Provides a base decorator that enables additional functionality to be added
to a Map via decoration.
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.
