Examples of Zlib

org.apache.mina.filter.support.Zlib
A helper class for interfacing with the JZlib library. This class acts both as a compressor and decompressor, but only as one at a time. The only flush method supported is Z_SYNC_FLUSH also known as Z_PARTIAL_FLUSH @author The Apache Directory Project (mina-dev@directory.apache.org) @version $Rev: 555855 $, $Date: 2007-07-13 12:19:00 +0900 (Fri, 13 Jul 2007) $
