Description:
 def DEFINE_multi_enum_class( # pylint: disable=invalid-name,redefined-builtin name, default, enum_class, help, flag_values=_flagvalues.FLAGS, module_name=None, **args):
 """Registers a flag whose value can be a list of enum members. Use the flag on the command line multiple times to place multiple enum values into the list. Args: name: str, the flag name. default: Union[Iterable[Enum], Iterable[Text], Enum, Text, None], the default value of the flag; see `DEFINE_multi`; only differences are documented here. If the value is a single Enum, it is treated as a single-item list of that Enum value. If it is an iterable, text values within the iterable will be converted to the equivalent Enum objects. enum_class: class, the Enum class with all the possible values for the flag. help: str, the help message. flag_values: FlagValues, the FlagValues instance with which the flag will be registered. This should almost never need to be overridden. module_name: A string, the name of the Python module declaring this flag. If not provided, it will be computed using the stack trace of this call. **args: Dictionary with extra keyword args that are passed to the Flag __init__. """
