Class UncompressInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable

    public class UncompressInputStream
    extends java.io.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.
