Recall that a metaclass is the "type" of a class. (A class is to a metaclass what an instance is to a class.) In this case, we use the GeneratedProtocolMessageType metaclass to inject all the useful functionality into the classes output by the protocol compiler at compile-time. The upshot of all this is that the real implementation details for ALL pure-Python protocol buffers are *here in this file*. s# robinson@google.com (Will Robinson)i����( t BytesION( t api_implementation( t containers( t decoder( t encoder( t enum_type_wrapper( t message_listener( t type_checkers( t well_known_types( t wire_format( t descriptor( t message( t text_formats google.protobuf.Anyt GeneratedProtocolMessageTypec B s& e Z d Z d Z d � Z d � Z RS( sQ Metaclass for protocol message classes created at runtime from Descriptors. We add implementations for all methods described in the Message class. We also create properties to allow getting/setting all fields in the protocol message. Finally, we create slots to prevent users from accidentally "setting" nonexistent fields in the protocol message, which then wouldn't get serialized / deserialized properly. The protocol compiler currently uses this metaclass to create protocol message classes at runtime. Clients can also manually create their own classes at runtime, as in this example: mydescriptor = Descriptor(.....) factory = symbol_database.Default() factory.pool.AddDescriptor(mydescriptor) MyProtoClass = factory.GetPrototype(mydescriptor) myproto_instance = MyProtoClass() myproto.foo_field = 23 ... t DESCRIPTORc C s~ | t j } | j t j k r9 | t j | j f 7} n t | | � t | | � t t | � } | j | | | | � } | S( s Custom allocation for runtime-generated class types. We override __new__ because this is apparently the only place where we can meaningfully set __slots__ on the class we're creating(?). (The interplay between metaclasses and slots is not very well-documented). Args: name: Name of the class (ignored, but required by the metaclass protocol). bases: Base classes of the class we're constructing. (Should be message.Message). We ignore this field, but it's required by the metaclass protocol dictionary: The class dictionary of the class we're constructing. dictionary[_DESCRIPTOR_KEY] must contain a Descriptor object describing this protocol message type.
