[Boost-users] serialization: pointers to base classes

Hello,
I am unclear about registration and export.

I have this public single-derivation hierarchy

B
|   \      \
D1   D2    D3
|
D11

The 5 structs are non abstract.
I will want to serialize (save)  const B* and load it back with the
serialization lib constructing for me (on the heap) the right object.

Did I understand right that the library does this for me?
Does it construct the object on the heap?

I export the 5 structs with the macro BOOST_CLASS_EXPORT_GUID(ns::B, "B") at
global namespace level.
Do I have to register them too?

template <class Archive>
void serialize(Archive &ar, ns::B&, const unsigned int version)
{
  ar.template register_type<D1>();
  ar.template register_type<D2>();
  ar.template register_type<D3>();
  ar.template register_type<D11>();
}
or do I register for each class only the immediate derived?

regards,
