addListener back to summary

addListener	back to summary
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. Annotations @Override
