Detailed Description

template<typename T_functor, typename... T_type>
struct sigc::retype_functor< T_functor, T_type >

Adaptor that performs C-style casts on the parameters passed on to the functor.

The following template arguments are used:

  • T_functor Type of the functor to wrap.
  • T_type Types of T_functor's arguments.
