示例1: testTopLevelExtensionsForOptionalMessage
# 需要導入模塊: from google.protobuf import unittest_pb2 [as 別名]
# 或者: from google.protobuf.unittest_pb2 import optional_foreign_message_extension [as 別名]

# As with normal (non-extension) fields, merely reading from the
# thing shouldn't set the "has" bit.

extendee_proto.Extensions[extension].c = 23
self.assertEqual(23, extendee_proto.Extensions[extension].c)

# Save a reference here.
