Detailed Description
template<typename T_functor>
struct sigc::visitor< T_functor >
sigc::visitor<T_functor>::do_visit_each() performs a functor on each of the targets of a functor.
All unknown types just call action on them. Add specializations that specialize the T_functor argument for your own functor types, so that subobjects get visited. This is needed to enable auto-disconnection support for your functor types.
- Example:
- namespace some_ns{struct some_functor{void operator()() {}some_possibly_sigc_trackable_derived_type some_data_member;some_other_functor_type some_other_functor;};}namespace sigc{template <>struct visitor<some_ns::some_functor>{template <typename T_action>const some_ns::some_functor& target){sigc::visit_each(action, target.some_data_member);sigc::visit_each(action, target.some_other_functor);}};}
