virtual tlp::Observer::~Observer () [inline, virtual]

Member Function Documentation

virtual void tlp::Observer::observableDestroyed (Observable *) [pure virtual]Methods called when an observable has been deleted. holdObservers and unHoldObservers function have no effects on this function.

virtual void tlp::Observer::update (std::set< Observable * >::iterator begin, std::set< Observable * >::iterator end) [pure virtual]Methods called when a change occur in the observed objects Due to the possibility to differs notificatiosn several objects can send a notify events simultaneously. The iterators given in parameter enable to iterate all these objects.
