All Implemented Interfaces:

Closeable

public class BZip2InputStream
extends InputStream

This is an InputStream for reading bzip2 encoded data.

For more information on the inner workings of bzip2, see the Wikipedia article on bzip2.

This stream is not safe for concurrent access by several writing threads. A client must provide external synchronization to use this from several threads.
