const_limit_reference object for a class that derives from trackable.
sigc::const_limit_reference< T_type, true >::const_limit_reference | ( | const T_type & | _A_target | ) | [inline] |
Constructor.
_A_target | The reference to limit. |
const T_type& sigc::const_limit_reference< T_type, true >::invoke | ( | ) | const [inline] |
Retrieve the reference.
This is always a reference to the derived instance.
const trackable& sigc::const_limit_reference< T_type, true >::visit | ( | ) | const [inline] |
Retrieve the entity to visit for visit_each().
Depending on the template specialization, this is either a derived reference, or sigc::trackable& if T_type derives from sigc::trackable.
