Org.simantics.fastlz

org.simantics.fastlz is a simple JNI wrapper for the open-source FastLZ real-time data compression library. The native library is a pure C implementation. Our version is based on SVN revision 12.

Dependencies

• None, it is a self-sufficient JAR ready for deployment
• Data to compress/decompress!

Manual

All use of the FastLZ java library happens through the org.simantics.fastlz.FastLZ facade class:

    public static native int compress(ByteBuffer input, int inputOffset, int length,
                                      ByteBuffer output, int outputOffset);

    public static native int decompress(ByteBuffer input, int inputOffset, int length, 
                                        ByteBuffer output, int outputOffset, int maxout);

    public static InputStream read(File file) throws FileNotFoundException;

    public static OutputStream write(File file) throws FileNotFoundException;

All ByteBuffers used in this interface are assumed to be direct byte buffers (see ByteBuffer.allocateDirect).
