Detailed Description
template<class T_return, class T_obj, class T_arg1, class T_arg2>
class sigc::mem_functor2< T_return, T_obj, T_arg1, T_arg2 >
mem_functor2 wraps methods with 2 argument(s).
Use the convenience function mem_fun() to create an instance of mem_functor2.
The following template arguments are used:
- T_arg1 Argument type used in the definition of operator()().
- T_arg2 Argument type used in the definition of operator()().
- T_return The return type of operator()().
- T_obj The object type.
