Get OCC Objects
    [Documentation]  Get the OCC objects and return as a list.

    # Example:
    # {
    #     "/org/open_power/control/occ0": {
    #          "OccActive": 0
    # },
    #     "/org/open_power/control/occ1": {
    #          "OccActive": 1
    # }

    ${occ_list}=  Get Endpoint Paths  ${OPENPOWER_CONTROL}  occ*

    [Return]  ${occ_list}


Get OCC Active State
    [Documentation]  Get the OCC "OccActive" and return the attribute value.
    [Arguments]  ${occ_object}

    # Description of argument(s):
    # occ_object   OCC object path.
    #             (e.g. "/org/open_power/control/occ0").

    ${occ_attribute}=  Read Attribute  ${occ_object}  OccActive
    [Return]  ${occ_attribute}


Count Object Entries
    [Documentation]  Count the occurrence number of a given object.
    [Arguments]  ${object_base_uri_path}  ${object_name}

    # Description of argument(s):
    # object_base_uri_path    Object base path
    #                         (e.g. "/org/open_power/control/").
    # object_name             Object name (e.g. "occ", "cpu" etc).

    ${object_list}=  Get Endpoint Paths
    ...  ${object_base_uri_path}  ${object_name}

    [Return]  ${list_count}


Read Object Attribute
    [Documentation]  Return object attribute data.
    [Arguments]  ${object_base_uri_path}  ${attribute_name}

    # Description of argument(s):
    # object_base_uri_path       Object path.
    #                   (e.g. "/org/open_power/control/occ0").
    # attribute_name    Object attribute name.

    [Return]  ${content["data"]}


Verify OCC State
    [Documentation]  Check OCC active state.
    [Arguments]  ${expected_occ_active}=${1}
    # Description of Argument(s):
    # expected_occ_active  The expected occ_active value (i.e. 1/0).

    # Example cpu_list data output:
    #  /xyz/openbmc_project/inventory/system/chassis/motherboard/cpu0
    #  /xyz/openbmc_project/inventory/system/chassis/motherboard/cpu1
    ${cpu_list}=  Get Endpoint Paths
