protocol buffers are dumb data containers, as such they don't have logic 
(methods, etc ...), so you can't build an object oriented system on them.

As far as I am concerned, protobuf are just a way to structure data and 
transfer it to various languages. So for example if you serialize a 
message in R (with RProtoBuf) and deserialize it in java, you get the 
same data.

Does that help ?
