Class RadiusGraphElementAccessor<V,E>

java.lang.Object
  edu.uci.ics.jung.algorithms.layout3d.RadiusGraphElementAccessor<V,E>

All Implemented Interfaces:

GraphElementAccessor<V,E>

public class RadiusGraphElementAccessor<V,E>
extends Object
implements GraphElementAccessor<V,E>

Simple implementation of PickSupport that returns the vertex or edge that is closest to the specified location. This implementation provides the same picking options that were available in previous versions of AbstractLayout.

No element will be returned that is farther away than the specified maximum distance.

Method Detail

getVertex

public V getVertex(Layout<V,E> layout,
                   javax.vecmath.Point3f p)

Gets the vertex nearest to the location of the (x,y) location selected, within a distance of maxDistance. Iterates through all visible vertices and checks their distance from the click. Override this method to provde a more efficient implementation.

Specified by:

getVertex in interface GraphElementAccessor<V,E>
