Is it expected that the calls to register_type need to be identical on both the save and load side of a serialization exchange?
It is required.
I thought I read that the registration facility sets up a map.
It does. But the mapping has to be loaded in the order it was created
But the following caused a archive_exception.
struct C {}; struct B : C {}; struct A : B {};
--- save
boost::archive::text_oarchive oa(some_ostream);
oa.register_type(static_cast<A*>(0)); oa.register_type(static_cast<B*>(0)); oa.register_type(static_cast<C*>(0));
oa & aC_ptr;
--- load
boost::archive::text_iarchive ia(some_istream);
ia.register_type(static_cast<B*>(0)); ia.register_type(static_cast<A*>(0)); ia.register_type(static_cast<C*>(0));
oa & aC_ptr;
Thanks, Jeff
