add custom functionality to ui-router, for example inferring templateUrl
+ * based on the state name.
+ *
+ * When passing only a name, it returns the current (original or decorated) builder
+ * function that matches `name`.
+ *
+ * The builder functions that can be decorated are listed below. Though not all
+ * necessarily have a good use case for decoration, that is up to you to decide.
+ *
+ * In addition, users can attach custom decorators, which will generate new
+ * properties within the state's internal definition. There is currently no clear
+ * use-case for this beyond accessing internal states (i.e. $state.$current),
+ * however, expect this to become increasingly relevant as we introduce additional
+ * meta-programming features.
+ *
+ * **Warning**: Decorators should not be interdependent because the order of
+ * execution of the builder functions in non-deterministic. Builder functions
+ * should only be dependent on the state definition object and super function.
+ *
+ *
+ * Existing builder functions and current return values:
+ *
+ * - **parent** `{object}` - returns the parent state object.
+ * - **data** `{object}` - returns state data, including any inherited data that is not
+ * overridden by own values (if any).
+ * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
+ * or `null`.
+ * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is
+ * navigable).
+ * - **params** `{object}` - returns an array of state params that are ensured to
+ * be a super-set of parent's params.
+ * - **views** `{object}` - returns a views object where each key is an absolute view
+ * name (i.e. "viewName@stateName") and each value is the config object
+ * (template, controller) for the view. Even when you don't use the views object
+ * explicitly on a state config, one is still created for you internally.
+ * So by decorating this builder function you have access to decorating template
+ * and controller properties.
+ * - **ownParams** `{object}` - returns an array of params that belong to the state,
+ * not including any params defined by ancestor states.
+ * - **path** `{string}` - returns the full path from the root down to this state.
+ * Needed for state activation.
+ * - **includes** `{object}` - returns an object that includes every state that
+ * would pass a `$state.includes()` test.

+ * Targets three named `ui-view`s in the parent state's template
+ * <pre>views: {

+ * controller: "headerCtrl",

+ * controller: "bodyCtrl",

+ * <pre>views: {

+ * templateUrl: "msgHeader.html"
+ * }, 'body': {
+ * controller: "messagesCtrl",
+ * templateUrl: "messages.html"
+ * }
+ * }</pre>
+ *
+ * @param {boolean=} [stateConfig.abstract=false]
+ * <a id='abstract'></a>
+ * An abstract state will never be directly activated,
+ * but can provide inherited properties to its common children states.
+ * <pre>abstract: true</pre>
+ *
+ * @param {function=} stateConfig.onEnter
+ * <a id='onEnter'></a>
+ *
+ * Callback function for when a state is entered. Good way
+ * to trigger an action or dispatch an event, such as opening a dialog.
+ * If minifying your scripts, make sure to explicitly annotate this function,
+ * because it won't be automatically annotated by your build tools.
+ *
+ * <pre>onEnter: function(MyService, $stateParams) {
+ * MyService.foo($stateParams.myParam);
+ * }</pre>
+ *
+ * @param {function=} stateConfig.onExit
+ * <a id='onExit'></a>

+ * Callback function for when a state is exited. Good way to
+ * trigger an action or dispatch an event, such as opening a dialog.
+ * If minifying your scripts, make sure to explicitly annotate this function,
+ * because it won't be automatically annotated by your build tools.
+ *
+ * <pre>onExit: function(MyService, $stateParams) {
+ * MyService.cleanup($stateParams.myParam);
+ * }</pre>
+ *
+ * @param {boolean=} [stateConfig.reloadOnSearch=true]
+ * <a id='reloadOnSearch'></a>
+ *
+ * If `false`, will not retrigger the same state
+ * just because a search/query parameter has changed (via $location.search() or $location.hash()).
+ * Useful for when you'd like to modify $location.search() without triggering a reload.
+ * <pre>reloadOnSearch: false</pre>
+ *
+ * @param {object=} stateConfig.data
+ * <a id='data'></a>
+ *
+ * Arbitrary data object, useful for custom configuration. The parent state's `data` is
+ * prototypally inherited. In other words, adding a data property to a state adds it to
+ * the entire subtree via prototypal inheritance.
+ *
+ * <pre>data: {
+ * requiredRole: 'foo'
+ * } </pre>
+ *
+ * @param {object=} stateConfig.params
+ * <a id='params'></a>
+ *
+ * A map which optionally configures parameters declared in the `url`, or
+ * defines additional non-url parameters. For each parameter being
+ * configured, add a configuration object keyed to the name of the parameter.
+ *
+ * Each parameter configuration object may contain the following properties:
+ *
+ * - ** value ** - {object|function=}: specifies the default value for this
+ * parameter. This implicitly sets this parameter as optional.
+ *
+ * When UI-Router routes to a state and no value is
+ * specified for this parameter in the URL or transition, the
+ * default value will be used instead. If `value` is a function,
+ * it will be injected and invoked, and the return value used.
+ *
+ * *Note*: `undefined` is treated as "no default value" while `null`
+ * is treated as "the default value is `null`".
+ *
+ * *Shorthand*: If you only need to configure the default value of the
+ * parameter, you may use a shorthand syntax. In the **`params`**
+ * map, instead mapping the param name to a full parameter configuration
+ * object, simply set map it to the default parameter value, e.g.:
+ *
+ * <pre>// define a parameter's default value
+ * params: {
+ * param1: { value: "defaultValue" }
+ * }
+ * // shorthand default values
+ * params: {
+ * param1: "defaultValue",
+ * param2: "param2Default"
+ * }</pre>
+ *
+ * - ** array ** - {boolean=}: *(default: false)* If true, the param value will be
+ * treated as an array of values. If you specified a Type, the value will be
+ * treated as an array of the specified Type. Note: query parameter values
+ * default to a special `"auto"` mode.
+ *
+ * For query parameters in `"auto"` mode, if multiple values for a single parameter
+ * are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values
+ * are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`). However, if
+ * only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single
+ * value (e.g.: `{ foo: '1' }`).
+ *
+ * <pre>params: {
+ * param1: { array: true }
+ * }</pre>
+ *
+ * - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
+ * the current parameter value is the same as the default value. If `squash` is not set, it uses the
+ * configured default squash policy.
+ * (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
+ *
+ * There are three squash settings:
+ *
+ * - false: The parameter's default value is not squashed. It is encoded and included in the URL
+ * - true: The parameter's default value is omitted from the URL. If the parameter is preceeded and followed
+ * by slashes in the state's `url` declaration, then one of those slashes are omitted.
+ * This can allow for cleaner looking URLs.
+ * - `"<arbitrary string>"`: The parameter's default value is replaced with an arbitrary placeholder of your choice.
+ *
+ * <pre>params: {
+ * param1: {
+ * value: "defaultId",
+ * squash: true
+ * } }
+ * // squash "defaultValue" to "~"
+ * params: {
+ * param1: {
+ * value: "defaultValue",
+ * squash: "~"
+ * } }
+ * </pre>
+ *
+ *
+ * @example
+ * <pre>
+ * // Some state name examples
+ *
+ * // stateName can be a single top-level name (must be unique).
+ * $stateProvider.state("home", {});
+ *
+ * // Or it can be a nested state name. This state is a child of the
+ * // above "home" state.
+ * $stateProvider.state("home.newest", {});
+ *
+ * // Nest states as deeply as needed.
+ * $stateProvider.state("home.newest.abc.xyz.inception", {});
+ *
+ * // state() returns $stateProvider, so you can chain state declarations.

+ * - `$state.go('^.sibling')` - will go to a sibling state
+ * - `$state.go('.child.grandchild')` - will go to grandchild state
+ *
+ * @param {object=} params A map of the parameters that will be sent to the state,
+ * will populate $stateParams. Any parameters that are not specified will be inherited from currently
+ * defined parameters. Only parameters specified in the state definition can be overridden, new
+ * parameters will be ignored. This allows, for example, going to a sibling state that shares parameters
+ * specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
+ * transitioning to a sibling will get you the parameters for all parents, transitioning to a child
+ * will get you all current parameters, etc.
+ * @param {object=} options Options object. The options are:
+ *
+ * - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
+ * will not. If string, must be `"replace"`, which will update url and also replace last history record.
+ * - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
+ * - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'),
+ * defines which state to be relative from.
+ * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
+ * - **`reload`** (v0.2.5) - {boolean=false|string|object}, If `true` will force transition even if no state or params
+ * have changed. It will reload the resolves and views of the current state and parent states.
+ * If `reload` is a string (or state object), the state object is fetched (by name, or object reference); and \

+ * @requires ui.router.state.$uiViewScroll
+ * @requires $document
+ *
+ * @restrict ECA
+ *
+ * @description
+ * The ui-view directive tells $state where to place your templates.
+ *
+ * @param {string=} name A view name. The name should be unique amongst the other views in the
+ * same state. You can have views of the same name that live in different states.
+ *
+ * @param {string=} autoscroll It allows you to set the scroll behavior of the browser window
+ * when a view is populated. By default, $anchorScroll is overridden by ui-router's custom scroll
+ * service, {@link ui.router.state.$uiViewScroll}. This custom service let's you
+ * scroll ui-view elements into view when they are populated during a state activation.
+ *
+ * *Note: To revert back to old [`$anchorScroll`](http://docs.angularjs.org/api/ng.$anchorScroll)
+ * functionality, call `$uiViewScrollProvider.useAnchorScroll()`.*
+ *
+ * @param {string=} onload Expression to evaluate whenever the view updates.
+ *
+ * @example
+ * A view can be unnamed or named.
+ * <pre>
+ * <!-- Unnamed -->
+ * <div ui-view></div>
+ *
+ * <!-- Named -->
+ * <div ui-view="viewName"></div>
+ * </pre>
+ *
+ * You can only have one unnamed view within any template (or root html). If you are only using a
+ * single view and it is unnamed then you can populate it like so:
+ * <pre>
+ * <div ui-view></div>
+ * $stateProvider.state("home", {
+ * template: "<h1>HELLO!</h1>"
+ * })
+ * </pre>
+ *
+ * The above is a convenient shortcut equivalent to specifying your view explicitly with the {@link ui.router.state.$stateProvider#methods_state `views`}
+ * config property, by name, in this case an empty name:
+ * <pre>
+ * $stateProvider.state("home", {
+ * views: {
+ * "": {
+ * template: "<h1>HELLO!</h1>"
+ * }
+ * }
+ * })
+ * </pre>
+ *
+ * But typically you'll only use the views property if you name your view or have more than one view
+ * in the same template. There's not really a compelling reason to name a view if its the only one,
+ * but you could if you wanted, like so:
+ * <pre>
+ * <div ui-view="main"></div>
+ * </pre>
+ * <pre>
+ * $stateProvider.state("home", {
+ * views: {
+ * "main": {
+ * template: "<h1>HELLO!</h1>"
+ * }
+ * }
+ * })
+ * </pre>
+ *
+ * Really though, you'll use views to set up multiple views:
+ * <pre>
+ * <div ui-view></div>
+ * <div ui-view="chart"></div>
+ * <div ui-view="data"></div>
+ * </pre>
+ *
+ * <pre>
+ * $stateProvider.state("home", {
+ * views: {
+ * "": {
+ * template: "<h1>HELLO!</h1>"
+ * },
+ * "chart": {
+ * template: "<chart_thing/>"
+ * },
+ * "data": {
+ * template: "<data_thing/>"
+ * }
+ * }
+ * })
+ * </pre>
+ *
+ * Examples for `autoscroll`:
+ *
+ * <pre>
+ * <!-- If autoscroll present with no expression,
+ * then scroll ui-view into view -->
+ * <ui-view autoscroll/>
+ *
+ * <!-- If autoscroll present with valid expression,
+ * then scroll ui-view into view if expression evaluates to true -->
+ * <ui-view autoscroll='true'/>
+ * <ui-view autoscroll='false'/>
+ * <ui-view autoscroll='scopeVariable'/>
+ * </pre>
+ *
+ * Resolve data:
+ *
+ * The resolved data from the state's `resolve` block is placed on the scope as `$resolve` (this
+ * can be customized using [[ViewDeclaration.resolveAs]]). This can be then accessed from the template.
+ *
+ * Note that when `controllerAs` is being used, `$resolve` is set on the controller instance *after* the
+ * controller is instantiated. The `$onInit()` hook can be used to perform initialization code which
+ * depends on `$resolve` data.
+ *
+ * Example usage of $resolve in a view template
+ * <pre>
+ * $stateProvider.state('home', {
+ * template: '<my-component user="$resolve.user"></my-component>',
+ * resolve: {
+ * user: function(UserService) { return UserService.fetchUser(); }
+ * }
+ * });

+ * @restrict A
+ *
+ * @description
+ * A directive that binds a link (`<a>` tag) to a state. If the state has an associated
+ * URL, the directive will automatically generate & update the `href` attribute via
+ * the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking
+ * the link will trigger a state transition with optional parameters.
+ *
+ * Also middle-clicking, right-clicking, and ctrl-clicking on the link will be
+ * handled natively by the browser.
+ *
+ * You can also use relative state paths within ui-sref, just like the relative
+ * paths passed to `$state.go()`. You just need to be aware that the path is relative
+ * to the state that the link lives in, in other words the state that loaded the
+ * template containing the link.
+ *
+ * You can specify options to pass to {@link ui.router.state.$state#methods_go $state.go()}
+ * using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
+ * and `reload`.
+ *
+ * @example
+ * Here's an example of how you'd use ui-sref and how it would compile. If you have the
+ * following template:
+ * <pre>
+ * <a ui-sref="home">Home</a> | <a ui-sref="about">About</a> | <a ui-sref="{page: 2}">Next page</a>
+ *
+ * <ul>
+ * <li ng-repeat="contact in contacts">
+ * <a ui-sref="contacts.detail({ id: contact.id })">{{ contact.name }}</a>
+ * </li>
+ * </ul>
+ * </pre>
+ *
+ * Then the compiled html would be (assuming Html5Mode is off and current state is contacts):
+ * <pre>
+ * <a href="#/home" ui-sref="home">Home</a> | <a href="#/about" ui-sref="about">About</a> | <a href="#/contacts?page=2" ui-sref="{page: 2}">Next page</a>
+ *
+ * <ul>
+ * <li ng-repeat="contact in contacts">
+ * <a href="#/contacts/1" ui-sref="contacts.detail({ id: contact.id })">Joe</a>
+ * </li>
+ * <li ng-repeat="contact in contacts">
+ * <a href="#/contacts/2" ui-sref="contacts.detail({ id: contact.id })">Alice</a>

+ * <li ng-repeat="contact in contacts">
+ * <a href="#/contacts/3" ui-sref="contacts.detail({ id: contact.id })">Bob</a>

+ *
+ * <a ui-sref="home" ui-sref-opts="{reload: true}">Home</a>

+ * @requires $interpolate
+ *
+ * @restrict A
+ *
+ * @description
+ * A directive working alongside ui-sref to add classes to an element when the
+ * related ui-sref directive's state is active, and removing them when it is inactive.
+ * The primary use-case is to simplify the special appearance of navigation menus
+ * relying on `ui-sref`, by having the "active" state's menu button appear different,
+ * distinguishing it from the inactive menu items.
+ *
+ * ui-sref-active can live on the same element as ui-sref or on a parent element. The first
+ * ui-sref-active found at the same level or above the ui-sref will be used.
+ *
+ * Will activate when the ui-sref's target state or any child state is active. If you
+ * need to activate only when the ui-sref target state is active and *not* any of
+ * it's children, then you will use
+ * {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}
+ *
+ * @example
+ * Given the following template:
+ * <pre>
+ * <ul>
+ * <li ui-sref-active="active" class="item">
+ * <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
+ * </li>
+ * </ul>
+ * </pre>
+ *
+ *
+ * When the app state is "app.user" (or any children states), and contains the state parameter "user" with value "bilbobaggins",
+ * the resulting HTML will appear as (note the 'active' class):
+ * <pre>
+ * <ul>
+ * <li ui-sref-active="active" class="item active">
+ * <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
+ * </li>
+ * </ul>
+ * </pre>
+ *
+ * The class name is interpolated **once** during the directives link time (any further changes to the
+ * interpolated value are ignored).
+ *
+ * Multiple classes may be specified in a space-separated format:
+ * <pre>
+ * <ul>
+ * <li ui-sref-active='class1 class2 class3'>
+ * <a ui-sref="app.user">link</a>
+ * </li>
+ * </ul>
+ * </pre>
+ *
+ * It is also possible to pass ui-sref-active an expression that evaluates
+ * to an object hash, whose keys represent active class names and whose
+ * values represent the respective state names/globs.
+ * ui-sref-active will match if the current active state **includes** any of
+ * the specified state names/globs, even the abstract ones.
+ *
+ * @Example
+ * Given the following template, with "admin" being an abstract state:
+ * <pre>
+ * <div ui-sref-active="{'active': 'admin.*'}">
+ * <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
+ * </div>
+ * </pre>
+ *
+ * When the current state is "admin.roles" the "active" class will be applied
+ * to both the <div> and <a> elements. It is important to note that the state
+ * names/globs passed to ui-sref-active shadow the state provided by ui-sref.

+ * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
+ *
+ * The above creates an instance of minErr in the example namespace. The
+ * resulting error will have a namespaced error code of example.one. The
+ * resulting error will replace {0} with the value of foo, and {1} with the
+ * value of bar. The object is not restricted in the number of arguments it can
+ * take.
+ *
+ * If fewer arguments are specified than necessary for interpolation, the extra
+ * interpolation markers will be preserved in the final string.
+ *
+ * Since data will be parsed statically during a build step, some restrictions
+ * are applied with respect to how minErr instances are created and called.
+ * Instances should have names of the form namespaceMinErr for a minErr created
+ * using minErr('namespace') . Error codes, namespaces and template strings
+ * should all be static strings, not variables or general expressions.
+ *
+ * @param {string} module The namespace to use for the new minErr instance.
+ * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning
+ * error from returned function, for cases when a particular type of error is useful.
+ * @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance

+ *
+ * @element ANY
+ * @param {angular.Module} ngApp an optional application
+ * {@link angular.module module} name to load.
+ * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
+ * created in "strict-di" mode. This means that the application will fail to invoke functions which
+ * do not use explicit function annotation (and are thus unsuitable for minification), as described
+ * in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
+ * tracking down the root of these bugs.
+ *
+ * @description
+ *
+ * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
+ * designates the **root element** of the application and is typically placed near the root element
+ * of the page - e.g. on the `<body>` or `<html>` tags.
+ *
+ * There are a few things to keep in mind when using `ngApp`:
+ * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
+ * found in the document will be used to define the root element to auto-bootstrap as an
+ * application. To run multiple applications in an HTML document you must manually bootstrap them using
+ * {@link angular.bootstrap} instead.
+ * - AngularJS applications cannot be nested within each other.
+ * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
+ * This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
+ * {@link ngRoute.ngView `ngView`}.
+ * Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
+ * causing animations to stop working and making the injector inaccessible from outside the app.
+ *
+ * You can specify an **AngularJS module** to be used as the root module for the application. This
+ * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
+ * should contain the application code needed or have dependencies on other modules that will
+ * contain the code. See {@link angular.module} for more information.
+ *
+ * In the example below if the `ngApp` directive were not placed on the `html` element then the
+ * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
+ * would not be resolved to `3`.
+ *
+ * `ngApp` is the easiest, and most common way to bootstrap an application.
+ *
+ <example module="ngAppDemo">
+ <file name="index.html">
+ <div ng-controller="ngAppDemoController">
+ I can add: {{a}} + {{b}} = {{ a+b }}

+ angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
+ $scope.a = 1;
+ $scope.b = 2;
+ });
+ </file>
+ </example>
+ *
+ * Using `ngStrictDi`, you would see something like this:
+ *
+ <example ng-app-included="true">
+ <file name="index.html">
+ <div ng-app="ngAppStrictDemo" ng-strict-di>
+ <div ng-controller="GoodController1">
+ I can add: {{a}} + {{b}} = {{ a+b }}
+
+ <p>This renders because the controller does not fail to
+ instantiate, by using explicit annotation style (see

+ Hello, {{name}}!

+ </p>
+ </div>
+
+ <div ng-controller="BadController">
+ I can add: {{a}} + {{b}} = {{ a+b }}
+
+ <p>The controller could not be instantiated, due to relying

+/**
+ * @ngdoc function
+ * @name angular.element
+ * @module ng
+ * @kind function
+ *
+ * @description
+ * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
+ *
+ * If jQuery is available, `angular.element` is an alias for the
+ * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
+ * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
+ *
+ * jqLite is a tiny, API-compatible subset of jQuery that allows
+ * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
+ * commonly needed functionality with the goal of having a very small footprint.
+ *
+ * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
+ * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
+ * specific version of jQuery if multiple versions exist on the page.
+ *
+ * <div class="alert alert-info">**Note:** All element references in Angular are always wrapped with jQuery or
+ * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.</div>
+ *
+ * <div class="alert alert-warning">**Note:** Keep in mind that this function will not find elements
+ * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
+ * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.</div>
+ *
+ * ## Angular's jqLite
+ * jqLite provides only the following jQuery methods:
+ *
+ * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
+ * - [`after()`](http://api.jquery.com/after/)
+ * - [`append()`](http://api.jquery.com/append/)
+ * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
+ * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
+ * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
+ * - [`clone()`](http://api.jquery.com/clone/)
+ * - [`contents()`](http://api.jquery.com/contents/)
+ * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
+ * As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
+ * - [`data()`](http://api.jquery.com/data/)
+ * - [`detach()`](http://api.jquery.com/detach/)
+ * - [`empty()`](http://api.jquery.com/empty/)
+ * - [`eq()`](http://api.jquery.com/eq/)
+ * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
+ * - [`hasClass()`](http://api.jquery.com/hasClass/)
+ * - [`html()`](http://api.jquery.com/html/)
+ * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
+ * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
+ * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
+ * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
+ * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
+ * - [`prepend()`](http://api.jquery.com/prepend/)
+ * - [`prop()`](http://api.jquery.com/prop/)
+ * - [`ready()`](http://api.jquery.com/ready/)
+ * - [`remove()`](http://api.jquery.com/remove/)
+ * - [`removeAttr()`](http://api.jquery.com/removeAttr/)
+ * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
+ * - [`removeData()`](http://api.jquery.com/removeData/)
+ * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
+ * - [`text()`](http://api.jquery.com/text/)
+ * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
+ * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
+ * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces or event object as parameter
+ * - [`val()`](http://api.jquery.com/val/)
+ * - [`wrap()`](http://api.jquery.com/wrap/)
+ *
+ * ## jQuery/jqLite Extras
+ * Angular also provides the following additional methods and events to both jQuery and jqLite:
+ *
+ * ### Events
+ * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
+ * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM
+ * element before it is removed.
+ *
+ * ### Methods
+ * - `controller(name)` - retrieves the controller of the current element or its parent. By default
+ * retrieves controller associated with the `ngController` directive. If `name` is provided as
+ * camelCase directive name, then the controller for this directive will be retrieved (e.g.
+ * `'ngModel'`).
+ * - `injector()` - retrieves the injector of the current element or its parent.
+ * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
+ * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
+ * be enabled.
+ * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
+ * current element. This getter should be used only on elements that contain a directive which starts a new isolate
+ * scope. Calling `scope()` on this element always returns the original non-isolate scope.
+ * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
+ * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
+ * parent element is reached.
+ *
+ * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
+ * https://github.com/angular/angular.js/issues/14251 for more information.
+ *
+ * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
+ * @returns {Object} jQuery object.

+ * // inferred (only works if code not minified/obfuscated)

+ *
+ * @description
+ * Returns an array of service names which the function is requesting for injection. This API is
+ * used by the injector to determine which services need to be injected into the function when the
+ * function is invoked. There are three ways in which the function can be annotated with the needed
+ * dependencies.
+ *
+ * # Argument names
+ *
+ * The simplest form is to extract the dependencies from the arguments of the function. This is done
+ * by converting the function into a string using `toString()` method and extracting the argument
+ * names.
+ * ```js
+ * // Given
+ * function MyController($scope, $route) {
+ * // ...
+ * }
+ *
+ * // Then
+ * expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * ```
+ *
+ * You can disallow this method by using strict injection mode.
+ *
+ * This method does not work with code minification / obfuscation. For this reason the following
+ * annotation strategies are supported.
+ *
+ * # The `$inject` property
+ *
+ * If a function has an `$inject` property and its value is an array of strings, then the strings
+ * represent names of services to be injected into the function.
+ * ```js
+ * // Given
+ * var MyController = function(obfuscatedScope, obfuscatedRoute) {
+ * // ...
+ * }
+ * // Define function dependencies
+ * MyController['$inject'] = ['$scope', '$route'];
+ *
+ * // Then
+ * expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * ```
+ *
+ * # The array notation
+ *
+ * It is often desirable to inline Injected functions and that's when setting the `$inject` property
+ * is very inconvenient. In these situations using the array notation to specify the dependencies in
+ * a way that survives minification is a better choice:
+ *
+ * ```js
+ * // We wish to write this (not minification / obfuscation safe)
+ * injector.invoke(function($compile, $rootScope) {
+ * // ...
+ * });
+ *
+ * // We are forced to write break inlining
+ * var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
+ * // ...
+ * };
+ * tmpFn.$inject = ['$compile', '$rootScope'];
+ * injector.invoke(tmpFn);
+ *
+ * // To better support inline function the inline annotation is supported
+ * injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
+ * // ...
+ * }]);
+ *
+ * // Therefore
+ * expect(injector.annotate(
+ * ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
+ * ).toEqual(['$compile', '$rootScope']);
+ * ```
+ *
+ * @param {Function|Array.<string|Function>} fn Function for which dependent service names need to
+ * be retrieved as described above.

+ *
+ * An Angular **service** is a singleton object created by a **service factory**. These **service
+ * factories** are functions which, in turn, are created by a **service provider**.
+ * The **service providers** are constructor functions. When instantiated they must contain a
+ * property called `$get`, which holds the **service factory** function.
+ *
+ * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
+ * correct **service provider**, instantiating it and then calling its `$get` **service factory**
+ * function to get the instance of the **service**.
+ *
+ * Often services have no configuration options and there is no need to add methods to the service
+ * provider. The provider will be no more than a constructor function with a `$get` property. For
+ * these cases the {@link auto.$provide $provide} service has additional helper methods to register
+ * services without specifying a provider.
+ *
+ * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the

+ * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
+ * that will be wrapped in a **service provider** object, whose `$get` property will instantiate

+ *
+ * Service provider names start with the name of the service they provide followed by `Provider`.
+ * For example, the {@link ng.$log $log} service has a provider called

+ *
+ * Service provider objects can have additional methods which allow configuration of the provider
+ * and its service. Importantly, you can configure what kind of service is created by the `$get`
+ * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
+ * method {@link ng.$logProvider#debugEnabled debugEnabled}
+ * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
+ * console or not.
+ *
+ * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
+ 'Provider'` key.
+ * @param {(Object|function())} provider If the provider is:
+ *
+ * - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
+ * {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
+ * - `Constructor`: a new instance of the provider will be created using
+ * {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.

+ * Register a **constant service** with the {@link auto.$injector $injector}, such as a string,
+ * a number, an array, an object or a function. Like the {@link auto.$provide#value value}, it is not
+ * possible to inject other services into a constant.
+ *
+ * But unlike {@link auto.$provide#value value}, a constant can be
+ * injected into a module configuration function (see {@link angular.Module#config}) and it cannot
+ * be overridden by an Angular {@link auto.$provide#decorator decorator}.
+ *
+ * @param {string} name The name of the constant.
+ * @param {*} value The constant value.
+ * @returns {Object} registered instance
+ *
+ * @example
+ * Here a some examples of creating constants:
+ * ```js
+ * $provide.constant('SHARD_HEIGHT', 306);
+ *
+ * $provide.constant('MY_COLOURS', ['red', 'blue', 'grey']);
+ *
+ * $provide.constant('double', function(value) {

+/**
+ * @ngdoc method
+ * @name $provide#decorator
+ * @description
+ *
+ * Register a **decorator function** with the {@link auto.$injector $injector}. A decorator function
+ * intercepts the creation of a service, allowing it to override or modify the behavior of the
+ * service. The return value of the decorator function may be the original service, or a new service
+ * that replaces (or wraps and delegates to) the original service.
+ *
+ * You can find out more about using decorators in the {@link guide/decorators} guide.
+ *
+ * @param {string} name The name of the service to decorate.
+ * @param {Function|Array.<string|Function>} decorator This function will be invoked when the service needs to be
+ * provided and should return the decorated service instance. The function is called using
+ * the {@link auto.$injector#invoke injector.invoke} method and is therefore fully injectable.
+ * Local injection arguments:
+ *
+ * * `$delegate` - The original service instance, which can be replaced, monkey patched, configured,
+ * decorated or delegated to.
+ *
+ * @example
+ * Here we decorate the {@link ng.$log $log} service to convert warnings to errors by intercepting
+ * calls to {@link ng.$log#error $log.warn()}.
+ * ```js
+ * $provide.decorator('$log', ['$delegate', function($delegate) {
+ * $delegate.warn = $delegate.error;
+ * return $delegate;
+ * }]);

+ * match any anchor whenever it changes. This can be disabled by calling
+ * {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}.
+ *
+ * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a
+ * vertical scroll-offset (either fixed or dynamic).
+ *
+ * @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of
+ * {@link ng.$location#hash $location.hash()} will be used.
+ *
+ * @property {(number|function|jqLite)} yOffset
+ * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
+ * positioned elements at the top of the page, such as navbars, headers etc.
+ *
+ * `yOffset` can be specified in various ways:
+ * - **number**: A fixed number of pixels to be used as offset.<br /><br />
+ * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
+ * a number representing the offset (in pixels).<br /><br />
+ * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
+ * the top of the page to the element's bottom will be used as offset.<br />
+ * **Note**: The element will be taken into account only as long as its `position` is set to
+ * `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
+ * their height and/or positioning according to the viewport's size.
+ *
+ * <br />
+ * <div class="alert alert-warning">

