public abstract class ResponseWriterWrapper

extends ResponseWriter

Provides a simple implementation of ResponseWriter that can be subclassed by developers wishing to provide specialized behavior to an existing ResponseWriter instance. The default implementation of all methods is to call through to the wrapped ResponseWriter.

Usage: extend this class and override getWrapped() to return the instance we are wrapping.
