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

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
funcFunctor to invoke from operator()().
boundArgument to bind to the functor.

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
argArguments to be passed on to the functor.
Returns
The return value of the functor invocation.
