Member Function Documentation

_detachAllObservers()

void Arcane::Observable::_detachAllObservers ( )

protected

Definition at line 87 of file Observable.cc.

attachObserver()

void Arcane::Observable::attachObserver ( IObserver * obs )

overridevirtual

Attaches the observer obs to this observable.

It is possible to attach an observer more than once.

Implements Arcane::IObservable.

Definition at line 40 of file Observable.cc.

References Arcane::IObserver::attachToObservable().

Here is the call graph for this function:

detachAllObservers()

void Arcane::Observable::detachAllObservers ( )

overridevirtual

Detaches all observers associated with this instance.

Implements Arcane::IObservable.

Definition at line 100 of file Observable.cc.

detachObserver()

void Arcane::Observable::detachObserver ( IObserver * obs )

overridevirtual

Detaches the observer obs from this observable.

If the observer obs is not present, nothing happens. If it is present multiple times, the last occurrence is deleted.

Implements Arcane::IObservable.

Definition at line 53 of file Observable.cc.

hasObservers()

bool Arcane::Observable::hasObservers ( ) const

overridevirtual

True if observers are attached to this observable.

Implements Arcane::IObservable.

Definition at line 78 of file Observable.cc.

notifyAllObservers()

void Arcane::Observable::notifyAllObservers ( )

overridevirtual

Notifies all observers.

For each attached observer, calls IObserver::observerUpdate().

Implements Arcane::IObservable.

Definition at line 66 of file Observable.cc.
