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 (
-1for the last argument). - T_bound Types of the bound argument.
- T_functor Type of the functor to wrap.

◆ bind_functor()
template <int I_location, typename T_functor , typename... T_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>
|
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.
