Detailed Description
template <class T_base, class T_derived>
struct sigc::is_base_and_derived< T_base, T_derived >
Compile-time determination of base-class relationship in C++ (adapted to match the syntax of boost's type_traits library).
Use this to provide a template specialization for a set of types. For instance,
template <class T_thing, bool Tval_derives_from_something = sigc::is_base_and_derived<Something, T_thing>::value> class TheTemplate { //Standard implementation. }
//Specialization for T_things that derive from Something (Tval_derives_from_something is true) template <class t_thing>=""> class TheTemplate<T_thing, true> { T_thing thing; thing.method_that_is_in_something(); }
