jbzip2

This repository was exported from the jbzip2 Google Code project to ensure it survives the service’s shutdown. We are not the library’s authors; expect no updates here.

The original description of the Google Code project follows.


jbzip2 is a Java bzip2 compression/decompression library. It can be used as a replacement for the Apache CBZip2InputStream / CBZip2OutputStream classes

News

  • 13/10/2011 jbzip2-0.9.1 is now available. This release fixes numerous bugs in both compression and decompression.
  • 25/05/2011 jbzip2-0.9 is now available

Features

  • A decompressor that is typically 5% to 10% faster than CBZip2InputStream
  • A compressor of broadly comparable speed to CBZip2OutputStream (slightly slower in some cases, rather faster than others)
  • Legible, well factored code suitable for studying how the algorithms of BZip2 work

Usage

Testers Wanted

  • jbzip2 has been tested successfully on a moderately large and diverse body of data, but more is needed. Please help by testing jbzip2 on your own data

  • Testing can be carried out using the RoundTrip utility included in the distribution:

    java -cp jbzip2-0.9.1.jar demo.RoundTrip /path/to/test/data
  • Each ordinary readable file beneath the given path will be compressed into a temporary file, then decompressed (no files will be created or altered in place). If any error is encountered, the test will stop with an exception

  • Reports of success, as well as failure would be most welcome. Feedback can be sent to the author
