## Detailed Description

### template<typename T_setter, typename T_getter1, typename 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 <typename T_setter , typename T_getter1 , typename T_getter2 >

sigc::compose2_functor< T_setter, T_getter1, T_getter2 >::compose2_functor | ( | const T_setter & | setter,
|  | const T_getter1 & | getter1,
|  | const T_getter2 & | getter2
| ) |  |
| inline

Constructs a compose2_functor object that combines the passed functors.

Parameters

  setter | Functor that receives the return values of the invocation of getter1 and getter2.
  getter1 | Functor to invoke from operator()().
  getter2 | Functor to invoke from operator()().
