Handles camelCase/snake_case key name variants for OnePlatform compatibility. Indices and slices in resource_key are ignored -- they are not needed for repeated field queries. Args: resource_key: Ordered list of key names/indices, applied left to right. Each element in the list may be one of: str - A resource property name. This could be a class attribute name or a dict index. int - A list index. Selects one member is the list. Negative indices count from the end of the list, starting with -1 for the last element in the list. An out of bounds index is not an error; it produces the value None. None - A list slice. Selects all members of a list or dict like object. A slice of an empty dict or list is an empty dict or list. message: The known proto message type if not None.

Handles camelCase/snake_case key name variants for OnePlatform compatibility. Indices and slices in resource_key are ignored to normalize the lookup. This means that the lookup can determine the existence of an attribute name, but not a specific value among all repeated values. Args: resource_key: Ordered list of key names/indices, applied left to right. Each element in the list may be one of: str - A resource property name. This could be a class attribute name or a dict index. int - A list index. Selects one member is the list. Negative indices count from the end of the list, starting with -1 for the last element in the list. An out of bounds index is not an error; it produces the value None. None - A list slice.

Since it is common for resource instances to be sparse it is not an error if a key is not present in a particular resource instance, or if an index does not match the resource type. Args: resource_obj: The resource object possibly containing a value for key. resource_key: Ordered list of key names/indices, applied left to right. Each element in the list may be one of: str - A resource property name. This could be a class attribute name or a dict index. int - A list index. Selects one member is the list. Negative indices count from the end of the list, starting with -1 for the last element in the list. An out of bounds index is not an error; it produces the value None. None - A list slice. Selects all members of a list or dict like object. A slice of an empty dict or list is an empty dict or list. default: Get() returns this value if key is not in resource. Returns: The value, None if any of the given keys are not found. This is intentionally not an error.

This function is called to evaluate a global restriction on a resource.
