Class RandomLocationTransformer<V>

java.lang.Object

edu.uci.ics.jung.algorithms.layout.util.RandomLocationTransformer<V>

Type Parameters:

V - the vertex type

All Implemented Interfaces:

com.google.common.base.Function<V,Point2D>

public class RandomLocationTransformer<V>
extends Object
implements com.google.common.base.Function<V,Point2D>

Provides a random vertex location within the bounds of the Dimension property. This provides a random location for unmapped vertices the first time they are accessed.

Note: the generated values are not cached, so apply() will generate a new random location for the passed vertex every time it is called. If you want a consistent value, wrap this layout's generated values in a StaticLayout instance.
