[Boost-users] [serialization] how for a particular object to get ID that is assigned by the lib

17 Aug 2005

      Hi,

How could I determine the objectID of an object after it's been saved?
I mean the ID that boost::serialization generates for each object at saving.
In other words - I know the address of the object and I would like to 
get its ID after it's been saved.
Does anyone know how to do that?
Example follows at the end.

#include <boost/archive/text_oarchive.hpp>

class A {
    template<class Archive>
    void serialize(Archive & ar, const unsigned int version)
    {   ar & i;
    }
public:
     int i;|
};

int main()
{
    std::ofstream ofs("filename");
    boost::archive::text_oarchive oa(ofs);

    A a; a.i = 1;
    oa & a;
    // need ID of *a* here !!!
}
