To clarify the default value a bit: In your code, if you don't set_somefield() explicitly: 1) has_somefield() will return false. 2) somefield() will return the default value. 3) the default value won't be serialized into the wire. that said, if you don't set any field in your message, the serialized bytes will be empty. Each field has a default value, e.g. 0 for int, "" for string. You can override the default value by set [default=xxx] in the .proto file, but it won't change the behavior described above. > > 2.Can we not specify default values for repeated fields too???
