java.lang.Object
- edu.uci.ics.jung.algorithms.layout.LayoutDecorator<V,E>
- - edu.uci.ics.jung.visualization.layout.ObservableCachingLayout<V,E>

All Implemented Interfaces:

edu.uci.ics.jung.algorithms.layout.Layout<V,E>, edu.uci.ics.jung.algorithms.util.IterativeContext, Caching, ChangeEventSupport, org.apache.commons.collections4.Transformer<V,java.awt.geom.Point2D>

Direct Known Subclasses:

PersistentLayoutImpl
```
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.
