Re: [Boost-users] Feature request for serialization

This would be something that would be better to do yourself.  Here is a 
suggestion:

Suppose you've got

class A {
    B b;
    C c;
    D d;
};

and

class B {
    std::vector<E> ve;
};

Suppose you want a call back every time something is serialized

template<class Archive>
void serialize(Archive & ar, E & e, const unsigned int version){
    ar & e;
    my_callback_e(); //
}

template<class Archive>
void serialize(Archive & ar, B & b, const unsigned int version){
    ar & b;
    my_callback_b(); //
}

etc.

If you wanted something more generc, you could make an archive
adaptor which could add the same functionalty to any archive.
