    public class ObservableCachingLayout<V,​E>
extends edu.uci.ics.jung.algorithms.layout.LayoutDecorator<V,​E>
implements ChangeEventSupport, Caching
    A LayoutDecorator that fires ChangeEvents when certain methods are called. Used to wrap a Layout so that the visualization components can be notified of changes.
