Java IO: FilterWriter

Last update: 2014-06-23

The FilterWriter is a base class for implementing your own filtering Writer's. Basically it just overrides all methods in Writer.

Like with FilterOutputStream, I see no sensible purpose for this class. I cannot see that this class actually adds or changes any behaviour in Writer except that it takes a Writer in its constructor. If you choose to extend this class you might as well extend the Writer class directly, and avoid the extra class in the hierarchy.
