Examples of java.util.zip.InflaterInputStream

java.util.zip.InflaterInputStream
This class implements a stream filter for uncompressing data in the "deflate" compression format. It is also used as the basis for other decompression filters, such as GZIPInputStream. @see Inflater @version 1.40, 04/07/06 @author David Connelly