+ *
+ * ### Life-cycle hooks
+ * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
+ * directive:
+ * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
+ * had their bindings initialized (and before the pre & post linking functions for the directives on
+ * this element). This is a good place to put initialization code for your controller.
+ * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
+ * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
+ * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
+ * component such as cloning the bound value to prevent accidental mutation of the outer value.
+ * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
+ * changes. Any actions that you wish to take in response to the changes that you detect must be
+ * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
+ * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
+ * be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
+ * if detecting changes, you must store the previous value(s) for comparison to the current values.
+ * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
+ * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
+ * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
+ * components will have their `$onDestroy()` hook called before child components.
+ * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
+ * function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
+ * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
+ * they are waiting for their template to load asynchronously and their own compilation and linking has been
+ * suspended until that occurs.
+ *
+ * #### Comparison with Angular 2 life-cycle hooks
+ * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
+ * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
+ *
+ * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
+ * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
+ * In Angular 2 you can only define hooks on the prototype of the Component class.
+ * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
+ * `ngDoCheck` in Angular 2
+ * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
+ * propagated throughout the application.
+ * Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
+ * error or do nothing depending upon the state of `enableProdMode()`.
+ *
+ * #### Life-cycle hook examples
+ *
+ * This example shows how you can check for mutations to a Date object even though the identity of the object
+ * has not changed.
+ *
+ * <example name="doCheckDateExample" module="do-check-module">
+ * <file name="app.js">
+ * angular.module('do-check-module', [])
+ * .component('app', {
+ * template:
+ * 'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' +
+ * 'Date: {{ $ctrl.date }}' +
+ * '<test date="$ctrl.date"></test>',
+ * controller: function() {
+ * this.date = new Date();
+ * this.month = this.date.getMonth();
+ * this.updateDate = function() {
+ * this.date.setMonth(this.month);
+ * };
+ * }
+ * })
+ * .component('test', {
+ * bindings: { date: '<' },
+ * template:
+ * '<pre>{{ $ctrl.log | json }}</pre>',
+ * controller: function() {
+ * var previousValue;
+ * this.log = [];
+ * this.$doCheck = function() {
+ * var currentValue = this.date && this.date.valueOf();
+ * if (previousValue !== currentValue) {
+ * this.log.push('doCheck: date mutated: ' + this.date);
+ * previousValue = currentValue;
+ * }
+ * };
+ * }
+ * });
+ * </file>
+ * <file name="index.html">
+ * <app></app>
+ * </file>
+ * </example>
+ *
+ * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
+ * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
+ * arrays or objects can have a negative impact on your application performance)
+ *
+ * <example name="doCheckArrayExample" module="do-check-module">
+ * <file name="index.html">
+ * <div ng-init="items = []">
+ * <button ng-click="items.push(items.length)">Add Item</button>
+ * <button ng-click="items = []">Reset Items</button>
+ * <pre>{{ items }}</pre>
+ * <test items="items"></test>
+ * </div>
+ * </file>
+ * <file name="app.js">
+ * angular.module('do-check-module', [])
+ * .component('test', {
+ * bindings: { items: '<' },
+ * template:
+ * '<pre>{{ $ctrl.log | json }}</pre>',
+ * controller: function() {
+ * this.log = [];
+ *
+ * this.$doCheck = function() {
+ * if (this.items_ref !== this.items) {
+ * this.log.push('doCheck: items changed');
+ * this.items_ref = this.items;
+ * }
+ * if (!angular.equals(this.items_clone, this.items)) {
+ * this.log.push('doCheck: items mutated');
+ * this.items_clone = angular.copy(this.items);
+ * }
+ * };
+ * }
+ * });
+ * </file>
+ * </example>
+ *
+ *
+ * ### Directive Definition Object
+ *
+ * The directive definition object provides instructions to the {@link ng.$compile
+ * compiler}. The attributes are:
+ *
+ * #### `multiElement`
+ * When this property is set to true, the HTML compiler will collect DOM nodes between
+ * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
+ * together as the directive elements. It is recommended that this feature be used on directives
+ * which are not strictly behavioral (such as {@link ngClick}), and which
+ * do not manipulate or replace child nodes (such as {@link ngInclude}).
+ *
+ * #### `priority`
+ * When there are multiple directives defined on a single DOM element, sometimes it
+ * is necessary to specify the order in which the directives are applied. The `priority` is used
+ * to sort the directives before their `compile` functions get called. Priority is defined as a
+ * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
+ * are also run in priority order, but post-link functions are run in reverse order. The order
+ * of directives with the same priority is undefined. The default priority is `0`.
+ *
+ * #### `terminal`
+ * If set to true then the current `priority` will be the last set of directives
+ * which will execute (any directives at the current priority will still execute
+ * as the order of execution on same `priority` is undefined). Note that expressions
+ * and other directives used in the directive's template will also be excluded from execution.
+ *
+ * #### `scope`
+ * The scope property can be `true`, an object or a falsy value:
+ *
+ * * **falsy:** No scope will be created for the directive. The directive will use its parent's scope.
+ *
+ * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
+ * the directive's element. If multiple directives on the same element request a new scope,
+ * only one new scope is created. The new scope rule does not apply for the root of the template
+ * since the root of the template always gets a new scope.
+ *
+ * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The
+ * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent
+ * scope. This is useful when creating reusable components, which should not accidentally read or modify
+ * data in the parent scope.
+ *
+ * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
+ * directive's element. These local properties are useful for aliasing values for templates. The keys in
+ * the object hash map to the name of the property on the isolate scope; the values define how the property
+ * is bound to the parent scope, via matching attributes on the directive's element:
+ *
+ * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
+ * always a string since DOM attributes are strings. If no `attr` name is specified then the
+ * attribute name is assumed to be the same as the local name. Given `<my-component
+ * my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`,
+ * the directive's scope property `localName` will reflect the interpolated value of `hello
+ * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
+ * scope. The `name` is read from the parent scope (not the directive's scope).
+ *
+ * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
+ * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
+ * If no `attr` name is specified then the attribute name is assumed to be the same as the local
+ * name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: {
+ * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
+ * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
+ * `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
+ * `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
+ * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
+ * will be thrown upon discovering changes to the local value, since it will be impossible to sync
+ * them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
+ * method is used for tracking changes, and the equality check is based on object identity.
+ * However, if an object literal or an array literal is passed as the binding expression, the
+ * equality check is done by value (using the {@link angular.equals} function). It's also possible
+ * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
+ * `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
+ *
+ * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an
+ * expression passed via the attribute `attr`. The expression is evaluated in the context of the
+ * parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the
+ * local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`.
+ *
+ * For example, given `<my-component my-attr="parentModel">` and directive definition of
+ * `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the
+ * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
+ * in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however
+ * two caveats:
+ * 1. one-way binding does not copy the value from the parent to the isolate scope, it simply
+ * sets the same value. That means if your bound value is an object, changes to its properties
+ * in the isolated scope will be reflected in the parent scope (because both reference the same object).
+ * 2. one-way binding watches changes to the **identity** of the parent value. That means the
+ * {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference
+ * to the value has changed. In most cases, this should not be of concern, but can be important
+ * to know if you one-way bind to an object, and then replace that object in the isolated scope.
+ * If you now change a property of the object in your parent scope, the change will not be
+ * propagated to the isolated scope, because the identity of the object on the parent scope
+ * has not changed. Instead you must assign a new object.
+ *
+ * One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings
+ * back to the parent. However, it does not make this completely impossible.
+ *
+ * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If
+ * no `attr` name is specified then the attribute name is assumed to be the same as the local name.
+ * Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: {
+ * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
+ * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
+ * via an expression to the parent scope. This can be done by passing a map of local variable names
+ * and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
+ * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
+ *
+ * In general it's possible to apply more than one directive to one element, but there might be limitations
+ * depending on the type of scope required by the directives. The following points will help explain these limitations.
+ * For simplicity only two directives are taken into account, but it is also applicable for several directives:
+ *
+ * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
+ * * **child scope** + **no scope** => Both directives will share one single child scope
+ * * **child scope** + **child scope** => Both directives will share one single child scope
+ * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use
+ * its parent's scope
+ * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
+ * be applied to the same element.
+ * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives
+ * cannot be applied to the same element.
+ *
+ *
+ * #### `bindToController`
+ * This property is used to bind scope properties directly to the controller. It can be either
+ * `true` or an object hash with the same format as the `scope` property. Additionally, a controller
+ * alias must be set, either by using `controllerAs: 'myAlias'` or by specifying the alias in the controller
+ * definition: `controller: 'myCtrl as myAlias'`.
+ *
+ * When an isolate scope is used for a directive (see above), `bindToController: true` will
+ * allow a component to have its properties bound to the controller, rather than to scope.
+ *
+ * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
+ * properties. You can access these bindings once they have been initialized by providing a controller method called
+ * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
+ * initialized.
+ *
+ * <div class="alert alert-warning">
+ * **Deprecation warning:** although bindings for non-ES6 class controllers are currently
+ * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization
+ * code that relies upon bindings inside a `$onInit` method on the controller, instead.
+ * </div>
+ *
+ * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
+ * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
+ * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
+ * scope (useful for component directives).
+ *
+ * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
+ *
+ *
+ * #### `controller`
+ * Controller constructor function. The controller is instantiated before the
+ * pre-linking phase and can be accessed by other directives (see
+ * `require` attribute). This allows the directives to communicate with each other and augment
+ * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
+ *
+ * * `$scope` - Current scope associated with the element
+ * * `$element` - Current element
+ * * `$attrs` - Current attributes object for the element
+ * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
+ * `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
+ * * `scope`: (optional) override the scope.
+ * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
+ * * `futureParentElement` (optional):
+ * * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
+ * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
+ * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
+ * and when the `cloneLinkinFn` is passed,
+ * as those elements need to created and cloned in a special way when they are defined outside their
+ * usual containers (e.g. like `<svg>`).
+ * * See also the `directive.templateNamespace` property.
+ * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
+ * then the default translusion is provided.
+ * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
+ * `true` if the specified slot contains content (i.e. one or more DOM nodes).
+ *
+ * #### `require`
+ * Require another directive and inject its controller as the fourth argument to the linking function. The
+ * `require` property can be a string, an array or an object:
+ * * a **string** containing the name of the directive to pass to the linking function
+ * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
+ * linking function will be an array of controllers in the same order as the names in the `require` property
+ * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
+ * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
+ * controllers.
+ *
+ * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
+ * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
+ * have been constructed but before `$onInit` is called.
+ * If the name of the required controller is the same as the local name (the key), the name can be
+ * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
+ * See the {@link $compileProvider#component} helper for an example of how this can be used.
+ * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
+ * raised (unless no link function is specified and the required controllers are not being bound to the directive
+ * controller, in which case error checking is skipped). The name can be prefixed with:
+ *
+ * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
+ * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
+ * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
+ * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
+ * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
+ * `null` to the `link` fn if not found.
+ * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
+ * `null` to the `link` fn if not found.
+ *
+ *
+ * #### `controllerAs`
+ * Identifier name for a reference to the controller in the directive's scope.
+ * This allows the controller to be referenced from the directive template. This is especially
+ * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
+ * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
+ * `controllerAs` reference might overwrite a property that already exists on the parent scope.
+ *
+ *
+ * #### `restrict`
+ * String of subset of `EACM` which restricts the directive to a specific directive
+ * declaration style. If omitted, the defaults (elements and attributes) are used.
+ *
+ * * `E` - Element name (default): `<my-directive></my-directive>`
+ * * `A` - Attribute (default): `<div my-directive="exp"></div>`
+ * * `C` - Class: `<div class="my-directive: exp;"></div>`
+ * * `M` - Comment: `<!-- directive: my-directive exp -->`
+ *
+ *
+ * #### `templateNamespace`
+ * String representing the document type used by the markup in the template.
+ * AngularJS needs this information as those elements need to be created and cloned
+ * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
+ *
+ * * `html` - All root nodes in the template are HTML. Root nodes may also be
+ * top-level elements such as `<svg>` or `<math>`.
+ * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
+ * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
+ *
+ * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
+ *
+ * #### `template`
+ * HTML markup that may:
+ * * Replace the contents of the directive's element (default).
+ * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
+ * * Wrap the contents of the directive's element (if `transclude` is true).
+ *
+ * Value may be:
+ *
+ * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
+ * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
+ * function api below) and returns a string value.
+ *
+ *
+ * #### `templateUrl`
+ * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
+ *
+ * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
+ * for later when the template has been resolved. In the meantime it will continue to compile and link
+ * sibling and parent elements as though this element had not contained any directives.
+ *
+ * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
+ * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
+ * case when only one deeply nested directive has `templateUrl`.
+ *
+ * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
+ *
+ * You can specify `templateUrl` as a string representing the URL or as a function which takes two
+ * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
+ * a string value representing the url. In either case, the template URL is passed through {@link
+ * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
+ *
+ *
+ * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
+ * specify what the template should replace. Defaults to `false`.
+ *
+ * * `true` - the template will replace the directive's element.
+ * * `false` - the template will replace the contents of the directive's element.
+ *
+ * The replacement process migrates all of the attributes / classes from the old element to the new
+ * one. See the {@link guide/directive#template-expanding-directive
+ * Directives Guide} for an example.
+ *
+ * There are very few scenarios where element replacement is required for the application function,
+ * the main one being reusable custom components that are used within SVG contexts
+ * (because SVG doesn't work with custom elements in the DOM tree).
+ *
+ * #### `transclude`
+ * Extract the contents of the element where the directive appears and make it available to the directive.
+ * The contents are compiled and provided to the directive as a **transclusion function**. See the
+ * {@link $compile#transclusion Transclusion} section below.
+ *
+ *
+ * #### `compile`
+ *
+ * ```js
+ * function compile(tElement, tAttrs, transclude) { ... }
+ * ```
+ *
+ * The compile function deals with transforming the template DOM. Since most directives do not do
+ * template transformation, it is not used often. The compile function takes the following arguments:
+ *
+ * * `tElement` - template element - The element where the directive has been declared. It is
+ * safe to do template transformation on the element and child elements only.
+ *
+ * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
+ * between all directive compile functions.
+ *
+ * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
+ *
+ * <div class="alert alert-warning">
+ * **Note:** The template instance and the link instance may be different objects if the template has
+ * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
+ * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
+ * should be done in a linking function rather than in a compile function.
+ * </div>
+
+ * <div class="alert alert-warning">
+ * **Note:** The compile function cannot handle directives that recursively use themselves in their
+ * own templates or compile functions. Compiling these directives results in an infinite loop and
+ * stack overflow errors.
+ *
+ * This can be avoided by manually using $compile in the postLink function to imperatively compile
+ * a directive's template instead of relying on automatic template compilation via `template` or
+ * `templateUrl` declaration or manual compilation inside the compile function.
+ * </div>
+ *
+ * <div class="alert alert-danger">
+ * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
+ * e.g. does not know about the right outer scope. Please use the transclude function that is passed
+ * to the link function instead.
+ * </div>
+
+ * A compile function can have a return value which can be either a function or an object.
+ *
+ * * returning a (post-link) function - is equivalent to registering the linking function via the
+ * `link` property of the config object when the compile function is empty.
+ *
+ * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
+ * control when a linking function should be called during the linking phase. See info about
+ * pre-linking and post-linking functions below.
+ *
+ *
+ * #### `link`
+ * This property is used only if the `compile` property is not defined.
+ *
+ * ```js
+ * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
+ * ```
+ *
+ * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
+ * executed after the template has been cloned. This is where most of the directive logic will be
+ * put.
+ *
+ * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
+ * directive for registering {@link ng.$rootScope.Scope#$watch watches}.
+ *
+ * * `iElement` - instance element - The element where the directive is to be used. It is safe to
+ * manipulate the children of the element only in `postLink` function since the children have
+ * already been linked.
+ *
+ * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
+ * between all directive linking functions.
+ *
+ * * `controller` - the directive's required controller instance(s) - Instances are shared
+ * among all directives, which allows the directives to use the controllers as a communication
+ * channel. The exact value depends on the directive's `require` property:
+ * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
+ * * `string`: the controller instance
+ * * `array`: array of controller instances
+ *
+ * If a required controller cannot be found, and it is optional, the instance is `null`,
+ * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
+ *
+ * Note that you can also require the directive's own controller - it will be made available like
+ * any other controller.
+ *
+ * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
+ * This is the same as the `$transclude` parameter of directive controllers,
+ * see {@link ng.$compile#-controller- the controller section for details}.
+ * `function([scope], cloneLinkingFn, futureParentElement)`.
+ *
+ * #### Pre-linking function
+ *
+ * Executed before the child elements are linked. Not safe to do DOM transformation since the
+ * compiler linking function will fail to locate the correct elements for linking.
+ *
+ * #### Post-linking function
+ *
+ * Executed after the child elements are linked.
+ *
+ * Note that child elements that contain `templateUrl` directives will not have been compiled
+ * and linked since they are waiting for their template to load asynchronously and their own
+ * compilation and linking has been suspended until that occurs.
+ *
+ * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
+ * for their async templates to be resolved.
+ *
+ *
+ * ### Transclusion
+ *
+ * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
+ * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
+ * scope from where they were taken.
+ *
+ * Transclusion is used (often with {@link ngTransclude}) to insert the
+ * original contents of a directive's element into a specified place in the template of the directive.
+ * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
+ * content has access to the properties on the scope from which it was taken, even if the directive
+ * has isolated scope.
+ * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
+ *
+ * This makes it possible for the widget to have private state for its template, while the transcluded
+ * content has access to its originating scope.
+ *
+ * <div class="alert alert-warning">
+ * **Note:** When testing an element transclude directive you must not place the directive at the root of the
+ * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
+ * Testing Transclusion Directives}.
+ * </div>
+ *
+ * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
+ * directive's element, the entire element or multiple parts of the element contents:
+ *
+ * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
+ * * `'element'` - transclude the whole of the directive's element including any directives on this
+ * element that defined at a lower priority than this directive. When used, the `template`
+ * property is ignored.
+ * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
+ *
+ * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
+ *
+ * This object is a map where the keys are the name of the slot to fill and the value is an element selector
+ * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
+ * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
+ *
+ * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
+ *
+ * If the element selector is prefixed with a `?` then that slot is optional.
+ *
+ * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to
+ * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
+ *
+ * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
+ * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
+ * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
+ * injectable into the directive's controller.
+ *
+ *
+ * #### Transclusion Functions
+ *
+ * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
+ * function** to the directive's `link` function and `controller`. This transclusion function is a special
+ * **linking function** that will return the compiled contents linked to a new transclusion scope.
+ *
+ * <div class="alert alert-info">
+ * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
+ * ngTransclude will deal with it for us.
+ * </div>
+ *
+ * If you want to manually control the insertion and removal of the transcluded content in your directive
+ * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
+ * object that contains the compiled DOM, which is linked to the correct transclusion scope.
+ *
+ * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
+ * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
+ * content and the `scope` is the newly created transclusion scope, to which the clone is bound.
+ *
+ * <div class="alert alert-info">
+ * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
+ * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
+ * </div>
+ *
+ * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
+ * attach function**:
+ *
+ * ```js
+ * var transcludedContent, transclusionScope;
+ *
+ * $transclude(function(clone, scope) {
+ * element.append(clone);
+ * transcludedContent = clone;
+ * transclusionScope = scope;
+ * });
+ * ```
+ *
+ * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
+ * associated transclusion scope:
+ *
+ * ```js
+ * transcludedContent.remove();
+ * transclusionScope.$destroy();
+ * ```
+ *
+ * <div class="alert alert-info">
+ * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
+ * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
+ * then you are also responsible for calling `$destroy` on the transclusion scope.
+ * </div>
+ *
+ * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
+ * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
+ * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
+ *
+ *
+ * #### Transclusion Scopes
+ *
+ * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
+ * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
+ * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
+ * was taken.
+ *
+ * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
+ * like this:
+ *
+ * ```html
+ * <div ng-app>
+ * <div isolate>
+ * <div transclusion>
+ * </div>
+ * </div>
+ * </div>
+ * ```
+ *
+ * The `$parent` scope hierarchy will look like this:
+ *
+ ```
+ - $rootScope
+ - isolate
+ - transclusion
+ ```
+ *
+ * but the scopes will inherit prototypically from different scopes to their `$parent`.
+ *
+ ```
+ - $rootScope
+ - transclusion
+ - isolate
+ ```
+ *
+ *
+ * ### Attributes
+ *
+ * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
+ * `link()` or `compile()` functions. It has a variety of uses.
+ *
+ * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
+ * 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
+ * to the attributes.
+ *
+ * * *Directive inter-communication:* All directives share the same instance of the attributes
+ * object which allows the directives to use the attributes object as inter directive
+ * communication.
+ *
+ * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
+ * allowing other directives to read the interpolated value.
+ *
+ * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
+ * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
+ * the only way to easily get the actual value because during the linking phase the interpolation
+ * hasn't been evaluated yet and so the value is at this time set to `undefined`.
+ *
+ * ```js
+ * function linkingFn(scope, elm, attrs, ctrl) {
+ * // get the attribute value
+ * console.log(attrs.ngModel);
+ *
+ * // change the attribute
+ * attrs.$set('ngModel', 'new value');
+ *
+ * // observe changes to interpolated attribute
+ * attrs.$observe('ngModel', function(value) {
+ * console.log('ngModel has changed value to ' + value);
+ * });
+ * }
+ * ```
+ *
+ * ## Example
+ *
+ * <div class="alert alert-warning">
+ * **Note**: Typically directives are registered with `module.directive`. The example below is
+ * to illustrate how `$compile` works.
+ * </div>
+ *
+ <example module="compileExample">
+ <file name="index.html">

+ $compileProvider.directive('compile', function($compile) {
+ // directive factory creates a link function
+ return function(scope, element, attrs) {
+ scope.$watch(
+ function(scope) {
+ // watch the 'compile' expression for changes
+ return scope.$eval(attrs.compile);
+ },
+ function(value) {
+ // when the 'compile' expression changes
+ // assign it into the current DOM
+ element.html(value);
+
+ // compile the new DOM and link it to the current
+ // scope.
+ // NOTE: we only compile .childNodes so that
+ // we don't get into infinite loop compiling ourselves
+ $compile(element.contents())(scope);
+ }
+ );
+ };
+ });
+ })
+ .controller('GreeterController', ['$scope', function($scope) {
+ $scope.name = 'Angular';
+ $scope.html = 'Hello {{name}}';
+ }]);
+ </script>
+ <div ng-controller="GreeterController">

+ </example>

+ * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
+ * e.g. will not use the right outer scope. Please pass the transclude function as a
+ * `parentBoundTranscludeFn` to the link function instead.
+ * </div>
+ *
+ * @param {number} maxPriority only apply directives lower than given priority (Only effects the

+ * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
+ * (a DOM element/tree) to a scope. Where:
+ *
+ * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+ * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+ * `template` and call the `cloneAttachFn` function allowing the caller to attach the
+ * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+ * called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
+ *
+ * * `clonedElement` - is a clone of the original `element` passed into the compiler.
+ * * `scope` - is the current scope with which the linking function is working with.
+ *
+ * * `options` - An optional object hash with linking options. If `options` is provided, then the following
+ * keys may be used to control linking behavior:
+ *
+ * * `parentBoundTranscludeFn` - the transclude function made available to
+ * directives; if given, it will be passed through to the link functions of
+ * directives found in `element` during compilation.
+ * * `transcludeControllers` - an object hash with keys that map controller names
+ * to a hash with the key `instance`, which maps to the controller instance;
+ * if given, it will make the controllers available to directives on the compileNode:
+ * ```
+ * {
+ * parent: {
+ * instance: parentControllerInstance
+ * }
+ * }
+ * ```
+ * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
+ * the cloned elements; only needed for transcludes that are allowed to contain non html
+ * elements (e.g. SVG elements). See also the directive.controller property.
+ *
+ * Calling the linking function returns the element of the template. It is either the original
+ * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
+ *
+ * After linking the view is not updated until after a call to $digest which typically is done by
+ * Angular automatically.
+ *
+ * If you need access to the bound view, there are two ways to do it:
+ *
+ * - If you are not asking the linking function to clone the template, create the DOM element(s)
+ * before you send them to the compiler and keep this reference around.
+ * ```js
+ * var element = $compile('<p>{{total}}</p>')(scope);
+ * ```
+ *
+ * - if on the other hand, you need the element to be cloned, the view reference from the original
+ * example would not point to the clone, but rather to the original template that was cloned. In
+ * this case, you can access the clone via the cloneAttachFn:
+ * ```js
+ * var templateElement = angular.element('<p>{{total}}</p>'),
+ * scope = ....;
+ *
+ * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
+ * //attach the clone to DOM document at the right place
+ * });
+ *
+ * //now we have reference to the cloned DOM via `clonedElement`
+ * ```
+ *
+ *

+ * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

+ * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
+ *
+ * Component definitions are very simple and do not require as much configuration as defining general
+ * directives. Component definitions usually consist only of a template and a controller backing it.
+ *
+ * In order to make the definition easier, components enforce best practices like use of `controllerAs`,

