public abstract class AbstractSortedMapDecorator extends AbstractMapDecorator implements SortedMap
Methods are forwarded directly to the decorated map.
This implementation does not perform any special processing with the map views. Instead it simply returns the set/collection from the wrapped map. This may be undesirable, for example if you are trying to write a validating implementation it would provide a loophole around the validation. But, you might want that loophole, so this class is kept simple.
