const_mem_functor2 wraps const methods with 2 argument(s).
Use the convenience function mem_fun() to create an instance of const_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.
