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))api_implementation)messageZcpp) cpp_message)python_messagecCst|}|}|j||S)zGenerate a new Message instance from this Descriptor and a byte string.

Composite descriptors are handled by defining the new class as a member of the parent class, recursing as deep as necessary.
