At the moment I am working with XML serialization of Boost. I am serializing my own classes which works well. But my objects are changing often, for example:

class Modul { public: setValue(int); private: int Value; }

Modul* M = new Modul();

Now I wanna serialize M every time Value changes, so that I can save a complete history of changes on M. But M is serialized only once, after that I get this in my XML, although Value has changed:

<Modul class_id_reference="1" object_id_reference="_2"></Modul>

This is unusable for my purpose, so how can I stop that kind of "linking" and serialize the Objekt every time completely?

look at serialization traits - tracking. This lets you suppress object tracking on a per/class basis. Robert Ramey
