Protocol Buffer Basics: Python

[amlitt4]

The code snippet referenced in section "The Protocol Buffer API" is no longer accurate. Section should be updated to reflect how latest python code is compiled. meta_class is no longer used.

The previous code snippet: class Person(message.Message): metaclass = reflection.GeneratedProtocolMessageType

class PhoneNumber(message.Message): metaclass = reflection.GeneratedProtocolMessageType DESCRIPTOR = _PERSON_PHONENUMBER DESCRIPTOR = _PERSON

class AddressBook(message.Message): metaclass = reflection.GeneratedProtocolMessageType DESCRIPTOR = _ADDRESSBOOK