+ *
+ * @description
+ * The `$http` service is a core Angular service that facilitates communication with the remote
+ * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
+ * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
+ *
+ * For unit testing applications that use `$http` service, see
+ * {@link ngMock.$httpBackend $httpBackend mock}.
+ *
+ * For a higher level of abstraction, please check out the {@link ngResource.$resource
+ * $resource} service.
+ *
+ * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
+ * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
+ * it is important to familiarize yourself with these APIs and the guarantees they provide.
+ *
+ *
+ * ## General usage
+ * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
+ * that is used to generate an HTTP request and returns a {@link ng.$q promise}.
+ *
+ * ```js
+ * // Simple GET request example:
+ * $http({
+ * method: 'GET',
+ * url: '/someUrl'
+ * }).then(function successCallback(response) {
+ * // this callback will be called asynchronously
+ * // when the response is available
+ * }, function errorCallback(response) {
+ * // called asynchronously if an error occurs
+ * // or server returns response with an error status.
+ * });
+ * ```
+ *
+ * The response object has these properties:
+ *
+ * - **data** – `{string|Object}` – The response body transformed with the transform
+ * functions.
+ * - **status** – `{number}` – HTTP status code of the response.
+ * - **headers** – `{function([headerName])}` – Header getter function.
+ * - **config** – `{Object}` – The configuration object that was used to generate the request.
+ * - **statusText** – `{string}` – HTTP status text of the response.
+ *
+ * A response status code between 200 and 299 is considered a success status and will result in
+ * the success callback being called. Any response status code outside of that range is
+ * considered an error status and will result in the error callback being called.
+ * Also, status codes less than -1 are normalized to zero. -1 usually means the request was
+ * aborted, e.g. using a `config.timeout`.
+ * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning
+ * that the outcome (success or error) will be determined by the final response status code.
+ *
+ *
+ * ## Shortcut methods
+ *
+ * Shortcut methods are also available. All shortcut methods require passing in the URL, and
+ * request data must be passed in for POST/PUT requests. An optional config can be passed as the
+ * last argument.
+ *
+ * ```js
+ * $http.get('/someUrl', config).then(successCallback, errorCallback);
+ * $http.post('/someUrl', data, config).then(successCallback, errorCallback);
+ * ```
+ *
+ * Complete list of shortcut methods:
+ *
+ * - {@link ng.$http#get $http.get}
+ * - {@link ng.$http#head $http.head}
+ * - {@link ng.$http#post $http.post}
+ * - {@link ng.$http#put $http.put}
+ * - {@link ng.$http#delete $http.delete}
+ * - {@link ng.$http#jsonp $http.jsonp}
+ * - {@link ng.$http#patch $http.patch}
+ *
+ *
+ * ## Writing Unit Tests that use $http
+ * When unit testing (using {@link ngMock ngMock}), it is necessary to call
+ * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
+ * request using trained responses.
+ *
+ * ```
+ * $httpBackend.expectGET(...);
+ * $http.get(...);
+ * $httpBackend.flush();
+ * ```
+ *
+ * ## Deprecation Notice
+ * <div class="alert alert-danger">
+ * The `$http` legacy promise methods `success` and `error` have been deprecated.
+ * Use the standard `then` method instead.
+ * If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to
+ * `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.
+ * </div>
+ *
+ * ## Setting HTTP Headers
+ *
+ * The $http service will automatically add certain HTTP headers to all requests. These defaults
+ * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+ * object, which currently contains this default configuration:
+ *
+ * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+ * - `Accept: application/json, text/plain, * / *`
+ * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
+ * - `Content-Type: application/json`
+ * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
+ * - `Content-Type: application/json`
+ *
+ * To add or overwrite these defaults, simply add or remove a property from these configuration
+ * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+ * with the lowercased HTTP method name as the key, e.g.
+ * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
+ *
+ * The defaults can also be set at runtime via the `$http.defaults` object in the same
+ * fashion. For example:
+ *
+ * ```
+ * module.run(function($http) {
+ * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
+ * });
+ * ```
+ *
+ * In addition, you can supply a `headers` property in the config object passed when
+ * calling `$http(config)`, which overrides the defaults without changing them globally.
+ *
+ * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
+ * Use the `headers` property, setting the desired header to `undefined`. For example:
+ *
+ * ```js
+ * var req = {
+ * method: 'POST',
+ * url: 'http://example.com',
+ * headers: {
+ * 'Content-Type': undefined
+ * },
+ * data: { test: 'test' }
+ * }
+ *
+ * $http(req).then(function(){...}, function(){...});
+ * ```
+ *
+ * ## Transforming Requests and Responses
+ *
+ * Both requests and responses can be transformed using transformation functions: `transformRequest`
+ * and `transformResponse`. These properties can be a single function that returns
+ * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
+ * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
+ *
+ * <div class="alert alert-warning">
+ * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
+ * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
+ * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
+ * function will be reflected on the scope and in any templates where the object is data-bound.
+ * To prevent this, transform functions should have no side-effects.
+ * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
+ * </div>
+ *
+ * ### Default Transformations
+ *
+ * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
+ * `defaults.transformResponse` properties. If a request does not provide its own transformations
+ * then these will be applied.
+ *
+ * You can augment or replace the default transformations by modifying these properties by adding to or
+ * replacing the array.
+ *
+ * Angular provides the following default transformations:
+ *
+ * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
+ *
+ * - If the `data` property of the request configuration object contains an object, serialize it
+ * into JSON format.
+ *
+ * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
+ *
+ * - If XSRF prefix is detected, strip it (see Security Considerations section below).
+ * - If JSON response is detected, deserialize it using a JSON parser.
+ *
+ *
+ * ### Overriding the Default Transformations Per Request
+ *
+ * If you wish to override the request/response transformations only for a single request then provide
+ * `transformRequest` and/or `transformResponse` properties on the configuration object passed
+ * into `$http`.
+ *
+ * Note that if you provide these properties on the config object the default transformations will be
+ * overwritten. If you wish to augment the default transformations then you must include them in your
+ * local transformation array.
+ *
+ * The following code demonstrates adding a new response transformation to be run after the default response
+ * transformations have been run.
+ *
+ * ```js
+ * function appendTransform(defaults, transform) {
+ *
+ * // We can't guarantee that the default transformation is an array
+ * defaults = angular.isArray(defaults) ? defaults : [defaults];
+ *
+ * // Append the new transformation to the defaults
+ * return defaults.concat(transform);
+ * }
+ *
+ * $http({
+ * url: '...',
+ * method: 'GET',
+ * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
+ * return doTransform(value);
+ * })
+ * });
+ * ```
+ *
+ *
+ * ## Caching
+ *
+ * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
+ * set the config.cache value or the default cache value to TRUE or to a cache object (created
+ * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
+ * precedence over the default cache value.
+ *
+ * In order to:
+ * * cache all responses - set the default cache value to TRUE or to a cache object
+ * * cache a specific response - set config.cache value to TRUE or to a cache object
+ *
+ * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
+ * then the default `$cacheFactory("$http")` object is used.
+ *
+ * The default cache value can be set by updating the
+ * {@link ng.$http#defaults `$http.defaults.cache`} property or the
+ * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
+ *
+ * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
+ * the relevant cache object. The next time the same request is made, the response is returned
+ * from the cache without sending a request to the server.
+ *
+ * Take note that:
+ *
+ * * Only GET and JSONP requests are cached.
+ * * The cache key is the request URL including search parameters; headers are not considered.
+ * * Cached responses are returned asynchronously, in the same way as responses from the server.
+ * * If multiple identical requests are made using the same cache, which is not yet populated,
+ * one request will be made to the server and remaining requests will return the same response.
+ * * A cache-control header on the response does not affect if or how responses are cached.
+ *
+ *
+ * ## Interceptors
+ *
+ * Before you start creating interceptors, be sure to understand the
+ * {@link ng.$q $q and deferred/promise APIs}.
+ *
+ * For purposes of global error handling, authentication, or any kind of synchronous or
+ * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
+ * able to intercept requests before they are handed to the server and
+ * responses before they are handed over to the application code that
+ * initiated these requests. The interceptors leverage the {@link ng.$q
+ * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
+ *
+ * The interceptors are service factories that are registered with the `$httpProvider` by
+ * adding them to the `$httpProvider.interceptors` array. The factory is called and
+ * injected with dependencies (if specified) and returns the interceptor.
+ *
+ * There are two kinds of interceptors (and two kinds of rejection interceptors):
+ *
+ * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
+ * modify the `config` object or create a new one. The function needs to return the `config`
+ * object directly, or a promise containing the `config` or a new `config` object.
+ * * `requestError`: interceptor gets called when a previous interceptor threw an error or
+ * resolved with a rejection.
+ * * `response`: interceptors get called with http `response` object. The function is free to
+ * modify the `response` object or create a new one. The function needs to return the `response`
+ * object directly, or as a promise containing the `response` or a new `response` object.
+ * * `responseError`: interceptor gets called when a previous interceptor threw an error or
+ * resolved with a rejection.
+ *
+ *
+ * ```js
+ * // register the interceptor as a service
+ * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+ * return {
+ * // optional method
+ * 'request': function(config) {
+ * // do something on success
+ * return config;
+ * },
+ *
+ * // optional method
+ * 'requestError': function(rejection) {
+ * // do something on error
+ * if (canRecover(rejection)) {
+ * return responseOrNewPromise
+ * }
+ * return $q.reject(rejection);
+ * },
+ *
+ *
+ *
+ * // optional method
+ * 'response': function(response) {
+ * // do something on success
+ * return response;
+ * },
+ *
+ * // optional method
+ * 'responseError': function(rejection) {
+ * // do something on error
+ * if (canRecover(rejection)) {
+ * return responseOrNewPromise
+ * }
+ * return $q.reject(rejection);
+ * }
+ * };
+ * });
+ *
+ * $httpProvider.interceptors.push('myHttpInterceptor');
+ *
+ *
+ * // alternatively, register the interceptor via an anonymous factory
+ * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
+ * return {
+ * 'request': function(config) {
+ * // same as above
+ * },
+ *
+ * 'response': function(response) {
+ * // same as above
+ * }
+ * };
+ * });
+ * ```
+ *
+ * ## Security Considerations
+ *
+ * When designing web applications, consider security threats from:
+ *
+ * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+ * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
+ *
+ * Both server and the client must cooperate in order to eliminate these threats. Angular comes
+ * pre-configured with strategies that address these issues, but for this to work backend server
+ * cooperation is required.
+ *
+ * ### JSON Vulnerability Protection
+ *
+ * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+ * allows third party website to turn your JSON resource URL into
+ * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
+ * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+ * Angular will automatically strip the prefix before processing it as JSON.
+ *
+ * For example if your server needs to return:
+ * ```js
+ * ['one','two']
+ * ```
+ *
+ * which is vulnerable to attack, your server can return:
+ * ```js
+ * )]}',
+ * ['one','two']
+ * ```
+ *
+ * Angular will strip the prefix, before processing the JSON.
+ *
+ *
+ * ### Cross Site Request Forgery (XSRF) Protection
+ *
+ * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
+ * which the attacker can trick an authenticated user into unknowingly executing actions on your
+ * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
+ * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
+ * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
+ * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
+ * The header will not be set for cross-domain requests.
+ *
+ * To take advantage of this, your server needs to set a token in a JavaScript readable session
+ * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
+ * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
+ * that only JavaScript running on your domain could have sent the request. The token must be
+ * unique for each user and must be verifiable by the server (to prevent the JavaScript from
+ * making up its own tokens). We recommend that the token is a digest of your site's
+ * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
+ * for added security.
+ *
+ * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
+ * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
+ * or the per-request config object.
+ *
+ * In order to prevent collisions in environments where multiple Angular apps share the
+ * same domain or subdomain, we recommend that each application uses unique cookie name.
+ *
+ * @param {object} config Object describing the request to be made and how it should be
+ * processed. The object has following properties:
+ *
+ * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+ * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
+ * - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
+ * with the `paramSerializer` and appended as GET parameters.
+ * - **data** – `{string|Object}` – Data to be sent as the request message data.
+ * - **headers** – `{Object}` – Map of strings or functions which return strings representing
+ * HTTP headers to send to the server. If the return value of a function is null, the
+ * header will not be sent. Functions accept a config object as an argument.
+ * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
+ * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
+ * The handler will be called in the context of a `$apply` block.
+ * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
+ * object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
+ * The handler will be called in the context of a `$apply` block.
+ * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
+ * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
+ * - **transformRequest** –
+ * `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+ * transform function or an array of such functions. The transform function takes the http
+ * request body and headers and returns its transformed (typically serialized) version.
+ * See {@link ng.$http#overriding-the-default-transformations-per-request
+ * Overriding the Default Transformations}
+ * - **transformResponse** –
+ * `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
+ * transform function or an array of such functions. The transform function takes the http
+ * response body, headers and status and returns its transformed (typically deserialized) version.
+ * See {@link ng.$http#overriding-the-default-transformations-per-request
+ * Overriding the Default Transformations}
+ * - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
+ * prepare the string representation of request parameters (specified as an object).
+ * If specified as string, it is interpreted as function registered with the
+ * {@link $injector $injector}, which means you can create your own serializer
+ * by registering it as a {@link auto.$provide#service service}.
+ * The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
+ * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
+ * - **cache** – `{boolean|Object}` – A boolean value or object created with
+ * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
+ * See {@link $http#caching $http Caching} for more information.
+ * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
+ * that should abort the request when resolved.
+ * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
+ * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
+ * for more information.
+ * - **responseType** - `{string}` - see
+ * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
+ *
+ * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
+ * when the request succeeds or fails.
+ *
+ *
+ * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
+ * requests. This is primarily meant to be used for debugging purposes.

+ * @description
+ *
+ * Compiles a string with markup into an interpolation function. This service is used by the
+ * HTML {@link ng.$compile $compile} service for data binding. See
+ * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
+ * interpolation markup.
+ *
+ *
+ * ```js
+ * var $interpolate = ...; // injected
+ * var exp = $interpolate('Hello {{name | uppercase}}!');
+ * expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
+ * ```
+ *
+ * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
+ * `true`, the interpolation function will return `undefined` unless all embedded expressions
+ * evaluate to a value other than `undefined`.
+ *
+ * ```js
+ * var $interpolate = ...; // injected
+ * var context = {greeting: 'Hello', name: undefined };
+ *
+ * // default "forgiving" mode
+ * var exp = $interpolate('{{greeting}} {{name}}!');
+ * expect(exp(context)).toEqual('Hello !');

+ * exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
+ * expect(exp(context)).toBeUndefined();
+ * context.name = 'Angular';
+ * expect(exp(context)).toEqual('Hello Angular!');
+ * ```
+ *
+ * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
+ *
+ * #### Escaped Interpolation
+ * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
+ * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
+ * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
+ * or binding.
+ *
+ * This enables web-servers to prevent script injection attacks and defacing attacks, to some
+ * degree, while also enabling code examples to work without relying on the
+ * {@link ng.directive:ngNonBindable ngNonBindable} directive.
+ *
+ * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
+ * replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all
+ * interpolation start/end markers with their escaped counterparts.**
+ *
+ * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
+ * output when the $interpolate service processes the text. So, for HTML elements interpolated
+ * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
+ * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
+ * this is typically useful only when user-data is used in rendering a template from the server, or
+ * when otherwise untrusted data is used by a directive.
+ *
+ * <example>
+ * <file name="index.html">
+ * <div ng-init="username='A user'">
+ * <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
+ * </p>
+ * <p><strong>{{username}}</strong> attempts to inject code which will deface the
+ * application, but fails to accomplish their task, because the server has correctly
+ * escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
+ * characters.</p>
+ * <p>Instead, the result of the attempted script injection is visible, and can be removed
+ * from the database by an administrator.</p>
+ * </div>
+ * </file>
+ * </example>
+ *
+ * @knownIssue
+ * It is currently not possible for an interpolated expression to contain the interpolation end
+ * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
+ * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
+ *
+ * @knownIssue
+ * All directives and components must use the standard `{{` `}}` interpolation symbols
+ * in their templates. If you change the application interpolation symbols the {@link $compile}
+ * service will attempt to denormalize the standard symbols to the custom symbols.
+ * The denormalization process is not clever enough to know not to replace instances of the standard
+ * symbols where they would not normally be treated as interpolation symbols. For example in the following
+ * code snippet the closing braces of the literal object will get incorrectly denormalized:
+ *
+ * ```
+ * <div data-context='{"context":{"id":3,"type":"page"}}">
+ * ```
+ *
+ * The workaround is to ensure that such instances are separated by whitespace:
+ * ```
+ * <div data-context='{"context":{"id":3,"type":"page"} }">

+ * @description
+ * Angular's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
+ * milliseconds.
+ *
+ * The return value of registering an interval function is a promise. This promise will be
+ * notified upon each tick of the interval, and will be resolved after `count` iterations, or
+ * run indefinitely if `count` is not defined. The value of the notification will be the
+ * number of iterations that have run.
+ * To cancel an interval, call `$interval.cancel(promise)`.
+ *
+ * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
+ * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
+ * time.
+ *
+ * <div class="alert alert-warning">
+ * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
+ * with them. In particular they are not automatically destroyed when a controller's scope or a
+ * directive's element are destroyed.
+ * You should take this into consideration and make sure to always cancel the interval at the
+ * appropriate moment. See the example below for more details on how and when to do this.
+ * </div>
+ *
+ * @param {function()} fn A function that should be called repeatedly.
+ * @param {number} delay Number of milliseconds between each function call.
+ * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
+ * indefinitely.
+ * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
+ * will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
+ * @param {...*=} Pass additional parameters to the executed function.
+ * @returns {promise} A promise which will be notified on each iteration.

+// obtaining a reference to native JS functions such as the Function constructor.
+//
+// As an example, consider the following Angular expression:

+// {}.toString.constructor('alert("evil JS code")')
+//
+// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
+// against the expression language, but not to prevent exploits that were enabled by exposing
+// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
+// practice and therefore we are not even trying to protect against interaction with an object
+// explicitly exposed in this way.
+//
+// In general, it is not possible to access a Window object from an angular expression unless a
+// window or some DOM object that has a reference to window is published onto a Scope.
+// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
+// native objects.

