All Implemented Interfaces:

Closeable, AutoCloseable, InputStreamStatistics

Direct Known Subclasses:

ZCompressorInputStream

public abstract class LZWInputStream
extends CompressorInputStream
implements InputStreamStatistics

Generic LZW implementation. It is used internally for the Z decompressor and the Unshrinking Zip file compression method, but may be useful for third-party projects in implementing their own LZW variations.
