Hi,
This question is regarding inheritance in protobuf C++ library. I will
explain what I am looking for with a concrete example.
I have this message definition:
message MSG1
{
required string account = 0;
required string symbol = 1;
}
Now I want to extend this message and define a new message like this:
message MSG2
{
required string account = 0;
required string symbol = 1;
required int32 id = 2;
}
You will notice that first two fields of MSG2 are exactly same as MSG1
(they are intended to be like that). But here I had to copy paste the
common fields again.
Can I do something like this?
message MSG2 extends MSG1
{
required int32 id = 2;
}
I have already thought about using it like:
message MSG2
{
required MSG1 msg1 = 0;
required int32 id = 2;
}
But this is not really what I want.
What's the best way to achieve this?
Thanks,
Saurabh
