## Detailed Description

### template <class T_arg1, class T_return>
class sigc::pointer_functor1< T_arg1, T_return >

pointer_functor1 wraps existing non-member functions with 1 argument(s).

Use the convenience function ptr_fun() to create an instance of pointer_functor1.

The following template arguments are used:

- T_arg1 Argument type used in the definition of operator()().
- T_return The return type of operator()().

## Constructor & Destructor Documentation

template <class T_arg1, class T_return>
sigc::pointer_functor1<T_arg1, T_return>::pointer_functor1 | ( |  | ) | `[inline]`

| Constructs an invalid functor.

template <class T_arg1, class T_return>
sigc::pointer_functor1<T_arg1, T_return>::pointer_functor1 | ( | function_type | _A_func | ) | `[inline, explicit]`

  | Constructs a pointer_functor1 object that wraps an existing function. Parameters:
  | _A_func | Pointer to function that will be invoked from operator()().

## Member Function Documentation

template <class T_arg1, class T_return>
T_return sigc::pointer_functor1<T_arg1, T_return>::operator() | ( | typename type_trait<T_arg1>::take | _A_a1 | ) | const`[inline]`

  | Execute the wrapped function. Parameters:
  | _A_a1 | Argument to be passed on to the function.
Returns: The return value of the function invocation.
