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. The library also contains a Java port of the algorithm which is employed by the front-end if the native library is not available or if arguments are java heap buffers instead of native direct buffers.
Dependencies
- None, it is a self-sufficient JAR ready for deployment as OSGi bundle or POJO
- Data to compress/decompress!
Manual
All use of the FastLZ java library happens through the org.simantics.fastlz.FastLZ facade class:
public static int compressBuffer(ByteBuffer input, int inputOffset, int length,
ByteBuffer output, int outputOffset);
public static int decompressBuffer(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;
ByteBuffers used in this interface can be either heap (ByteBuffer.allocate) or direct (ByteBuffer.allocateDirect). Use the same buffer type for both arguments for best performance.
