Detailed Description

This file defines 4 macros to assist with explicitly declaring to the Boost Serialization library when a class is abstract. The interface for doing this changed in Boost 1.36.0, hence this wrapper.

The easy case is for a non-templated class. For example, if you have a class called AbstractClass, use CLASS_IS_ABSTRACT(AbstractClass)

For classes templated over either 1 or 2 unsigned parameters, there are helper macros TEMPLATED_CLASS_IS_ABSTRACT_1_UNSIGNED and TEMPLATED_CLASS_IS_ABSTRACT_2_UNSIGNED. For example, with a class template<unsigned SPACE_DIM, unsigned ELEMENT_DIM> class AbstractTemplatedClass { ... }; use TEMPLATED_CLASS_IS_ABSTRACT_2_UNSIGNED(AbstractTemplatedClass)

For a general templated class, you have to do a little extra work. For example, with a class template<class C, unsigned U> class AbstractTemplatedClass { ... }; use namespace boost { namespace serialization { template<class C, unsigned U> struct is_abstract<AbstractTemplatedClass<C, U> > TEMPLATED_CLASS_IS_ABSTRACT_DEFN template<class C, unsigned U> struct is_abstract<const AbstractTemplatedClass<C, U> > TEMPLATED_CLASS_IS_ABSTRACT_DEFN }}
