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*. z#robinson@google.com (Will Robinson)� )�BytesION)�api_implementation)� containers)�decoder)�encoder)�enum_type_wrapper)�message_listener)� type_checkers)�well_known_types)� wire_format)� descriptor)�message)� text_formatzgoogle.protobuf.Anyc s0 e Zd ZdZdZ� fdd�Z� fdd�Z� ZS )� GeneratedProtocolMessageTypeaQ 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 ... � DESCRIPTORc sZ |t j }|jtjkr(|tj|j f7 }t||� t||� tt | �}|j| |||�}|S )a 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).
