Examples of GzipReader

org.jwat.gzip.GzipReader
A reader for (multi-part) GZip files. Validates header and CRC's. Entries are read sequentially from the input stream. Random access is supported indirectly if the used input stream supports this. Compressed data is available through an uncompressing input stream wrapper. @author nicl
