org.biojava3.core.util.UncompressInputStream
- All Implemented Interfaces:
- Closeable
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.
