java.util.zip.DeflaterOutputStream
This class implements an output stream filter for compressing data in the "deflate" compression format. It is also used as the basis for other types of compression filters, such as GZIPOutputStream. @see Deflater @version 1.36, 03/13/06 @author David Connelly
net.zschech.gwt.comet.server.deflate.DeflaterOutputStream

This class implements a stream which compresses data into the zlib format (RFC 1950).

The compression level can be specified, as a symbolic value identical to what the Deflater class expects. The default compression level is MEDIUM.
