## Detailed Description

### template <class T_arg1, class T_arg2, class T_arg3, class T_arg4, class T_return>
class sigc::pointer_functor4< T_arg1, T_arg2, T_arg3, T_arg4, T_return >

pointer_functor4 wraps existing non-member functions with 4 argument(s).

Use the convenience function ptr_fun() to create an instance of pointer_functor4.

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_arg3 Argument type used in the definition of operator()().
- T_arg4 Argument type used in the definition of operator()().
- T_return The return type of operator()().

## Member Function Documentation

template <class T_arg1, class T_arg2, class T_arg3, class T_arg4, class T_return>

T_return sigc::pointer_functor4<T_arg1, T_arg2, T_arg3, T_arg4, T_return>::operator() | ( | typename type_trait<T_arg1>::take | _A_a1,
|  | typename type_trait<T_arg2>::take | _A_a2,
|  | typename type_trait<T_arg3>::take | _A_a3,
|  | typename type_trait<T_arg4>::take | _A_a4 |
| ) |  |  | const`[inline]`

Execute the wrapped function.

Parameters:

  | _A_a1 | Argument to be passed on to the function.
  | _A_a2 | Argument to be passed on to the function.
  | _A_a3 | Argument to be passed on to the function.
  | _A_a4 | Argument to be passed on to the function.

Returns:
  The return value of the function invocation.
