Class ObjectPropertyBase<T>

public ObjectPropertyBase()

The constructor of the ObjectPropertyBase.

public ObjectPropertyBase(T initialValue)

The constructor of the ObjectPropertyBase.

public void addListener(InvalidationListener listener)

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.

public void removeListener(InvalidationListener listener)

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.

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

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(ChangeListener<? super T> listener)

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

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.

protected void fireValueChangedEvent()

Sends notifications to all attached InvalidationListeners and ChangeListeners. This method is called when the value is changed, either manually by calling set(T) or in case of a bound property, if the binding becomes invalid.

protected void invalidated()

The method invalidated() can be overridden to receive invalidation notifications. This is the preferred option in Objects defining the property, because it requires less memory. The default implementation is empty.

public T get()

Returns the current value of this ObservableObjectValue<T>.

public void set(T newValue)

Set the wrapped value. Should be equivalent to WritableValue.setValue(java.lang.Object)

public boolean isBound()

Can be used to check, if a Property is bound.

public void bind(ObservableValue<? extends T> newObservable)

Create a unidirection binding for this Property.

Note that JavaFX has all the bind calls implemented through weak listeners. This means the bound property can be garbage collected and stopped from being updated.

public void unbind()

Remove the unidirectional binding for this Property. If the Property is not bound, calling this method has no effect.

public String toString()

Returns a string representation of this ObjectPropertyBase object.
