Method Summary

Modifier and TypeMethod and Description
public void
addListener(InvalidationListener listener)

Implements javafx.beans.Observable.addListener.

Adds an InvalidationListener which will be notified whenever the Observable becomes invalid.

public void
addListener(ChangeListener<? super ObservableList<E>> listener)

Implements javafx.beans.value.ObservableValue.addListener.

Adds a ChangeListener which will be notified whenever the value of the ObservableValue changes.

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

Implements javafx.collections.ObservableList.addListener.

Add a listener to this observable list.

protected void
fireValueChangedEvent()

This method needs to be called if the reference to the javafx.collections.ObservableList changes.

protected void
fireValueChangedEvent(ListChangeListener.Change<? extends E>
the change that needs to be propagated
change)

This method needs to be called if the content of the referenced javafx.collections.ObservableList changes.

public void
removeListener(InvalidationListener listener)

Implements javafx.beans.Observable.removeListener.

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

public void addListener(InvalidationListener listener)

Implements javafx.beans.Observable.addListener.

Doc from javafx.beans.Observable.addListener.

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.

Implements javafx.beans.value.ObservableValue.addListener.

Doc from javafx.beans.value.ObservableValue.addListener.

Adds a ChangeListener which will be notified whenever the value of the ObservableValue changes. 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 ChangeListener instance may be safely registered for different ObservableValues.

The ObservableValue 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 WeakChangeListener avoid this situation.

@Override
fireValueChangedEventback to summary
protected void fireValueChangedEvent()

This method needs to be called if the reference to the javafx.collections.ObservableList changes. It sends notifications to all attached InvalidationListeners, ChangeListeners, and javafx.collections.ListChangeListener. This method needs to be called, if the value of this property changes.

fireValueChangedEventback to summary
protected void fireValueChangedEvent(ListChangeListener.Change<? extends E> change)

This method needs to be called if the content of the referenced javafx.collections.ObservableList changes. Sends notifications to all attached InvalidationListeners, ChangeListeners, and javafx.collections.ListChangeListener. This method is called when the content of the list changes.

Parameters
change:ListChangeListener.Change<? extends E>

the change that needs to be propagated

public void removeListener(InvalidationListener listener)

Implements javafx.beans.Observable.removeListener.

Doc from javafx.beans.Observable.removeListener.

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.
