org.biojava.nbio.core.util.UncompressInputStream

All Implemented Interfaces:: Closeable, AutoCloseable

public class UncompressInputStream extends FilterInputStream

This class decompresses an input stream containing data compressed with the unix "compress" utility (LZC, a LZW variant). This code is based heavily on the unlzw.c code in gzip-1.2.4 (written by Peter Jannesen) and the original compress code. This version has been modified from the original 0.3-3 version by the Unidata Program Center (support@xxxxxxxxxxxxxxxx) to make the constructor public and to fix a couple of bugs. Also: - markSupported() returns false - add uncompress() static method

Version:: 0.3-3 06/05/2001
Author:: Ronald Tschalar, Unidata Program Center, Richard Holland - making LZW_MAGIC package-visible.
