The easiest way to use this class is if you have access to the FileDescriptor protos containing the messages you want to create you can just do the following: message_classes = message_factory.GetMessages(iterable_of_file_descriptors) my_proto_instance = message_classes['some.proto.package.MessageName']() z"matthewtoia@google.com (Matt Toia)é)Úapi_implementation)Údescriptor_pool)ÚmessageÚcpp)Ú cpp_message)Úpython_messagec@s2eZdZdZd dd„Zdd„Zdd„Zd d „ZdS) ÚMessageFactoryz@Factory for creating Proto2 messages from descriptors in a pool.NcCs|p t ¡|_i|_dS)zInitializes a new factory.N)rÚDescriptorPoolÚpoolÚ_classes)Úselfr ©r ú[/var/www/html/django/DPS/env/lib/python3.9/site-packages/google/protobuf/message_factory.pyÚ__init__;szMessageFactory.__init__cCs,||jvr"| |¡}||j|<|S|j|S)aEObtains a proto2 message class based on the passed in descriptor.

Don't call this function directly, it always creates a new class. Call GetPrototype() instead. This method is meant to be overridden in subblasses to perform additional operations on the newly constructed class. Args: descriptor: The descriptor to build from.