+/**
+ * @ngdoc service
+ * @name $q
+ * @requires $rootScope
+ *
+ * @description
+ * A service that helps you run functions asynchronously, and use their return values (or exceptions)
+ * when they are done processing.
+ *
+ * This is an implementation of promises/deferred objects inspired by
+ * [Kris Kowal's Q](https://github.com/kriskowal/q).
+ *
+ * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
+ * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
+ *
+ * # $q constructor
+ *
+ * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
+ * function as the first argument. This is similar to the native Promise implementation from ES6,
+ * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
+ *
+ * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
+ * available yet.
+ *
+ * It can be used like so:
+ *
+ * ```js
+ * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+ * // are available in the current lexical scope (they could have been injected or passed in).
+ *
+ * function asyncGreet(name) {
+ * // perform some asynchronous operation, resolve or reject the promise when appropriate.
+ * return $q(function(resolve, reject) {
+ * setTimeout(function() {
+ * if (okToGreet(name)) {
+ * resolve('Hello, ' + name + '!');
+ * } else {
+ * reject('Greeting ' + name + ' is not allowed.');
+ * }
+ * }, 1000);
+ * });
+ * }
+ *
+ * var promise = asyncGreet('Robin Hood');
+ * promise.then(function(greeting) {
+ * alert('Success: ' + greeting);
+ * }, function(reason) {
+ * alert('Failed: ' + reason);
+ * });
+ * ```
+ *
+ * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
+ *
+ * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
+ *
+ * However, the more traditional CommonJS-style usage is still available, and documented below.
+ *
+ * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
+ * interface for interacting with an object that represents the result of an action that is
+ * performed asynchronously, and may or may not be finished at any given point in time.
+ *
+ * From the perspective of dealing with error handling, deferred and promise APIs are to
+ * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
+ *
+ * ```js
+ * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+ * // are available in the current lexical scope (they could have been injected or passed in).
+ *
+ * function asyncGreet(name) {
+ * var deferred = $q.defer();
+ *
+ * setTimeout(function() {
+ * deferred.notify('About to greet ' + name + '.');
+ *
+ * if (okToGreet(name)) {
+ * deferred.resolve('Hello, ' + name + '!');
+ * } else {
+ * deferred.reject('Greeting ' + name + ' is not allowed.');
+ * }
+ * }, 1000);
+ *
+ * return deferred.promise;
+ * }
+ *
+ * var promise = asyncGreet('Robin Hood');
+ * promise.then(function(greeting) {
+ * alert('Success: ' + greeting);
+ * }, function(reason) {
+ * alert('Failed: ' + reason);
+ * }, function(update) {
+ * alert('Got notification: ' + update);
+ * });
+ * ```
+ *
+ * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
+ * comes in the way of guarantees that promise and deferred APIs make, see
+ * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
+ *
+ * Additionally the promise api allows for composition that is very hard to do with the
+ * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
+ * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
+ * section on serial or parallel joining of promises.
+ *
+ * # The Deferred API
+ *
+ * A new instance of deferred is constructed by calling `$q.defer()`.
+ *
+ * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
+ * that can be used for signaling the successful or unsuccessful completion, as well as the status
+ * of the task.
+ *
+ * **Methods**
+ *
+ * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
+ * constructed via `$q.reject`, the promise will be rejected instead.
+ * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
+ * resolving it with a rejection constructed via `$q.reject`.
+ * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
+ * multiple times before the promise is either resolved or rejected.
+ *
+ * **Properties**
+ *
+ * - promise – `{Promise}` – promise object associated with this deferred.
+ *
+ *
+ * # The Promise API
+ *
+ * A new promise instance is created when a deferred instance is created and can be retrieved by
+ * calling `deferred.promise`.
+ *
+ * The purpose of the promise object is to allow for interested parties to get access to the result
+ * of the deferred task when it completes.
+ *
+ * **Methods**
+ *
+ * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
+ * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
+ * as soon as the result is available. The callbacks are called with a single argument: the result
+ * or rejection reason. Additionally, the notify callback may be called zero or more times to
+ * provide a progress indication, before the promise is resolved or rejected.
+ *
+ * This method *returns a new promise* which is resolved or rejected via the return value of the
+ * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
+ * with the value which is resolved in that promise using
+ * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
+ * It also notifies via the return value of the `notifyCallback` method. The promise cannot be
+ * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
+ * arguments are optional.
+ *
+ * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
+ *
+ * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
+ * but to do so without modifying the final value. This is useful to release resources or do some
+ * clean-up that needs to be done whether the promise was rejected or resolved. See the [full
+ * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
+ * more information.
+ *
+ * # Chaining promises
+ *
+ * Because calling the `then` method of a promise returns a new derived promise, it is easily
+ * possible to create a chain of promises:
+ *
+ * ```js
+ * promiseB = promiseA.then(function(result) {
+ * return result + 1;
+ * });
+ *
+ * // promiseB will be resolved immediately after promiseA is resolved and its value
+ * // will be the result of promiseA incremented by 1
+ * ```
+ *
+ * It is possible to create chains of any length and since a promise can be resolved with another
+ * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+ * the promises at any point in the chain. This makes it possible to implement powerful APIs like
+ * $http's response interceptors.
+ *
+ *
+ * # Differences between Kris Kowal's Q and $q
+ *
+ * There are two main differences:
+ *
+ * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation

+ *
+ * The typical use of scope is to watch the expressions, which most of the time return the same
+ * value as last time so we optimize the operation.
+ *
+ * Closures construction is expensive in terms of speed as well as memory:
+ * - No closures, instead use prototypical inheritance for API
+ * - Internal state needs to be stored on scope directly, which means that private state is
+ * exposed as $$____ properties
+ *
+ * Loop operations are optimized by using while(count--) { ... }
+ * - This means that in order to keep the same order of execution as addition we have to add
+ * items to the array at the beginning (unshift) instead of at the end (push)
+ *
+ * Child scopes are created and removed often
+ * - Using an array would be slow since inserts in the middle are expensive; so we use linked lists
+ *
+ * There are fewer watches than observers. This is why you don't want the observer to be implemented
+ * in the same way as watch. Watch requires return of the initialization function which is expensive
+ * to construct.

+ * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
+ *
+ * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
+ * $digest()} and should return the value that will be watched. (`watchExpression` should not change
+ * its value when executed multiple times with the same input because it may be executed multiple
+ * times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
+ * [idempotent](http://en.wikipedia.org/wiki/Idempotence).
+ * - The `listener` is called only when the value from the current `watchExpression` and the
+ * previous call to `watchExpression` are not equal (with the exception of the initial run,
+ * see below). Inequality is determined according to reference inequality,
+ * [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
+ * via the `!==` Javascript operator, unless `objectEquality == true`
+ * (see next point)
+ * - When `objectEquality == true`, inequality of the `watchExpression` is determined
+ * according to the {@link angular.equals} function. To save the value of the object for
+ * later comparison, the {@link angular.copy} function is used. This therefore means that
+ * watching complex objects will have adverse memory and performance implications.
+ * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
+ * This is achieved by rerunning the watchers until no changes are detected. The rerun
+ * iteration limit is 10 to prevent an infinite loop deadlock.
+ *
+ *
+ * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
+ * you can register a `watchExpression` function with no `listener`. (Be prepared for
+ * multiple calls to your `watchExpression` because it will execute multiple times in a
+ * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
+ *
+ * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+ * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
+ * watcher. In rare cases, this is undesirable because the listener is called when the result
+ * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+ * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+ * listener was called due to initialization.
+ *
+ *
+ *
+ * # Example
+ * ```js
+ // let's assume that scope was dependency injected as the $rootScope
+ var scope = $rootScope;
+ scope.name = 'misko';

+
+ scope.$digest();

+ *
+ * # Strict Contextual Escaping
+ *
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
+ * contexts to result in a value that is marked as safe to use for that context. One example of
+ * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer
+ * to these contexts as privileged or SCE contexts.
+ *
+ * As of version 1.2, Angular ships with SCE enabled by default.
+ *
+ * Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow
+ * one to execute arbitrary javascript by the use of the expression() syntax. Refer
+ * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
+ * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
+ * to the top of your HTML document.
+ *
+ * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for
+ * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * Here's an example of a binding in a privileged context:
+ *
+ * ```
+ * <input ng-model="userHtml" aria-label="User input">
+ * <div ng-bind-html="userHtml"></div>
+ * ```
+ *
+ * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
+ * disabled, this application allows the user to render arbitrary HTML into the DIV.
+ * In a more realistic example, one may be rendering user comments, blog articles, etc. via
+ * bindings. (HTML is just one example of a context where rendering user controlled input creates
+ * security vulnerabilities.)
+ *
+ * For the case of HTML, you might use a library, either on the client side, or on the server side,
+ * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+ *
+ * How would you ensure that every place that used these types of bindings was bound to a value that
+ * was sanitized by your library (or returned as safe for rendering by your server?) How can you
+ * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+ * properties/fields and forgot to update the binding to the sanitized value?
+ *
+ * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
+ * determine that something explicitly says it's safe to use a value for binding in that
+ * context. You can then audit your code (a simple grep would do) to ensure that this is only done
+ * for those values that you can easily tell are safe - because they were received from your server,
+ * sanitized by your library, etc. You can organize your codebase to help with this - perhaps
+ * allowing only the files in a specific directory to do this. Ensuring that the internal API
+ * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
+ *
+ * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
+ * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
+ * obtain values that will be accepted by SCE / privileged contexts.
+ *
+ *
+ * ## How does it work?
+ *
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
+ * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link
+ * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
+ * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
+ *
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+ * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
+ * simplified):
+ *
+ * ```
+ * var ngBindHtmlDirective = ['$sce', function($sce) {
+ * return function(scope, element, attr) {
+ * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+ * element.html(value || '');
+ * });
+ * };
+ * }];
+ * ```
+ *
+ * ## Impact on loading templates
+ *
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+ * `templateUrl`'s specified by {@link guide/directive directives}.
+ *
+ * By default, Angular only loads templates from the same domain and protocol as the application
+ * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
+ * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
+ * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
+ *
+ * *Please note*:
+ * The browser's
+ * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
+ * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
+ * policy apply in addition to this and may further restrict whether the template is successfully
+ * loaded. This means that without the right CORS policy, loading templates from a different domain
+ * won't work on all browsers. Also, loading templates from `file://` URL does not work on some
+ * browsers.
+ *
+ * ## This feels like too much overhead
+ *
+ * It's important to remember that SCE only applies to interpolation expressions.
+ *
+ * If your expressions are constant literals, they're automatically trusted and you don't need to
+ * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
+ * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
+ *
+ * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
+ * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here.
+ *
+ * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
+ * templates in `ng-include` from your application's domain without having to even know about SCE.
+ * It blocks loading templates from other domains or loading templates over http from an https
+ * served document. You can change these by setting your own custom {@link
+ * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
+ * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
+ *
+ * This significantly reduces the overhead. It is far easier to pay the small overhead and have an
+ * application that's secure and can be audited to verify that with much more ease than bolting
+ * security onto an application later.
+ *
+ * <a name="contexts"></a>
+ * ## What trusted context types are supported?
+ *
+ * | Context | Notes |
+ * |---------------------|----------------|
+ * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
+ * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. |
+ * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. |
+ * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.) <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
+ * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. |
+ *
+ * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
+ *
+ * Each element in these arrays must be one of the following:
+ *
+ * - **'self'**
+ * - The special **string**, `'self'`, can be used to match against all URLs of the **same
+ * domain** as the application document using the **same protocol**.
+ * - **String** (except the special value `'self'`)
+ * - The string is matched against the full *normalized / absolute URL* of the resource
+ * being tested (substring matches are not good enough.)
+ * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters
+ * match themselves.
+ * - `*`: matches zero or more occurrences of any character other than one of the following 6
+ * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use
+ * in a whitelist.
+ * - `**`: matches zero or more occurrences of *any* character. As such, it's not
+ * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g.
+ * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
+ * not have been the intention.) Its usage at the very end of the path is ok. (e.g.
+ * http://foo.example.com/templates/**).
+ * - **RegExp** (*see caveat below*)
+ * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax
+ * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to
+ * accidentally introduce a bug when one updates a complex expression (imho, all regexes should
+ * have good test coverage). For instance, the use of `.` in the regex is correct only in a
+ * small number of cases. A `.` character in the regex used when matching the scheme or a
+ * subdomain could be matched against a `:` or literal `.` that was likely not intended. It
+ * is highly recommended to use the string patterns and only fall back to regular expressions
+ * as a last resort.
+ * - The regular expression must be an instance of RegExp (i.e. not a string.) It is
+ * matched against the **entire** *normalized / absolute URL* of the resource being tested
+ * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags
+ * present on the RegExp (such as multiline, global, ignoreCase) are ignored.
+ * - If you are generating your JavaScript from some other templating engine (not
+ * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
+ * remember to escape your regular expression (and be aware that you might need more than
+ * one level of escaping depending on your templating engine and the way you interpolated
+ * the value.) Do make use of your platform's escaping mechanism as it might be good
+ * enough before coding your own. E.g. Ruby has
+ * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
+ * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
+ * Javascript lacks a similar built in function for escaping. Take a look at Google
+ * Closure library's [goog.string.regExpEscape(s)](
+ * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
+ *

+ * ## Can I disable SCE completely?

+ * Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
+ * for little coding overhead. It will be much harder to take an SCE disabled application and
+ * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
+ * for cases where you have a lot of existing code that was written before SCE was introduced and
+ * you're migrating them a module at a time.
+ *
+ * That said, here's how you can completely disable SCE:
+ *
+ * ```
+ * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
+ * // Completely disable SCE. For demonstration purposes only!
+ * // Do not use in new projects.
+ * $sceProvider.enabled(false);
+ * });

+ /* Design notes on the default implementation for SCE.
+ *
+ * The API contract for the SCE delegate
+ * -------------------------------------
+ * The SCE delegate object must provide the following 3 methods:
+ *
+ * - trustAs(contextEnum, value)
+ * This method is used to tell the SCE service that the provided value is OK to use in the
+ * contexts specified by contextEnum. It must return an object that will be accepted by
+ * getTrusted() for a compatible contextEnum and return this value.
+ *
+ * - valueOf(value)
+ * For values that were not produced by trustAs(), return them as is. For values that were
+ * produced by trustAs(), return the corresponding input value to trustAs. Basically, if
+ * trustAs is wrapping the given values into some type, this operation unwraps it when given
+ * such a value.
+ *
+ * - getTrusted(contextEnum, value)
+ * This function should return the a value that is safe to use in the context specified by
+ * contextEnum or throw and exception otherwise.
+ *
+ * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
+ * opaque or wrapped in some holder object. That happens to be an implementation detail. For
+ * instance, an implementation could maintain a registry of all trusted objects by context. In
+ * such a case, trustAs() would return the same object that was passed in. getTrusted() would
+ * return the same object passed in if it was found in the registry under a compatible context or
+ * throw an exception otherwise. An implementation might only wrap values some of the time based
+ * on some criteria. getTrusted() might return a value and not throw an exception for special
+ * constants or objects even if not wrapped. All such implementations fulfill this contract.
+ *
+ *
+ * A note on the inheritance model for SCE contexts
+ * ------------------------------------------------
+ * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
+ * is purely an implementation details.
+ *
+ * The contract is simply this:
+ *
+ * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
+ * will also succeed.
+ *
+ * Inheritance happens to capture this in a natural way. In some future, we
+ * may not use inheritance anymore. That is OK because no code outside of
+ * sce.js and sceSpecs.js would need to be aware of this detail.

+ *
+ * Implementation Notes for non-IE browsers
+ * ----------------------------------------
+ * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
+ * results both in the normalizing and parsing of the URL. Normalizing means that a relative
+ * URL will be resolved into an absolute URL in the context of the application document.
+ * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
+ * properties are all populated to reflect the normalized URL. This approach has wide
+ * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See
+ * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
+ *
+ * Implementation Notes for IE
+ * ---------------------------
+ * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
+ * browsers. However, the parsed components will not be set if the URL assigned did not specify
+ * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
+ * work around that by performing the parsing in a 2nd step by taking a previously normalized
+ * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
+ * properties such as protocol, hostname, port, etc.

+/**
+ * @ngdoc filter
+ * @name filter
+ * @kind function
+ *
+ * @description
+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * @param {Array} array The source array.
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ * `array`.
+ *
+ * Can be one of:
+ *
+ * - `string`: The string is used for matching against the contents of the `array`. All strings or
+ * objects with string properties in `array` that match this string will be returned. This also
+ * applies to nested object properties.
+ * The predicate can be negated by prefixing the string with `!`.
+ *
+ * - `Object`: A pattern object can be used to filter specific properties on objects contained
+ * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ * which have property `name` containing "M" and property `phone` containing "1". A special
+ * property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
+ * against any property of the object or its nested object properties. That's equivalent to the
+ * simple substring match with a `string` as described above. The special property name can be
+ * overwritten, using the `anyPropertyKey` parameter.
+ * The predicate can be negated by prefixing the string with `!`.
+ * For example `{name: "!M"}` predicate will return an array of items which have property `name`
+ * not containing "M".
+ *
+ * Note that a named property will match properties on the same level only, while the special
+ * `$` property will match properties on the same level or deeper. E.g. an array item like
+ * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
+ * **will** be matched by `{$: 'John'}`.
+ *
+ * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
+ * The function is called for each element of the array, with the element, its index, and
+ * the entire array itself as arguments.
+ *
+ * The final result is an array of those elements that the predicate returned true for.
+ *
+ * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
+ * determining if the expected value (from the filter expression) and actual value (from
+ * the object in the array) should be considered a match.
+ *
+ * Can be one of:
+ *
+ * - `function(actual, expected)`:
+ * The function will be given the object value and the predicate value to compare and
+ * should return true if both values should be considered equal.
+ *
+ * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
+ * This is essentially strict comparison of expected and actual.
+ *
+ * - `false|undefined`: A short hand for a function which will look for a substring match in case
+ * insensitive way.
+ *
+ * Primitive values are converted to strings. Objects are not compared against primitives,
+ * unless they have a custom `toString` method (e.g. `Date` objects).
+ *
+ * @param {string=} anyPropertyKey The special property name that matches against any property.
+ * By default `$`.

