Example 6 with CBZip2OutputStream

use of org.apache.tools.bzip2.CBZip2OutputStream in project SilverKing by Morgan-Stanley.

the class BZip2 method compress.

public byte[] compress(byte[] rawValue, int offset, int length) throws IOException {
    ByteArrayOutputStream baos;
    CBZip2OutputStream bzip2os;
    byte[] buf;
    int compressedLength;
    // Log.warning("rawValue.length ", rawValue.length);
    baos = new ByteArrayOutputStream(rawValue.length / bzip2InitFactor);
    baos.write(0x42);
    baos.write(0x5a);
    bzip2os = new CBZip2OutputStream(baos);
    bzip2os.write(rawValue, offset, length);
    bzip2os.flush();
    bzip2os.close();
    baos.flush();
    baos.close();
    buf = baos.toByteArray();
    // System.out.println(StringUtil.byteArrayToHexString(buf));
    compressedLength = buf.length;
    if (Log.levelMet(Level.FINE)) {
        Log.fine("rawValue.length: " + rawValue.length);
        Log.fine("buf.length: " + buf.length);
        Log.fine("compressedLength: " + compressedLength);
    }
    // System.out.println("\t"+ StringUtil.byteArrayToHexString(buf));
