## Detailed Description

### template<class T_setter, class T_getter1, class T_getter2>
struct sigc::compose2_functor< T_setter, T_getter1, T_getter2 >

Adaptor that combines three functors.

Use the convenience function sigc::compose() to create an instance of sigc::compose2_functor.

The following template arguments are used:

- T_setter Type of the setter functor to wrap.
- T_getter1 Type of the first getter functor to wrap.
- T_getter2 Type of the second getter functor to wrap.

## Constructor & Destructor Documentation

template <class T_setter , class T_getter1 , class T_getter2 >

sigc::compose2_functor< T_setter, T_getter1, T_getter2 >::compose2_functor | ( | const T_setter & | _A_setter,
|  | const T_getter1 & | _A_getter1,
|  | const T_getter2 & | _A_getter2
| ) |  | `[inline]`

Constructs a compose2_functor object that combines the passed functors.

Parameters:

  _A_setter | Functor that receives the return values of the invokation of _A_getter1 and _A_getter2.
  _A_getter1 | Functor to invoke from operator()().
  _A_getter2 | Functor to invoke from operator()().
