Description
This is the streambuf class used by DeflatingInputStream and DeflatingOutputStream. The actual work is delegated to zlib 1.2.1 (see http://www.gzip.org). Both zlib (deflate) streams and gzip streams are supported. Output streams should always call close() to ensure proper completion of compression. A compression level (0 to 9) can be specified in the constructor.
