public abstract class AbstractMapDecorator extends Object implements Map
Methods are forwarded directly to the decorated map.
This implementation does not perform any special processing with entrySet, keySet or values. 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.
