Package org.jungrapht.visualization.layout.model

Class DefaultLayoutModel<V>

java.lang.Object

org.jungrapht.visualization.layout.model.AbstractLayoutModel<V>

org.jungrapht.visualization.layout.model.DefaultLayoutModel<V>

Type Parameters:

V - the vertex type

All Implemented Interfaces:

Function<V,Point>, LayoutSizeChange.Producer<V>, LayoutStateChange.Producer, LayoutVertexPositionChange.Listener<V>, LayoutVertexPositionChange.Producer<V>, ModelChange.Producer, ViewChange.Producer, LayoutModel<V>, Caching

public class DefaultLayoutModel<V>
extends AbstractLayoutModel<V>
implements LayoutModel<V>, Caching

A LayoutModel that uses a ConcurrentHashMap. Values not already in the Map are loaded with an initializer and computeIfAbsent.
