| 10 | * BIOS Parser API usage: |

| 12 | * 1) bios_parser::getStrings gets all the attribute names and the preconfigured |
| 13 | * strings used in representing the values of the attributes. This will be |
| 14 | * used to populate the BIOS String table. |
| 15 | * |
| 16 | * 2) bios_enum::setupValueLookup (similar API for other supported BIOS |
| 17 | * attribute types) has to be invoked to setup the lookup data structure for |
| 18 | * all the attributes of that type. This API needs to be invoked before |
| 19 | * invoking bios_enum::getValues and bios_enum::getAttrValue. |
| 20 | * |
| 21 | * 3) bios_enum::getValues is invoked to populate the BIOS attribute table for |
| 22 | * BIOSEnumeration and BIOSEnumerationReadonly types.(similar API for other |
| 23 | * BIOS attribute types) |
| 24 | * |
| 25 | * 4) bios_enum::getAttrValue will return the current values for the BIOS |
| 26 | * enumeration attribute. If there is no D-Bus mapping for the attribute then |
| 27 | * default value is returned.(similar API for other BIOS attribute types). |
