Usage

From source file:freenet.support.compress.Bzip2Compressor.java

@Override
public int decompress(byte[] dbuf, int i, int j, byte[] output) throws CompressionOutputSizeException {
    // Didn't work with Inflater.
    // FIXME fix sometimes to use Inflater - format issue?
    ByteArrayInputStream bais = new ByteArrayInputStream(dbuf, i, j);
    ByteArrayOutputStream baos = new ByteArrayOutputStream(output.length);
    int bytes = 0;
    try {/*  w  ww. j ava 2  s .co m*/
