## Detailed Description

### template <class T_functor>
struct sigc::adapts< T_functor >

Base type for adaptors.

adapts wraps adaptors, functors, function pointers and class methods. It contains a single member functor which is always a sigc::adaptor_base. The typedef adaptor_type defines the exact type that is used to store the adaptor, functor, function pointer or class method passed into the constructor. It differs from T_functor unless T_functor inherits from sigc::adaptor_base.

Example of a simple adaptor:

         template <T_functor>
         struct my_adpator : public sigc::adapts<T_functor>
         {
           template <class T_arg1=void, class T_arg2=void>
           struct deduce_result_type
           { typedef typename sigc::deduce_result_type<T_functor, T_arg1, T_arg2>::type type; };
           typedef typename sigc::functor_trait<T_functor>::result_type result_type;

           result_type
           operator()() const;

           template <class T_arg1>
           typename deduce_result_type<T_arg1>::type
           operator()(T_arg1 _A_arg1) const;

           template <class T_arg1, class T_arg2>
           typename deduce_result_type<T_arg1, T_arg2>::type
           operator()(T_arg1 _A_arg1, class T_arg2) const;

           explicit adaptor_functor(const T_functor& _A_functor) // Constructs a my_functor object that wraps the passed functor.
             : sigc::adapts<T_functor>(_A_functor) {}

           mutable T_functor functor_; // Functor that is invoked from operator()().
         };
