Hi Robert,
I have gone through the documentation. Below is the list of things I did for serialization and deserialization.
- Define serialize function in the class whose instances I wish to serialize. In my example it is ObjectNew which has pointers of type Bar_A and Foo_A. Both are base classes and the pointers of these pointers point to instances of theri derived classes. So I have serialize function defined for Bar_A, Foo_A and all their derived classes (which includes Foo_C, Foo_D, Bar_B, Bar_C).
- Call to boost::serialization::base_object in the serialize function of derived classes which in turn calls serialize function of the corresponding base classes.
- For classes with non-defualt constructor, I have over-ridden save_construct_data and load_construct_data functions.
- Registering derived classes whose instances are pointed by pointers with types of their base classes using BOOST_CLASS_EXPORT.
- And finally use boost::archive::text_oarchive and boost::archive::text_iarchive for serialization and deserialization.
Please let me know if I have missed something or I am doing something wrong.

Have you read the documentation?
