A value whose changes can be tracked by value change listeners. @noimplement This interface is not intended to be implemented by clients.Clients should instead subclass one of the classes that implement this interface. Note that direct implementers of this interface outside of the framework will be broken in future releases when methods are added to this interface. @see AbstractObservableValue @since 1.0
