Can you please explain me more the idea of extradata structure? Consider that my extradata can be a double, ublas::vector, or even std::vector<weak_ptr<Element> > or any new type of variables. I have:
std::vector<std::pair<VariableData, extradata> > mData ... ar << mData;
and each element of vector can have a different type of data with different size or even have pointers. (It's a heterogeneous container)
The above will work as written. Maybe what you want is: template<class T> class mytype : std::vector<std::pair<VariableData, T> > { template<class Archive> void serialize(Archive &ar, const unsigned int version){ ar << boost::serialization::base_object(*this); } }; then you can mytype<double> m_t ... ar << m_t The possibilities are endless. This really isn't about the serialization library but about C++ Robert Ramey
