## Detailed Description

### template<class T_functor>
struct sigc::hide_functor< 6, T_functor >

Adaptor that adds a dummy parameter to the wrapped functor.

This template specialization ignores the value of the 6th parameter in operator()().

## Constructor & Destructor Documentation

template <class T_functor >

sigc::hide_functor< 6, T_functor >::hide_functor | ( | const T_functor & | _A_func | ) | `[inline, explicit]`

Constructs a hide_functor object that adds a dummy parameter to the passed functor.

Parameters:

  _A_functor | Functor to invoke from operator()().

| ) |  | `[inline]`

Invokes the wrapped functor, ignoring the 7th argument.

Parameters:

  _A_arg1 | Argument to be passed on to the functor.
  _A_arg2 | Argument to be passed on to the functor.
  _A_arg3 | Argument to be passed on to the functor.
  _A_arg4 | Argument to be passed on to the functor.
  _A_arg5 | Argument to be passed on to the functor.
  _A_arg6 | Argument to be passed on to the functor.
  _A_arg7 | Argument to be ignored.

Returns:
  The return value of the functor invocation.
