@Override
public Object decodeFromWire(int position, Buffer buffer) {

  int _pos = position;

  // Length
  int clazzNameLength = buffer.getInt(_pos);
  String clazz = buffer.getString(_pos+=4, _pos+=clazzNameLength);

  // Jump 4 because getInt() == 4 bytes
  int dataLength = buffer.getInt(_pos+=4);

  String data = buffer.getString(_pos+=4, _pos+=dataLength);

  Object obj = null;
  try {
    obj = MAPPER.readValue(data, Class.forName(clazz));
  } catch (Exception e) {
    log.error(e.getMessage(), e);
  }

  // We can finally create custom message object
  return obj;
}
