Method Summary

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

Implements javafx.beans.Observable.addListener.

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

public void
addListener(ChangeListener<? super T> observer)

Implements javafx.beans.value.ObservableValue.addListener.

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

public T
get()

Implements javafx.beans.value.ObservableObjectValue.get.

Returns the current value of this ObservableObjectValue<T>.

public T
getValue()

Implements javafx.beans.value.ObservableValue.getValue.

Returns the current value of this ObservableValue

public void
removeListener(InvalidationListener observer)

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
removeListener(ChangeListener<? super T> observer)

Implements javafx.beans.value.ObservableValue.removeListener.

Removes the given listener from the list of listeners that are notified whenever the value of the ObservableValue changes.

public void addListener(InvalidationListener observer)

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.

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.

public void removeListener(InvalidationListener observer)

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.