+ * @ngdoc filter
+ * @name date
+ * @kind function
+ *
+ * @description
+ * Formats `date` to a string based on the requested `format`.
+ *
+ * `format` string can be composed of the following elements:
+ *
+ * * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
+ * * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
+ * * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
+ * * `'MMMM'`: Month in year (January-December)
+ * * `'MMM'`: Month in year (Jan-Dec)
+ * * `'MM'`: Month in year, padded (01-12)
+ * * `'M'`: Month in year (1-12)
+ * * `'LLLL'`: Stand-alone month in year (January-December)
+ * * `'dd'`: Day in month, padded (01-31)
+ * * `'d'`: Day in month (1-31)
+ * * `'EEEE'`: Day in Week,(Sunday-Saturday)
+ * * `'EEE'`: Day in Week, (Sun-Sat)
+ * * `'HH'`: Hour in day, padded (00-23)
+ * * `'H'`: Hour in day (0-23)
+ * * `'hh'`: Hour in AM/PM, padded (01-12)
+ * * `'h'`: Hour in AM/PM, (1-12)
+ * * `'mm'`: Minute in hour, padded (00-59)
+ * * `'m'`: Minute in hour (0-59)
+ * * `'ss'`: Second in minute, padded (00-59)
+ * * `'s'`: Second in minute (0-59)
+ * * `'sss'`: Millisecond in second, padded (000-999)
+ * * `'a'`: AM/PM marker
+ * * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
+ * * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
+ * * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
+ * * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
+ * * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
+ *
+ * `format` string can also be one of the following predefined
+ * {@link guide/i18n localizable formats}:
+ *
+ * * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
+ * (e.g. Sep 3, 2010 12:05:08 PM)
+ * * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM)
+ * * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US locale
+ * (e.g. Friday, September 3, 2010)
+ * * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010)
+ * * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)

+ * * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
+ *
+ * `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
+ * `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
+ * (e.g. `"h 'o''clock'"`).
+ *
+ * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
+ * number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
+ * shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
+ * specified in the string input, the time is considered to be in the local timezone.
+ * @param {string=} format Formatting rules (see Description). If not specified,
+ * `mediumDate` is used.
+ * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
+ * continental US time zone abbreviations, but for general use, use a time zone offset, for
+ * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
+ * If not specified, the timezone of the browser will be used.
+ * @returns {string} Formatted string or the input if input is not recognized as date/millis.

+ * @ngdoc filter
+ * @name orderBy
+ * @kind function
+ *
+ * @description
+ * Returns an array containing the items from the specified `collection`, ordered by a `comparator`
+ * function based on the values computed using the `expression` predicate.
+ *
+ * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
+ * `[{id: 'bar'}, {id: 'foo'}]`.
+ *
+ * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
+ * String, etc).
+ *
+ * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
+ * for the preceeding one. The `expression` is evaluated against each item and the output is used
+ * for comparing with other items.
+ *
+ * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
+ * ascending order.
+ *
+ * The comparison is done using the `comparator` function. If none is specified, a default, built-in
+ * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
+ * strings alphabetically).
+ *
+ * ### Under the hood
+ *
+ * Ordering the specified `collection` happens in two phases:
+ *
+ * 1. All items are passed through the predicate (or predicates), and the returned values are saved
+ * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
+ * through a predicate that extracts the value of the `label` property, would be transformed to:
+ * ```
+ * {
+ * value: 'foo',
+ * type: 'string',
+ * index: ...
+ * }
+ * ```
+ * 2. The comparator function is used to sort the items, based on the derived values, types and
+ * indices.
+ *
+ * If you use a custom comparator, it will be called with pairs of objects of the form
+ * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
+ * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
+ * second, or `1` otherwise.
+ *
+ * In order to ensure that the sorting will be deterministic across platforms, if none of the
+ * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
+ * dummy predicate that returns the item's index as `value`.
+ * (If you are using a custom comparator, make sure it can handle this predicate as well.)
+ *
+ * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
+ * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
+ * it to the comparator. The following rules govern the conversion:
+ *
+ * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
+ * used instead.<br />
+ * (If the object has a `valueOf()` method that returns another object, then the returned object
+ * will be used in subsequent steps.)
+ * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
+ * returns a primitive, its return value will be used instead.<br />
+ * (If the object has a `toString()` method that returns another object, then the returned object
+ * will be used in subsequent steps.)
+ * 3. No conversion; the object itself is used.
+ *
+ * ### The default comparator
+ *
+ * The default, built-in comparator should be sufficient for most usecases. In short, it compares
+ * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
+ * using their index in the original collection, and sorts values of different types by type.
+ *
+ * More specifically, it follows these steps to determine the relative order of items:
+ *
+ * 1. If the compared values are of different types, compare the types themselves alphabetically.
+ * 2. If both values are of type `string`, compare them alphabetically in a case- and
+ * locale-insensitive way.
+ * 3. If both values are objects, compare their indices instead.
+ * 4. Otherwise, return:
+ * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
+ * - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
+ * - `1`, otherwise.
+ *
+ * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
+ * saved as numbers and not strings.
+ *
+ * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
+ * @param {(Function|string|Array.<Function|string>)=} expression - A predicate (or list of
+ * predicates) to be used by the comparator to determine the order of elements.
+ *
+ * Can be one of:
+ *
+ * - `Function`: A getter function. This function will be called with each item as argument and
+ * the return value will be used for sorting.
+ * - `string`: An Angular expression. This expression will be evaluated against each item and the
+ * result will be used for sorting. For example, use `'label'` to sort by a property called
+ * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
+ * property.<br />
+ * (The result of a constant expression is interpreted as a property name to be used for
+ * comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
+ * property called `special name`.)<br />
+ * An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
+ * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
+ * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
+ * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
+ * relative order of two items, the next predicate is used as a tie-breaker.
+ *
+ * **Note:** If the predicate is missing or empty then it defaults to `'+'`.
+ *
+ * @param {boolean=} reverse - If `true`, reverse the sorting order.
+ * @param {(Function)=} comparator - The comparator function used to determine the relative order of
+ * value pairs. If omitted, the built-in comparator will be used.
+ *
+ * @returns {Array} - The sorted array.
+ *
+ *
+ * @example
+ * ### Ordering a table with `ngRepeat`
+ *
+ * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
+ * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
+ * it defaults to the built-in comparator.

+ *
+ * # Alias: {@link ng.directive:ngForm `ngForm`}
+ *
+ * In Angular, forms can be nested. This means that the outer form is valid when all of the child
+ * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
+ * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
+ * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
+ * of controls needs to be determined.
+ *
+ * # CSS classes
+ * - `ng-valid` is set if the form is valid.
+ * - `ng-invalid` is set if the form is invalid.
+ * - `ng-pending` is set if the form is pending.
+ * - `ng-pristine` is set if the form is pristine.
+ * - `ng-dirty` is set if the form is dirty.
+ * - `ng-submitted` is set if the form was submitted.
+ *
+ * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+ *
+ *
+ * # Submitting a form and preventing the default action
+ *
+ * Since the role of forms in client-side Angular applications is different than in classical
+ * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
+ * page reload that sends the data to the server. Instead some javascript logic should be triggered
+ * to handle the form submission in an application-specific way.
+ *
+ * For this reason, Angular prevents the default action (form submission to the server) unless the
+ * `<form>` element has an `action` attribute specified.
+ *
+ * You can use one of the following two ways to specify what javascript method should be called when
+ * a form is submitted:
+ *
+ * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
+ * - {@link ng.directive:ngClick ngClick} directive on the first
+ * button or input field of type submit (input[type=submit])
+ *
+ * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
+ * or {@link ng.directive:ngClick ngClick} directives.
+ * This is because of the following form submission rules in the HTML specification:
+ *
+ * - If a form has only one input field then hitting enter in this field triggers form submit
+ * (`ngSubmit`)
+ * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
+ * doesn't trigger submit
+ * - if a form has one or more input fields and one or more buttons or input[type=submit] then
+ * hitting enter in any of the input fields will trigger the click handler on the *first* button or
+ * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
+ *
+ * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
+ * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
+ * to have access to the updated model.
+ *
+ * ## Animation Hooks
+ *
+ * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
+ * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
+ * other validations that are performed within the form. Animations in ngForm are similar to how
+ * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
+ * as JS animations.
+ *
+ * The following example shows a simple way to utilize CSS transitions to style a form element
+ * that has been rendered as invalid after it has been validated:
+ *
+ * <pre>
+ * //be sure to include ngAnimate as a module to hook into more
+ * //advanced animations
+ * .my-form {
+ * transition:0.5s linear all;
+ * background: white;
+ * }
+ * .my-form.ng-invalid {
+ * background: red;
+ * color:white;
+ * }
+ * </pre>
+ *
+ * @example
+ <example deps="angular-animate.js" animations="true" fixBase="true" module="formExample">
+ <file name="index.html">
+ <script>
+ angular.module('formExample', [])
+ .controller('FormController', ['$scope', function($scope) {
+ $scope.userType = 'guest';
+ }]);
+ </script>
+ <style>
+ .my-form {
+ transition:all linear 0.5s;
+ background: transparent;
+ }
+ .my-form.ng-invalid {
+ background: red;
+ }
+ </style>
+ <form name="myForm" ng-controller="FormController" class="my-form">
+ userType: <input name="input" ng-model="userType" required>
+ <span class="error" ng-show="myForm.input.$error.required">Required!</span><br>
+ <code>userType = {{userType}}</code><br>
+ <code>myForm.input.$valid = {{myForm.input.$valid}}</code><br>
+ <code>myForm.input.$error = {{myForm.input.$error}}</code><br>
+ <code>myForm.$valid = {{myForm.$valid}}</code><br>
+ <code>myForm.$error.required = {{!!myForm.$error.required}}</code><br>
+ </form>
+ </file>
+ <file name="protractor.js" type="protractor">

+ *
+ * @param {string} ngModel Assignable angular expression to data-bind to.
+ * @param {string=} name Property name of the form under which the control is published.
+ * @param {string=} required Adds `required` validation error key if the value is not entered.
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+ * the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+ * `required` when you want to data-bind to the `required` attribute.
+ * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
+ * minlength.
+ * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
+ * maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
+ * any length.
+ * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
+ * that contains the regular expression body that will be converted to a regular expression
+ * as in the ngPattern directive.
+ * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
+ * does not match a RegExp found by evaluating the Angular expression given in the attribute value.
+ * If the expression evaluates to a RegExp object, then this is used directly.
+ * If the expression evaluates to a string, then it will be converted to a RegExp
+ * after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
+ * `new RegExp('^abc$')`.<br />
+ * **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
+ * start at the index of the last search's match, thus not taking the whole input value into
+ * account.
+ * @param {string=} ngChange Angular expression to be executed when input changes due to user
+ * interaction with the input element.
+ * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.

+ *
+ * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like

+ *
+ * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
+ * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
+ * element attribute, it makes the bindings invisible to the user while the page is loading.

+/**
+ * @ngdoc directive
+ * @name ngClass
+ * @restrict AC
+ *
+ * @description
+ * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
+ * an expression that represents all classes to be added.
+ *
+ * The directive operates in three different ways, depending on which of three types the expression
+ * evaluates to:
+ *
+ * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
+ * names.
+ *
+ * 2. If the expression evaluates to an object, then for each key-value pair of the
+ * object with a truthy value the corresponding key is used as a class name.
+ *
+ * 3. If the expression evaluates to an array, each element of the array should either be a string as in
+ * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
+ * to give you more control over what CSS classes appear. See the code below for an example of this.
+ *
+ *
+ * The directive won't add duplicate classes if a particular class was already set.
+ *
+ * When the expression changes, the previously added classes are removed and only then are the
+ * new classes added.
+ *
+ * @knownIssue
+ * You should not use {@link guide/interpolation interpolation} in the value of the `class`
+ * attribute, when using the `ngClass` directive on the same element.
+ * See {@link guide/interpolation#known-issues here} for more info.
+ *
+ * @animations
+ * | Animation | Occurs |
+ * |----------------------------------|-------------------------------------|
+ * | {@link ng.$animate#addClass addClass} | just before the class is applied to the element |
+ * | {@link ng.$animate#removeClass removeClass} | just before the class is removed from the element |
+ *
+ * @element ANY
+ * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
+ * of the evaluation can be a string representing space delimited class
+ * names, an array, or a map of class names to boolean values. In the case of a map, the
+ * names of the properties whose values are truthy will be added as css classes to the
+ * element.
+ *

+ expect(element(by.css('.base-class')).getAttribute('class')).not.
+ toMatch(/my-class/);
+
+ element(by.id('setbtn')).click();
+
+ expect(element(by.css('.base-class')).getAttribute('class')).
+ toMatch(/my-class/);

+ element(by.id('clearbtn')).click();
+
+ expect(element(by.css('.base-class')).getAttribute('class')).not.

+ </file>
+ </example>
+
+
+ ## ngClass and pre-existing CSS3 Transitions/Animations
+ The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
+ Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder

+ * @description
+ * The `ngCloak` directive is used to prevent the Angular html template from being briefly
+ * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
+ * directive to avoid the undesirable flicker effect caused by the html template display.
+ *
+ * The directive can be applied to the `<body>` element, but the preferred usage is to apply
+ * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
+ * of the browser view.
+ *
+ * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
+ * `angular.min.js`.
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * ```css
+ * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
+ * display: none !important;
+ * }
+ * ```
+ *
+ * When this css rule is loaded by the browser, all html elements (including their children) that
+ * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
+ * during the compilation of the template it deletes the `ngCloak` element attribute, making
+ * the compiled element visible.
+ *
+ * For the best result, the `angular.js` script must be loaded in the head section of the html
+ * document; alternatively, the css rule above must be included in the external stylesheet of the
+ * application.

+/**
+ * @ngdoc directive
+ * @name ngController
+ *
+ * @description
+ * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
+ * supports the principles behind the Model-View-Controller design pattern.
+ *
+ * MVC components in angular:
+ *
+ * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
+ * are accessed through bindings.
+ * * View — The template (HTML with data bindings) that is rendered into the View.
+ * * Controller — The `ngController` directive specifies a Controller class; the class contains business
+ * logic behind the application to decorate the scope with functions and values
+ *
+ * Note that you can also attach controllers to the DOM by declaring it in a route definition
+ * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
+ * again using `ng-controller` in the template itself. This will cause the controller to be attached
+ * and executed twice.
+ *
+ * @element ANY
+ * @scope
+ * @priority 500
+ * @param {expression} ngController Name of a constructor function registered with the current
+ * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
+ * that on the current scope evaluates to a constructor function.
+ *
+ * The controller instance can be published into a scope property by specifying
+ * `ng-controller="as propertyName"`.
+ *
+ * If the current `$controllerProvider` is configured to use globals (via
+ * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
+ * also be the name of a globally accessible constructor function (not recommended).
+ *
+ * @example
+ * Here is a simple form for editing user contact information. Adding, removing, clearing, and
+ * greeting are methods declared on the controller (see source tab). These methods can
+ * easily be called from the angular markup. Any changes to the data are automatically reflected
+ * in the View without the need for a manual update.
+ *
+ * Two different declaration styles are included below:
+ *
+ * * one binds methods and properties directly onto the controller using `this`:
+ * `ng-controller="SettingsController1 as settings"`
+ * * one injects `$scope` into the controller:
+ * `ng-controller="SettingsController2"`
+ *
+ * The second option is more common in the Angular community, and is generally used in boilerplates
+ * and in this guide. However, there are advantages to binding properties directly to the controller
+ * and avoiding scope.
+ *
+ * * Using `controller as` makes it obvious which controller you are accessing in the template when
+ * multiple controllers apply to an element.
+ * * If you are writing your controllers as classes you have easier access to the properties and
+ * methods, which will appear on the scope, from inside the controller code.
+ * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
+ * inheritance masking primitives.
+ *
+ * This example demonstrates the `controller as` syntax.
+ *
+ * <example name="ngControllerAs" module="controllerAsExample">
+ * <file name="index.html">

+/**
+ * @ngdoc directive
+ * @name ngCsp
+ *
+ * @element html
+ * @description
+ *
+ * Angular has some features that can break certain
+ * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.
+ *
+ * If you intend to implement these rules then you must tell Angular not to use these features.
+ *
+ * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
+ *
+ *
+ * The following rules affect Angular:
+ *
+ * * `unsafe-eval`: this rule forbids apps to use `eval` or `Function(string)` generated functions
+ * (among other things). Angular makes use of this in the {@link $parse} service to provide a 30%
+ * increase in the speed of evaluating Angular expressions.
+ *
+ * * `unsafe-inline`: this rule forbids apps from inject custom styles into the document. Angular
+ * makes use of this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}).
+ * To make these directives work when a CSP rule is blocking inline styles, you must link to the
+ * `angular-csp.css` in your HTML manually.
+ *
+ * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking unsafe-eval
+ * and automatically deactivates this feature in the {@link $parse} service. This autodetection,
+ * however, triggers a CSP error to be logged in the console:
+ *
+ * ```
+ * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
+ * script in the following Content Security Policy directive: "default-src 'self'". Note that
+ * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
+ * ```
+ *
+ * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
+ * directive on an element of the HTML document that appears before the `<script>` tag that loads
+ * the `angular.js` file.
+ *
+ * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
+ *
+ * You can specify which of the CSP related Angular features should be deactivated by providing
+ * a value for the `ng-csp` attribute. The options are as follows:
+ *
+ * * no-inline-style: this stops Angular from injecting CSS styles into the DOM
+ *
+ * * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings
+ *
+ * You can use these values in the following combinations:
+ *
+ *
+ * * No declaration means that Angular will assume that you can do inline styles, but it will do
+ * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous versions
+ * of Angular.
+ *
+ * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline
+ * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous versions
+ * of Angular.
+ *
+ * * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can inject
+ * inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
+ *
+ * * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can
+ * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
+ *
+ * * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject
+ * styles nor use eval, which is the same as an empty: ng-csp.
+ * E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
+ *
+ * @example
+ * This example shows how to apply the `ngCsp` directive to the `html` tag.
+ ```html
+ <!doctype html>
+ <html ng-app ng-csp>
+ ...
+ ...
+ </html>
+ ```

+/**
+ * @ngdoc directive
+ * @name ngIf
+ * @restrict A
+ * @multiElement
+ *
+ * @description
+ * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
+ * {expression}. If the expression assigned to `ngIf` evaluates to a false
+ * value then the element is removed from the DOM, otherwise a clone of the
+ * element is reinserted into the DOM.
+ *
+ * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
+ * element in the DOM rather than changing its visibility via the `display` css property. A common
+ * case when this difference is significant is when using css selectors that rely on an element's
+ * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
+ *
+ * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
+ * is created when the element is restored. The scope created within `ngIf` inherits from
+ * its parent scope using
+ * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
+ * An important implication of this is if `ngModel` is used within `ngIf` to bind to
+ * a javascript primitive defined in the parent scope. In this case any modifications made to the
+ * variable within the child scope will override (hide) the value in the parent scope.
+ *
+ * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
+ * is if an element's class attribute is directly modified after it's compiled, using something like
+ * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
+ * the added class will be lost because the original compiled state is used to regenerate the element.
+ *
+ * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
+ * and `leave` effects.
+ *
+ * @animations
+ * | Animation | Occurs |
+ * |----------------------------------|-------------------------------------|
+ * | {@link ng.$animate#enter enter} | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |
+ * | {@link ng.$animate#leave leave} | just before the `ngIf` contents are removed from the DOM |
+ *
+ * @element ANY
+ * @scope
+ * @priority 600
+ * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
+ * the element is removed from the DOM tree. If it is truthy a copy of the compiled

+ * server side scripting. Besides these few cases, you should use {@link guide/controller controllers}
+ * rather than `ngInit` to initialize values on a scope.
+ * </div>
+ *
+ * <div class="alert alert-warning">
+ * **Note**: If you have assignment in `ngInit` along with a {@link ng.$filter `filter`}, make

+/**
+ * @ngdoc directive
+ * @name ngList
+ *
+ * @description
+ * Text input that converts between a delimited string and an array of strings. The default
+ * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
+ * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
+ *
+ * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
+ * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
+ * list item is respected. This implies that the user of the directive is responsible for
+ * dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
+ * tab or newline character.
+ * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
+ * when joining the list items back together) and whitespace around each list item is stripped
+ * before it is added to the model.

