All Implemented Interfaces:: BidirectionalTransformer, MutableTransformer, ShapeTransformer, ChangeEventSupport

Direct Known Subclasses:: LensTransformer

public abstract class MutableTransformerDecorator extends Object implements MutableTransformer

a complete decorator that wraps a MutableTransformer. Subclasses use this to allow them to only declare methods they need to change.
