XZ for Java =========== Introduction This aims to be a complete implementation of XZ data compression in pure Java. Features: - Full support for the .xz file format specification version 1.0.4 - Single-threaded streamed compression and decompression - Single-threaded decompression with limited random access support - Raw streams (no .xz headers) for advanced users, including LZMA2 with preset dictionary Threading is planned but it is unknown when it will be implemented. For the latest source code, see the project home page: http://tukaani.org/xz/java.html The source code is compatible with Java 1.4 and later. Building It is recommended to use Apache Ant. Type "ant" to compile the classes and create the .jar files. Type "ant doc" to build the javadoc HTML documentation. Note that building the documentation will download a small file named "package-list" from Oracle to enable linking to the documentation of the standard Java classes. If you cannot or don't want to use Ant, just compile all .java files under the "src" directory. Demo programs You can test compression with XZEncDemo, which compresses from standard input to standard output: java -jar build/jar/XZEncDemo.jar < foo.txt > foo.txt.xz You can test decompression with XZDecDemo, which decompresses to standard output: java -jar build/jar/XZDecDemo.jar foo.txt.xz Reporting bugs Report bugs to <email@example.com> or visit the IRC channel #tukaani on Freenode and talk to Larhzu.
