Trait that specifies the return type of any type.
Template specializations for functors derived from sigc::functor_base, for other functors whose result type can be deduced with decltype(), for function pointers and for class methods are provided.
T_functor | Functor type. |
I_derives_functor_base | Whether T_functor inherits from sigc::functor_base. |
I_can_use_decltype | Whether the result type of T_functor can be deduced with decltype(). |
using sigc::functor_trait< T_functor, I_derives_functor_base, I_can_use_decltype >::functor_type = T_functor |
using sigc::functor_trait< T_functor, I_derives_functor_base, I_can_use_decltype >::result_type = void |