+ *
+ * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
+ * The controller contains services for data-binding, validation, CSS updates, and value formatting
+ * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
+ * listening to DOM events.
+ * Such DOM related logic should be provided by other directives which make use of
+ * `NgModelController` for data-binding to control elements.
+ * Angular provides this DOM logic for most {@link input `input`} elements.
+ * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
+ * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
+ *
+ * @example
+ * ### Custom Control Example
+ * This example shows how to use `NgModelController` with a custom control to achieve
+ * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+ * collaborate together to achieve the desired result.
+ *
+ * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
+ * contents be edited in place by the user.
+ *
+ * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
+ * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
+ * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
+ * that content using the `$sce` service.
+ *
+ * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
+ <file name="style.css">
+ [contenteditable] {
+ border: 1px solid black;
+ background-color: white;
+ min-height: 20px;
+ }

+ .ng-invalid {
+ border: 1px solid red;

+ link: function(scope, element, attrs, ngModel) {
+ if (!ngModel) return; // do nothing if no ng-model
+
+ // Specify how UI should be updated
+ ngModel.$render = function() {

+ element.on('blur keyup change', function() {
+ scope.$evalAsync(read);
+ });

+ *
+ * This method should be called when a control wants to change the view value; typically,
+ * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
+ * directive calls it when the value of the input changes and {@link ng.directive:select select}
+ * calls it when an option is selected.
+ *
+ * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
+ * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
+ * value sent directly for processing, finally to be applied to `$modelValue` and then the
+ * **expression** specified in the `ng-model` attribute. Lastly, all the registered change listeners,
+ * in the `$viewChangeListeners` list, are called.
+ *
+ * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
+ * and the `default` trigger is not listed, all those actions will remain pending until one of the
+ * `updateOn` events is triggered on the DOM element.
+ * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
+ * directive is used with a custom debounce for this particular event.
+ * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
+ * is specified, once the timer runs out.
+ *
+ * When used with standard inputs, the view value will always be a string (which is in some cases
+ * parsed into another type, such as a `Date` object for `input[date]`.)
+ * However, custom controls might also pass objects to this method. In this case, we should make
+ * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
+ * perform a deep watch of objects, it only looks for a change of identity. If you only change
+ * the property of the object then ngModel will not realize that the object has changed and
+ * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
+ * not change properties of the copy once it has been passed to `$setViewValue`.
+ * Otherwise you may cause the model value on the scope to change incorrectly.
+ *
+ * <div class="alert alert-info">
+ * In any case, the value passed to the method should always reflect the current value
+ * of the control. For example, if you are calling `$setViewValue` for an input element,
+ * you should pass the input DOM value. Otherwise, the control and the scope model become
+ * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
+ * the control's DOM value in any way. If we want to change the control's DOM value
+ * programmatically, we should update the `ngModel` scope expression. Its new value will be
+ * picked up by the model controller, which will run it through the `$formatters`, `$render` it

+ * @ngdoc directive
+ * @name ngModel
+ *
+ * @element input
+ * @priority 1
+ *
+ * @description
+ * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
+ * property on the scope using {@link ngModel.NgModelController NgModelController},
+ * which is created and exposed by this directive.
+ *
+ * `ngModel` is responsible for:
+ *
+ * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
+ * require.
+ * - Providing validation behavior (i.e. required, number, email, url).
+ * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
+ * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
+ * `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
+ * - Registering the control with its parent {@link ng.directive:form form}.
+ *
+ * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
+ * current scope. If the property doesn't already exist on this scope, it will be created
+ * implicitly and added to the scope.
+ *
+ * For best practices on using `ngModel`, see:
+ *
+ * - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
+ *
+ * For basic examples, how to use `ngModel`, see:
+ *
+ * - {@link ng.directive:input input}
+ * - {@link input[text] text}
+ * - {@link input[checkbox] checkbox}
+ * - {@link input[radio] radio}
+ * - {@link input[number] number}
+ * - {@link input[email] email}
+ * - {@link input[url] url}
+ * - {@link input[date] date}
+ * - {@link input[datetime-local] datetime-local}
+ * - {@link input[time] time}
+ * - {@link input[month] month}
+ * - {@link input[week] week}
+ * - {@link ng.directive:select select}
+ * - {@link ng.directive:textarea textarea}
+ *
+ * # Complex Models (objects or collections)
+ *
+ * By default, `ngModel` watches the model by reference, not value. This is important to know when
+ * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
+ * object or collection change, `ngModel` will not be notified and so the input will not be re-rendered.
+ *
+ * The model must be assigned an entirely new object or collection before a re-rendering will occur.
+ *
+ * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
+ * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
+ * if the select is given the `multiple` attribute.
+ *
+ * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
+ * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
+ * not trigger a re-rendering of the model.
+ *
+ * # CSS classes
+ * The following CSS classes are added and removed on the associated input/select/textarea element
+ * depending on the validity of the model.
+ *
+ * - `ng-valid`: the model is valid
+ * - `ng-invalid`: the model is invalid
+ * - `ng-valid-[key]`: for each valid key added by `$setValidity`
+ * - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
+ * - `ng-pristine`: the control hasn't been interacted with yet
+ * - `ng-dirty`: the control has been interacted with
+ * - `ng-touched`: the control has been blurred
+ * - `ng-untouched`: the control hasn't been blurred
+ * - `ng-pending`: any `$asyncValidators` are unfulfilled
+ * - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
+ * by the {@link ngModel.NgModelController#$isEmpty} method
+ * - `ng-not-empty`: the view contains a non-empty value
+ *
+ * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+ *
+ * ## Animation Hooks
+ *
+ * Animations within models are triggered when any of the associated CSS classes are added and removed
+ * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
+ * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
+ * The animations that are triggered within ngModel are similar to how they work in ngClass and
+ * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
+ *
+ * The following example shows a simple way to utilize CSS transitions to style an input element
+ * that has been rendered as invalid after it has been validated:
+ *
+ * <pre>
+ * //be sure to include ngAnimate as a module to hook into more
+ * //advanced animations
+ * .my-input {
+ * transition:0.5s linear all;
+ * background: white;
+ * }
+ * .my-input.ng-invalid {
+ * background: red;
+ * color:white;
+ * }
+ * </pre>
+ *
+ * @example
+ * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample">
+ <file name="index.html">
+ <script>
+ angular.module('inputExample', [])
+ .controller('ExampleController', ['$scope', function($scope) {
+ $scope.val = '1';
+ }]);
+ </script>
+ <style>
+ .my-input {
+ transition:all linear 0.5s;
+ background: transparent;
+ }
+ .my-input.ng-invalid {
+ color:white;
+ background: red;
+ }
+ </style>
+ <p id="inputDescription">
+ Update input to see transitions when valid/invalid.
+ Integer is a valid value.
+ </p>
+ <form name="testForm" ng-controller="ExampleController">
+ <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input"
+ aria-describedby="inputDescription" />
+ </form>
+ </file>
+ * </example>
+ *
+ * ## Binding to a getter/setter
+ *
+ * Sometimes it's helpful to bind `ngModel` to a getter/setter function. A getter/setter is a
+ * function that returns a representation of the model when called with zero arguments, and sets
+ * the internal state of a model when called with an argument. It's sometimes useful to use this
+ * for models that have an internal representation that's different from what the model exposes
+ * to the view.
+ *
+ * <div class="alert alert-success">
+ * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
+ * frequently than other parts of your code.
+ * </div>
+ *
+ * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
+ * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
+ * a `<form>`, which will enable this behavior for all `<input>`s within it. See
+ * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
+ *
+ * The following example shows how to use `ngModel` with a getter/setter:
+ *
+ * @example
+ * <example name="ngModel-getter-setter" module="getterSetterExample">
+ <file name="index.html">
+ <div ng-controller="ExampleController">
+ <form name="userForm">
+ <label>Name:
+ <input type="text" name="userName"
+ ng-model="user.name"
+ ng-model-options="{ getterSetter: true }" />
+ </label>
+ </form>
+ <pre>user.name = <span ng-bind="user.name()"></span></pre>
+ </div>
+ </file>
+ <file name="app.js">
+ angular.module('getterSetterExample', [])
+ .controller('ExampleController', ['$scope', function($scope) {
+ var _name = 'Brian';
+ $scope.user = {
+ name: function(newName) {
+ // Note that newName can be undefined for two reasons:
+ // 1. Because it is called as a getter and thus called with no arguments
+ // 2. Because the property should actually be set to undefined. This happens e.g. if the
+ // input is invalid
+ return arguments.length ? (_name = newName) : _name;
+ }

+ * @description
+ * Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of
+ * events that will trigger a model update and/or a debouncing delay so that the actual update only
+ * takes place when a timer expires; this timer will be reset after another change takes place.
+ *
+ * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
+ * be different from the value in the actual model. This means that if you update the model you
+ * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in
+ * order to make sure it is synchronized with the model and that any debounced action is canceled.
+ *
+ * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`}
+ * method is by making sure the input is placed inside a form that has a `name` attribute. This is
+ * important because `form` controllers are published to the related scope under the name in their
+ * `name` attribute.
+ *
+ * Any pending changes will take place immediately when an enclosing form is submitted via the
+ * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
+ * to have access to the updated model.
+ *
+ * `ngModelOptions` has an effect on the element it's declared on and its descendants.

+ * - `updateOn`: string specifying which event should the input be bound to. You can set several
+ * events using an space delimited list. There is a special event called `default` that
+ * matches the default events belonging of the control.
+ * - `debounce`: integer value which contains the debounce model update value in milliseconds. A
+ * value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
+ * custom value for each event. For example:
+ * `ng-model-options="{ updateOn: 'default blur', debounce: { 'default': 500, 'blur': 0 } }"`
+ * - `allowInvalid`: boolean value which indicates that the model can be set with values that did
+ * not validate correctly instead of the default behavior of setting the model to undefined.
+ * - `getterSetter`: boolean value which determines whether or not to treat functions bound to
+ `ngModel` as getters/setters.
+ * - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
+ * `<input type="date">`, `<input type="time">`, ... . It understands UTC/GMT and the
+ * continental US time zone abbreviations, but for general use, use a time zone offset, for
+ * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
+ * If not specified, the timezone of the browser will be used.
+ *
+ * @example
+
+ The following example shows how to override immediate updates. Changes on the inputs within the
+ form will update the model only when the control loses focus (blur event). If `escape` key is
+ pressed while the input field is focused, the value is reset to the value in the current model.

+/**
+ * @ngdoc directive
+ * @name ngOptions
+ * @restrict A
+ *
+ * @description
+ *
+ * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
+ * elements for the `<select>` element using the array or object obtained by evaluating the
+ * `ngOptions` comprehension expression.
+ *
+ * In many cases, `ngRepeat` can be used on `<option>` elements instead of `ngOptions` to achieve a
+ * similar result. However, `ngOptions` provides some benefits such as reducing memory and
+ * increasing speed by not creating a new scope for each repeated instance, as well as providing
+ * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
+ * comprehension expression. `ngOptions` should be used when the `<select>` model needs to be bound
+ * to a non-string value. This is because an option element can only be bound to string values at
+ * present.
+ *
+ * When an item in the `<select>` menu is selected, the array element or object property
+ * represented by the selected option will be bound to the model identified by the `ngModel`
+ * directive.
+ *
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
+ * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
+ * option. See example below for demonstration.
+ *
+ * ## Complex Models (objects or collections)
+ *
+ * By default, `ngModel` watches the model by reference, not value. This is important to know when
+ * binding the select to a model that is an object or a collection.
+ *
+ * One issue occurs if you want to preselect an option. For example, if you set
+ * the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection,
+ * because the objects are not identical. So by default, you should always reference the item in your collection
+ * for preselections, e.g.: `$scope.selected = $scope.collection[3]`.
+ *
+ * Another solution is to use a `track by` clause, because then `ngOptions` will track the identity
+ * of the item not by reference, but by the result of the `track by` expression. For example, if your
+ * collection items have an id property, you would `track by item.id`.
+ *
+ * A different issue with objects or collections is that ngModel won't detect if an object property or
+ * a collection item changes. For that reason, `ngOptions` additionally watches the model using
+ * `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute.
+ * This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection
+ * has not changed identity, but only a property on the object or an item in the collection changes.
+ *
+ * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection
+ * if the model is an array). This means that changing a property deeper than the first level inside the
+ * object/collection will not trigger a re-rendering.
+ *
+ * ## `select` **`as`**
+ *
+ * Using `select` **`as`** will bind the result of the `select` expression to the model, but
+ * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
+ * or property name (for object data sources) of the value within the collection. If a **`track by`** expression
+ * is used, the result of that expression will be set as the value of the `option` and `select` elements.
+ *
+ *
+ * ### `select` **`as`** and **`track by`**
+ *
+ * <div class="alert alert-warning">
+ * Be careful when using `select` **`as`** and **`track by`** in the same expression.
+ * </div>
+ *
+ * Given this array of items on the $scope:
+ *
+ * ```js
+ * $scope.items = [{
+ * id: 1,
+ * label: 'aLabel',
+ * subItem: { name: 'aSubItem' }
+ * }, {
+ * id: 2,
+ * label: 'bLabel',
+ * subItem: { name: 'bSubItem' }
+ * }];
+ * ```
+ *
+ * This will work:
+ *
+ * ```html
+ * <select ng-options="item as item.label for item in items track by item.id" ng-model="selected"></select>
+ * ```
+ * ```js
+ * $scope.selected = $scope.items[0];
+ * ```
+ *
+ * but this will not work:
+ *
+ * ```html
+ * <select ng-options="item.subItem as item.label for item in items track by item.id" ng-model="selected"></select>
+ * ```
+ * ```js
+ * $scope.selected = $scope.items[0].subItem;
+ * ```
+ *
+ * In both examples, the **`track by`** expression is applied successfully to each `item` in the
+ * `items` array. Because the selected option has been set programmatically in the controller, the
+ * **`track by`** expression is also applied to the `ngModel` value. In the first example, the
+ * `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with
+ * no issue. In the second example, the `ngModel` value is `items[0].subItem` and the **`track by`**
+ * expression evaluates to `items[0].subItem.id` (which is undefined). As a result, the model value
+ * is not matched against any `<option>` and the `<select>` appears as having no selected value.
+ *
+ *
+ * @param {string} ngModel Assignable angular expression to data-bind to.
+ * @param {string=} name Property name of the form under which the control is published.
+ * @param {string=} required The control is considered valid only if value is entered.
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+ * the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+ * `required` when you want to data-bind to the `required` attribute.
+ * @param {comprehension_expression=} ngOptions in one of the following forms:
+ *
+ * * for array data sources:
+ * * `label` **`for`** `value` **`in`** `array`
+ * * `select` **`as`** `label` **`for`** `value` **`in`** `array`
+ * * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
+ * * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array`
+ * * `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
+ * * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
+ * * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr`
+ * (for including a filter with `track by`)
+ * * for object data sources:
+ * * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ * * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ * * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
+ * * `label` **`disable when`** `disable` **`for (`**`key`**`,`** `value`**`) in`** `object`
+ * * `select` **`as`** `label` **`group by`** `group`
+ * **`for` `(`**`key`**`,`** `value`**`) in`** `object`
+ * * `select` **`as`** `label` **`disable when`** `disable`
+ * **`for` `(`**`key`**`,`** `value`**`) in`** `object`
+ *
+ * Where:
+ *
+ * * `array` / `object`: an expression which evaluates to an array / object to iterate over.
+ * * `value`: local variable which will refer to each item in the `array` or each property value
+ * of `object` during iteration.
+ * * `key`: local variable which will refer to a property name in `object` during iteration.
+ * * `label`: The result of this expression will be the label for `<option>` element. The
+ * `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
+ * * `select`: The result of this expression will be bound to the model of the parent `<select>`
+ * element. If not specified, `select` expression will default to `value`.
+ * * `group`: The result of this expression will be used to group options using the `<optgroup>`
+ * DOM element.
+ * * `disable`: The result of this expression will be used to disable the rendered `<option>`
+ * element. Return `true` to disable.
+ * * `trackexpr`: Used when working with an array of objects. The result of this expression will be
+ * used to identify the objects in the array. The `trackexpr` will most likely refer to the
+ * `value` variable (e.g. `value.propertyName`). With this the selection is preserved
+ * even when the options are recreated (e.g. reloaded from the server).

