_activity_logging_world_list()

dart_utilities._activity_logging_world_list (   member,   access_type = None  )

Returns a set of world suffixes for which a definition member has activity logging, for specified access type.

access_type can be 'Getter' or 'Setter' if only checking getting or setting.
