I agree with Marc. When things get complicated, it's a good idea to separate your tasks. It seems like your java class, which generates some of the data based on other data, is one issue, and your serialization is a separate issue. (I know it would be nice to just make that class serializable, but that may be where you make things complicated.)
When I want to serialize my classes with protobufs, I create a separate protobuf object to just handle serialization. Then I create a utility class that transfers data between my protobuf object and my java class. Then it's easy to add a constructor to my java class that takes a protobuf object and defers the work to the utility class. When I transfer data using protobufs, I don't convert to the protobuf format until the last possible moment before sending, and I immediately convert to the java class on receiving data. That lets me put my protobuf objects behind a facade, so I don't need to know the serialization details. -- Miguel Muñoz On Jun 15, 7:07 am, "gabor.dicso" <gabor.di...@gmail.com> wrote: > Hi all, > > I would like to be able to serialize primitive types platform- > independently.
