Hello,
I have a base class and a large number of derived classes that are all adapted as fusion sequences.
The intention is to serialize through the base pointer.
struct Base; struct D_1 : public Base;struct D_2 : public Base;...
All the D_i are adapted as fusion sequences. Besides, there is an mpl vector of all the D_i called DVECTOR.
In a normal setting, I would have written this:
template <typename Archive>void serialize(Archive& ar, Base& b, unsigned int ){ ar & b.member1;}
template <typename Archive>void serialize(Archive& ar, D1& d, unsigned int ){ ar & boost::serialization::base_object<Base>(d); ar & d.memberd1;}BOOST_CLASS_EXPORT_KEY(D1)
and the same for all D_i. Then I would need BOOST_CLASS_EXPORT_IMPLEMENT for all the D_i as well in the relevant translation units.
The base_object part of serialize() is the same for all D_i
The D_i specific part of serialize(), I have the ability to generate with fusion meta functions.
This leads to a template function with 2 template arguments:
