This module defines type checking utilities in the forms of dictionaries: VALUE_CHECKERS: A dictionary of field types and a value validation object. TYPE_TO_BYTE_SIZE_FN: A dictionary with field types and a size computing function. TYPE_TO_SERIALIZE_METHOD: A dictionary with field types and serialization function. FIELD_TYPE_TO_WIRE_TYPE: A dictionary with field typed and their coresponding wire types. TYPE_TO_DESERIALIZE_METHOD: A dictionary with field types and deserialization function. s# robinson@google.com (Will Robinson)i����N( t api_implementation( t decoder( t encoder( t wire_format( t descriptorc C s | j j d k S( Nt proto3( t containing_typet syntax( t field_descriptor( ( sJ /usr/lib/python2.7/site-packages/google/protobuf/internal/type_checkers.pyt SupportsOpenEnums> s c C so | j t j k r+ | j t j k r+ t � S| j t j k rd t | � rT t t j St | j � Sn t | j S( s Returns a type checker for a message field of the specified types.
