java.lang.Object
- edu.uci.ics.jung.visualization.transform.MutableTransformerDecorator

All Implemented Interfaces:

BidirectionalTransformer, MutableTransformer, ShapeTransformer, ChangeEventSupport

Direct Known Subclasses:

LensTransformer
```
public abstract class MutableTransformerDecorator
extends java.lang.Object
implements MutableTransformer
```
a complete decorator that wraps a MutableTransformer. Subclasses use this to allow them to only declare methods they need to change.