+/**
+ * @ngdoc directive
+ * @name ngPluralize
+ * @restrict EA
+ *
+ * @description
+ * `ngPluralize` is a directive that displays messages according to en-US localization rules.
+ * These rules are bundled with angular.js, but can be overridden
+ * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
+ * by specifying the mappings between
+ * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
+ * and the strings to be displayed.
+ *
+ * # Plural categories and explicit number rules
+ * There are two
+ * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
+ * in Angular's default en-US locale: "one" and "other".
+ *
+ * While a plural category may match many numbers (for example, in en-US locale, "other" can match
+ * any number that is not 1), an explicit number rule can only match one number. For example, the
+ * explicit number rule for "3" matches the number 3. There are examples of plural categories
+ * and explicit number rules throughout the rest of this documentation.
+ *
+ * # Configuring ngPluralize
+ * You configure ngPluralize by providing 2 attributes: `count` and `when`.
+ * You can also provide an optional attribute, `offset`.
+ *
+ * The value of the `count` attribute can be either a string or an {@link guide/expression
+ * Angular expression}; these are evaluated on the current scope for its bound value.
+ *
+ * The `when` attribute specifies the mappings between plural categories and the actual
+ * string to be displayed. The value of the attribute should be a JSON object.
+ *
+ * The following example shows how to configure ngPluralize:
+ *
+ * ```html
+ * <ng-pluralize count="personCount"
+ when="{'0': 'Nobody is viewing.',
+ * 'one': '1 person is viewing.',
+ * 'other': '{} people are viewing.'}">
+ * </ng-pluralize>
+ *```
+ *
+ * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
+ * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
+ * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
+ * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
+ * show "a dozen people are viewing".
+ *
+ * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
+ * into pluralized strings. In the previous example, Angular will replace `{}` with
+ * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
+ * for <span ng-non-bindable>{{numberExpression}}</span>.
+ *
+ * If no rule is defined for a category, then an empty string is displayed and a warning is generated.
+ * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
+ *
+ * # Configuring ngPluralize with offset
+ * The `offset` attribute allows further customization of pluralized text, which can result in
+ * a better user experience. For example, instead of the message "4 people are viewing this document",
+ * you might display "John, Kate and 2 others are viewing this document".
+ * The offset attribute allows you to offset a number by any desired value.
+ * Let's take a look at an example:
+ *
+ * ```html
+ * <ng-pluralize count="personCount" offset=2
+ * when="{'0': 'Nobody is viewing.',
+ * '1': '{{person1}} is viewing.',
+ * '2': '{{person1}} and {{person2}} are viewing.',
+ * 'one': '{{person1}}, {{person2}} and one other person are viewing.',
+ * 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
+ * </ng-pluralize>
+ * ```
+ *
+ * Notice that we are still using two plural categories(one, other), but we added
+ * three explicit number rules 0, 1 and 2.
+ * When one person, perhaps John, views the document, "John is viewing" will be shown.
+ * When three people view the document, no explicit number rule is found, so
+ * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
+ * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
+ * is shown.
+ *
+ * Note that when you specify offsets, you must provide explicit number rules for
+ * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
+ * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
+ * plural categories "one" and "other".
+ *
+ * @param {string|expression} count The variable to be bound to.
+ * @param {string} when The mapping between plural category to its corresponding strings.
+ * @param {number=} offset Offset to deduct from the total number.
+ *
+ * @example

+/**
+ * @ngdoc directive
+ * @name ngRepeat
+ * @multiElement
+ *
+ * @description
+ * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
+ * instance gets its own scope, where the given loop variable is set to the current collection item,
+ * and `$index` is set to the item index or key.
+ *
+ * Special properties are exposed on the local scope of each template instance, including:
+ *
+ * | Variable | Type | Details |
+ * |-----------|-----------------|-----------------------------------------------------------------------------|
+ * | `$index` | {@type number} | iterator offset of the repeated element (0..length-1) |
+ * | `$first` | {@type boolean} | true if the repeated element is first in the iterator. |
+ * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
+ * | `$last` | {@type boolean} | true if the repeated element is last in the iterator. |
+ * | `$even` | {@type boolean} | true if the iterator position `$index` is even (otherwise false). |
+ * | `$odd` | {@type boolean} | true if the iterator position `$index` is odd (otherwise false). |
+ *
+ * <div class="alert alert-info">
+ * Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
+ * This may be useful when, for instance, nesting ngRepeats.
+ * </div>
+ *
+ *
+ * # Iterating over object properties
+ *
+ * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
+ * syntax:
+ *
+ * ```js
+ * <div ng-repeat="(key, value) in myObj"> ... </div>
+ * ```
+ *
+ * However, there are a limitations compared to array iteration:
+ *
+ * - The JavaScript specification does not define the order of keys
+ * returned for an object, so Angular relies on the order returned by the browser
+ * when running `for key in myObj`. Browsers generally follow the strategy of providing
+ * keys in the order in which they were defined, although there are exceptions when keys are deleted
+ * and reinstated. See the
+ * [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
+ *
+ * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
+ * it's a prefix used by Angular for public (`$`) and private (`$$`) properties.
+ *
+ * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
+ * objects, and will throw an error if used with one.
+ *
+ * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
+ * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
+ * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
+ * or implement a `$watch` on the object yourself.
+ *
+ *
+ * # Tracking and Duplicates
+ *
+ * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
+ * the collection. When a change happens, ngRepeat then makes the corresponding changes to the DOM:
+ *
+ * * When an item is added, a new instance of the template is added to the DOM.
+ * * When an item is removed, its template instance is removed from the DOM.
+ * * When items are reordered, their respective templates are reordered in the DOM.
+ *
+ * To minimize creation of DOM elements, `ngRepeat` uses a function
+ * to "keep track" of all items in the collection and their corresponding DOM elements.
+ * For example, if an item is added to the collection, ngRepeat will know that all other items
+ * already have DOM elements, and will not re-render them.
+ *
+ * The default tracking function (which tracks items by their identity) does not allow
+ * duplicate items in arrays. This is because when there are duplicates, it is not possible
+ * to maintain a one-to-one mapping between collection items and DOM elements.
+ *
+ * If you do need to repeat duplicate items, you can substitute the default tracking behavior
+ * with your own using the `track by` expression.
+ *
+ * For example, you may track items by the index of each item in the collection, using the
+ * special scope property `$index`:
+ * ```html
+ * <div ng-repeat="n in [42, 42, 43, 43] track by $index">
+ * {{n}}
+ * </div>
+ * ```
+ *
+ * You may also use arbitrary expressions in `track by`, including references to custom functions
+ * on the scope:
+ * ```html
+ * <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
+ * {{n}}
+ * </div>
+ * ```
+ *
+ * <div class="alert alert-success">
+ * If you are working with objects that have an identifier property, you should track
+ * by the identifier instead of the whole object. Should you reload your data later, `ngRepeat`
+ * will not have to rebuild the DOM elements for items it has already rendered, even if the
+ * JavaScript objects in the collection have been substituted for new ones. For large collections,
+ * this significantly improves rendering performance. If you don't have a unique identifier,
+ * `track by $index` can also provide a performance boost.
+ * </div>
+ * ```html
+ * <div ng-repeat="model in collection track by model.id">
+ * {{model.name}}
+ * </div>
+ * ```
+ *
+ * When no `track by` expression is provided, it is equivalent to tracking by the built-in
+ * `$id` function, which tracks items by their identity:
+ * ```html
+ * <div ng-repeat="obj in collection track by $id(obj)">
+ * {{obj.prop}}
+ * </div>
+ * ```
+ *
+ * <div class="alert alert-warning">
+ * **Note:** `track by` must always be the last expression:
+ * </div>
+ * ```
+ * <div ng-repeat="model in collection | orderBy: 'id' as filtered_result track by model.id">
+ * {{model.name}}
+ * </div>
+ * ```
+ *
+ * # Special repeat start and end points
+ * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
+ * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
+ * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
+ * up to and including the ending HTML tag where **ng-repeat-end** is placed.
+ *
+ * The example below makes use of this feature:
+ * ```html
+ * <header ng-repeat-start="item in items">
+ * Header {{ item }}
+ * </header>
+ * <div class="body">
+ * Body {{ item }}
+ * </div>
+ * <footer ng-repeat-end>
+ * Footer {{ item }}
+ * </footer>
+ * ```
+ *
+ * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
+ * ```html
+ * <header>
+ * Header A
+ * </header>
+ * <div class="body">
+ * Body A
+ * </div>
+ * <footer>
+ * Footer A
+ * </footer>
+ * <header>
+ * Header B
+ * </header>
+ * <div class="body">
+ * Body B
+ * </div>
+ * <footer>
+ * Footer B
+ * </footer>
+ * ```
+ *
+ * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
+ * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
+ *
+ * @animations
+ * | Animation | Occurs |
+ * |----------------------------------|-------------------------------------|
+ * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter |
+ * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out |
+ * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered |
+ *
+ * See the example below for defining CSS animations with ngRepeat.
+ *
+ * @element ANY
+ * @scope
+ * @priority 1000
+ * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
+ * formats are currently supported:
+ *
+ * * `variable in expression` – where variable is the user defined loop variable and `expression`
+ * is a scope expression giving the collection to enumerate.
+ *
+ * For example: `album in artist.albums`.
+ *
+ * * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
+ * and `expression` is the scope expression giving the collection to enumerate.
+ *
+ * For example: `(name, age) in {'adam':10, 'amalie':12}`.
+ *
+ * * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
+ * which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
+ * is specified, ng-repeat associates elements by identity. It is an error to have
+ * more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
+ * mapped to the same DOM element, which is not possible.)
+ *
+ * Note that the tracking expression must come last, after any filters, and the alias expression.
+ *
+ * For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements
+ * will be associated by item identity in the array.
+ *
+ * For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
+ * `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
+ * with the corresponding item in the array by identity. Moving the same object in array would move the DOM
+ * element in the same way in the DOM.
+ *
+ * For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
+ * case the object identity does not matter. Two objects are considered equivalent as long as their `id`
+ * property is same.
+ *
+ * For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
+ * to items in conjunction with a tracking expression.
+ *
+ * * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
+ * intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
+ * when a filter is active on the repeater, but the filtered result set is empty.
+ *
+ * For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
+ * the items have been processed through the filter.
+ *
+ * Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end
+ * (and not as operator, inside an expression).
+ *
+ * For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` .
+ *
+ * @example
+ * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
+ * results by name. New (entering) and removed (leaving) items are animated.

+/**
+ * @ngdoc directive
+ * @name ngShow
+ * @multiElement
+ *
+ * @description
+ * The `ngShow` directive shows or hides the given HTML element based on the expression
+ * provided to the `ngShow` attribute. The element is shown or hidden by removing or adding
+ * the `.ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
+ * in AngularJS and sets the display style to none (using an !important flag).
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * ```html
+ * <!-- when $scope.myValue is truthy (element is visible) -->
+ * <div ng-show="myValue"></div>
+ *
+ * <!-- when $scope.myValue is falsy (element is hidden) -->
+ * <div ng-show="myValue" class="ng-hide"></div>
+ * ```
+ *
+ * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added to the class
+ * attribute on the element causing it to become hidden. When truthy, the `.ng-hide` CSS class is removed
+ * from the element causing the element not to appear hidden.
+ *
+ * ## Why is !important used?
+ *
+ * You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector
+ * can be easily overridden by heavier selectors. For example, something as simple
+ * as changing the display style on a HTML list item would make hidden elements appear visible.
+ * This also becomes a bigger issue when dealing with CSS frameworks.
+ *
+ * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
+ * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
+ * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
+ *
+ * ### Overriding `.ng-hide`
+ *
+ * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change
+ * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`
+ * class CSS. Note that the selector that needs to be used is actually `.ng-hide:not(.ng-hide-animate)` to cope
+ * with extra animation classes that can be added.
+ *
+ * ```css
+ * .ng-hide:not(.ng-hide-animate) {
+ * /* this is just another form of hiding an element */
+ * display: block!important;
+ * position: absolute;
+ * top: -9999px;
+ * left: -9999px;
+ * }
+ * ```
+ *
+ * By default you don't need to override in CSS anything and the animations will work around the display style.
+ *
+ * ## A note about animations with `ngShow`
+ *
+ * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
+ * is true and false. This system works like the animation system present with ngClass except that
+ * you must also include the !important flag to override the display property
+ * so that you can perform an animation when the element is hidden during the time of the animation.
+ *
+ * ```css
+ * //
+ * //a working example can be found at the bottom of this page
+ * //
+ * .my-element.ng-hide-add, .my-element.ng-hide-remove {
+ * /* this is required as of 1.3x to properly
+ * apply all styling in a show/hide animation */
+ * transition: 0s linear all;
+ * }
+ *
+ * .my-element.ng-hide-add-active,
+ * .my-element.ng-hide-remove-active {
+ * /* the transition is defined in the active class */
+ * transition: 1s linear all;
+ * }
+ *
+ * .my-element.ng-hide-add { ... }
+ * .my-element.ng-hide-add.ng-hide-add-active { ... }
+ * .my-element.ng-hide-remove { ... }
+ * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
+ * ```
+ *
+ * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display
+ * property to block during animation states--ngAnimate will handle the style toggling automatically for you.
+ *

+/**
+ * @ngdoc directive
+ * @name ngHide
+ * @multiElement
+ *
+ * @description
+ * The `ngHide` directive shows or hides the given HTML element based on the expression
+ * provided to the `ngHide` attribute. The element is shown or hidden by removing or adding
+ * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
+ * in AngularJS and sets the display style to none (using an !important flag).
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * ```html
+ * <!-- when $scope.myValue is truthy (element is hidden) -->
+ * <div ng-hide="myValue" class="ng-hide"></div>
+ *
+ * <!-- when $scope.myValue is falsy (element is visible) -->
+ * <div ng-hide="myValue"></div>
+ * ```
+ *
+ * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added to the class
+ * attribute on the element causing it to become hidden. When falsy, the `.ng-hide` CSS class is removed
+ * from the element causing the element not to appear hidden.
+ *
+ * ## Why is !important used?
+ *
+ * You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector
+ * can be easily overridden by heavier selectors. For example, something as simple
+ * as changing the display style on a HTML list item would make hidden elements appear visible.
+ * This also becomes a bigger issue when dealing with CSS frameworks.
+ *
+ * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
+ * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
+ * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
+ *
+ * ### Overriding `.ng-hide`
+ *
+ * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change
+ * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`
+ * class in CSS:
+ *
+ * ```css
+ * .ng-hide {
+ * /* this is just another form of hiding an element */
+ * display: block!important;
+ * position: absolute;
+ * top: -9999px;
+ * left: -9999px;
+ * }
+ * ```
+ *
+ * By default you don't need to override in CSS anything and the animations will work around the display style.
+ *
+ * ## A note about animations with `ngHide`
+ *
+ * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
+ * is true and false. This system works like the animation system present with ngClass, except that the `.ng-hide`
+ * CSS class is added and removed for you instead of your own CSS class.
+ *
+ * ```css
+ * //
+ * //a working example can be found at the bottom of this page
+ * //
+ * .my-element.ng-hide-add, .my-element.ng-hide-remove {
+ * transition: 0.5s linear all;
+ * }
+ *
+ * .my-element.ng-hide-add { ... }
+ * .my-element.ng-hide-add.ng-hide-add-active { ... }
+ * .my-element.ng-hide-remove { ... }
+ * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
+ * ```
+ *
+ * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display
+ * property to block during animation states--ngAnimate will handle the style toggling automatically for you.
+ *

+ *
+ * @description
+ * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
+ * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
+ * as specified in the template.
+ *
+ * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
+ * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
+ * matches the value obtained from the evaluated expression. In other words, you define a container element
+ * (where you place the directive), place an expression on the **`on="..."` attribute**
+ * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
+ * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
+ * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
+ * attribute is displayed.
+ *
+ * <div class="alert alert-info">
+ * Be aware that the attribute values to match against cannot be expressions. They are interpreted
+ * as literal string values to match against.
+ * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
+ * value of the expression `$scope.someVal`.

+ * You can specify that you want to insert a named transclusion slot, instead of the default slot, by providing the slot name
+ * as the value of the `ng-transclude` or `ng-transclude-slot` attribute.
+ *
+ * If the transcluded content is not empty (i.e. contains one or more DOM nodes, including whitespace text nodes), any existing

+ * If the transcluded content is empty, the existing content is left intact. This lets you provide fallback content in the case

+/**
+ * @ngdoc directive
+ * @name select
+ * @restrict E
+ *
+ * @description
+ * HTML `SELECT` element with angular data-binding.
+ *
+ * The `select` directive is used together with {@link ngModel `ngModel`} to provide data-binding
+ * between the scope and the `<select>` control (including setting default values).
+ * It also handles dynamic `<option>` elements, which can be added using the {@link ngRepeat `ngRepeat}` or
+ * {@link ngOptions `ngOptions`} directives.
+ *
+ * When an item in the `<select>` menu is selected, the value of the selected option will be bound
+ * to the model identified by the `ngModel` directive. With static or repeated options, this is
+ * the content of the `value` attribute or the textContent of the `<option>`, if the value attribute is missing.
+ * If you want dynamic value attributes, you can use interpolation inside the value attribute.
+ *
+ * <div class="alert alert-warning">
+ * Note that the value of a `select` directive used without `ngOptions` is always a string.
+ * When the model needs to be bound to a non-string value, you must either explicitly convert it
+ * using a directive (see example below) or use `ngOptions` to specify the set of options.
+ * This is because an option element can only be bound to string values at present.
+ * </div>
+ *
+ * If the viewValue of `ngModel` does not match any of the options, then the control
+ * will automatically add an "unknown" option, which it then removes when the mismatch is resolved.
+ *
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
+ * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
+ * option. See example below for demonstration.
+ *
+ * <div class="alert alert-info">
+ * In many cases, `ngRepeat` can be used on `<option>` elements instead of {@link ng.directive:ngOptions
+ * ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits, such as
+ * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
+ * comprehension expression, and additionally in reducing memory and increasing speed by not creating
+ * a new scope for each repeated instance.
+ * </div>
+ *
+ *
+ * @param {string} ngModel Assignable angular expression to data-bind to.
+ * @param {string=} name Property name of the form under which the control is published.
+ * @param {string=} multiple Allows multiple options to be selected. The selected values will be
+ * bound to the model as an array.
+ * @param {string=} required Sets `required` validation error key if the value is not entered.
+ * @param {string=} ngRequired Adds required attribute and required validation constraint to
+ * the element when the ngRequired expression evaluates to true. Use ngRequired instead of required
+ * when you want to data-bind to the required attribute.
+ * @param {string=} ngChange Angular expression to be executed when selected option(s) changes due to user
+ * interaction with the select element.
+ * @param {string=} ngOptions sets the options that the select is populated with and defines what is
+ * set on the model on selection. See {@link ngOptions `ngOptions`}.
+ *

+ * fusion if the section is applied to an array and iteratees accept only
