GetMessages(self, files)

source code

Gets all the messages from a specified file.

This will find and resolve dependencies, failing if the descriptor
pool cannot satisfy them.

Args:
  files: The file names to extract messages from.

Returns:
  A dictionary mapping proto names to the message classes. This will include
  any dependent messages as well as any messages defined in the same file as
  a specified message.

GetPrototype(self, descriptor)

source code

Builds a proto2 message class based on the passed in descriptor.

Passing a descriptor with a fully qualified name matching a previous
invocation will cause the same class to be returned.

Args:
  descriptor: The descriptor to build from.

Returns:
  A class describing the passed in descriptor.
