addListener

public void addListener(InvalidationListener listener)

Description copied from interface: Observable

Adds an InvalidationListener which will be notified whenever the Observable becomes invalid. If the same listener is added more than once, then it will be notified more than once. That is, no check is made to ensure uniqueness.

Note that the same actual InvalidationListener instance may be safely registered for different Observables.

The Observable stores a strong reference to the listener which will prevent the listener from being garbage collected and may result in a memory leak. It is recommended to either unregister a listener by calling removeListener after use or to use an instance of WeakInvalidationListener avoid this situation.

Specified by:

addListener in interface Observable

Parameters:

listener - The listener to register

See Also:

Observable.removeListener(InvalidationListener)

removeListener

public void removeListener(InvalidationListener listener)

Description copied from interface: Observable

Removes the given listener from the list of listeners, that are notified whenever the value of the Observable becomes invalid.

If the given listener has not been previously registered (i.e. it was never added) then this method call is a no-op. If it had been previously added then it will be removed. If it had been added more than once, then only the first occurrence will be removed.

Specified by:

removeListener in interface Observable

Parameters:

listener - The listener to remove

See Also:

Observable.addListener(InvalidationListener)

addListener

public void addListener(SetChangeListener<? super E> listener)

Description copied from interface: ObservableSet

Add a listener to this observable set.

Specified by:

addListener in interface ObservableSet<E>

Parameters:

listener - the listener for listening to the set changes

removeListener

public void removeListener(SetChangeListener<? super E> listener)

Description copied from interface: ObservableSet

Tries to removed a listener from this observable set. If the listener is not attached to this list, nothing happens.

Specified by:

removeListener in interface ObservableSet<E>

Parameters:

listener - a listener to remove
