Examples of java.util.zip.DeflaterOutputStream

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
