I just discovered the serialization library found it extremely nice and useful. I appreciate all work of the author. I have not yet build any program with the library, I just read the documentation. There is one think that do not fit to my use: "typeid information is not included in archives". The reason is "archive portability" and the solution "same sequence by save/load". But what if I do not know the sequence? What can I do then? Think about a CAD program. I do not know what the user will draw, a line, circle, rectangle and so on. And I have to save them in a file, at the load I need to know what type of object do I load. For me the "archive portability" is not so important. Is there a way to configure/change the library to save the name of the class specified by std::type_of::name() in the archive?
I am doing something very similar to what you mention above. What I do is to store pointers to the objects (shared_ptr actually) as base class ptrs in the archive. When I read the archive in, I do a dynamic_cast, and I get the original object back - works very well. I haven't used typeid, so it is possible that I haven't understood your question... Mahesh
