The question is not the name of the method, the problem is the additional
parameter which boost::serialization cannot pass to me. For this reason I
have to call my own serialize method inside the standard serialize method
prepared for boost::serialization.

 

template<class TArchiveType>

MyContainer::serialize(TArchiveType &rArchive, const unsigned int Version)

{

   p_variable_data->MyCustomSerialize(rArchive, Version, MyData);

}

 

NOTE that I have a pointer to the base calss and I have to call the
MyCustomSerialize of the derive class. For doing this I have to simulate the
mechanism already used in boost::serialization to call the standard
serialization. The problem is that I don’t know how to use the
get_extended_info and its related interface.

 

Thanks again.

 

Pooyan.

Just rename MyCostumeSerialize to serialize
