public abstract class AbstractCompressedStream
extends ServletOutputStream

Skeletal implementation of a CompressedStream. This class adds compression features to a ServletOutputStream and takes care of setting response headers, etc. Major work and configuration is done here. Subclasses using different kinds of compression only have to implement the abstract methods doCompress() and setContentEncoding() using the desired compression and setting the appropriate Content-Encoding header string.
