public class CachingLayout<V,E>
extends LayoutDecorator<V,E>
implements Caching

A LayoutDecorator that caches locations in a clearable Map. This can be used to ensure that edge endpoints are always the same as vertex locations when they are drawn in the render loop during the time that the layout's relaxer thread is changing the locations.
