By hand. Plain C++ doesn't (at least to my knowledge) contain a way of 
serialization. If you where really stupid, you read bytes from the objects 
adress to objects address + sizeof(object). But that would give you lots of 
runtime-specific pointers and not the child data referenced by pointers. So 
don't even try to write it in code.

I don't know why you want to serialize, but you have to add the functions to 
store and restore yourself. Depending on what you want, you can add >>- and 
<<-operators or some toXml()/fromXml() functions or something like that...

Have fun,

Arnold
