RandomLocationTransformer (JunGrapht Visualization 1.1 API)

java.lang.Object
- org.jungrapht.visualization.layout.util.RandomLocationTransformer<V>

Type Parameters:

V - the vertex type

All Implemented Interfaces:

Function<V,Point>
```
public class RandomLocationTransformer<V>
extends Object
implements Function<V,Point>
```
Provides a random vertex location within the bounds of the width and height. This provides a random location for unmapped vertices the first time they are accessed.
Note: the generated values are not cached, so animate() 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 instance.
