## 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.
