            Selector (string) --A path selector supports easy selection of an object by the parent/child links leading to it from the directory root. Use the link names from each parent/child link to construct the path. Path selectors start with a slash (/) and link names are separated by slashes. For more information about paths, see Accessing Objects . You can identify an object in one of the following ways:
            $ObjectIdentifier - An object identifier is an opaque string provided by Amazon Cloud Directory. When creating objects, the system will provide you with the identifier of the created object. An object s identifier is immutable and no two objects will ever share the same object identifier
            /some/path - Identifies the object based on path
            #SomeBatchReference - Identifies the object in a batch call
            

    :type ConsistencyLevel: string
    :param ConsistencyLevel: The consistency level at which to retrieve the object information.
