## Detailed Description

template<int I_location, typename T_functor, typename... T_bound>
struct sigc::bind_functor< I_location, T_functor, T_bound >

Adaptor that binds arguments to the wrapped functor.

Use the convenience function sigc::bind() to create an instance of sigc::bind_functor.

The following template arguments are used:

- I_location Zero-based position of the argument to fix (`-1` for the last argument).
- T_bound Types of the bound argument.
- T_functor Type of the functor to wrap.

## Constructor & Destructor Documentation

## ◆ bind_functor()

template <int I_location, typename T_functor, typename... T_bound>

sigc::bind_functor< I_location, T_functor, T_bound >::bind_functor | ( | type_trait_take_t< T_functor > | func,
|  | type_trait_take_t< T_bound >... | bound )
| inline

Constructs a bind_functor object that binds an argument to the passed functor.

Parameters

  func | Functor to invoke from operator()().
  bound | Argument to bind to the functor.

## Member Function Documentation

## ◆ operator()()

template <int I_location, typename T_functor, typename... T_bound>
template <typename... T_arg>

decltype(auto) sigc::bind_functor< I_location, T_functor, T_bound >::operator() | ( | T_arg &&... | arg | ) |
| inline

Invokes the wrapped functor passing on the arguments.

bound_ is passed as the next argument.

Parameters

  arg | Arguments to be passed on to the functor.

Returns
  The return value of the functor invocation.

## Member Data Documentation

## ◆ bound_

template <int I_location, typename T_functor, typename... T_bound>

std::tuple<bound_argument<T_bound>...> sigc::bind_functor< I_location, T_functor, T_bound >::bound_

The arguments bound to the functor.
