Re: [protobuf] default value for a message

[Jason Hsueh]

No, default values for a message are not supported. Field defaults must be defined directly within the enclosing message - otherwise you'd need different versions of the generated class depending on the context.

Hi Everyone,
     I have looked around the documentation. But I could not find anything that implies If I can specify a set of default values for a message if all its fields are optional. As an example

message Class {
      optional uint32  aaa;
      optional uint32  bbb;
      optional uint32  ccc;
}

message Instance {
      message Class instance1 [default.aaa=11; default.bbb=22; default.ccc=33]
      message Class instance2 [default.aaa=77; default.bbb=88; default.ccc=99]
}

Here I want to treat the "message Class" as a template/Class for declaring default values for each instance of the template.
If it is not possible to declare default values like above, can anyone please suggest a way to achieve the same.


Hope I am clear in my explanation.
Thanks in advance.
JP
