Deep cloning.

Wish all good things in life were so easily cloneable...

public Object clone() throws CloneNotSupportedException {
   try{
       ByteArrayOutputStream baos = new ByteArrayOutputStream();
       ObjectOutputStream oos = new ObjectOutputStream(baos);
       oos.writeObject(this);
       ByteArrayInputStream bais = 
            new ByteArrayInputStream(baos.toByteArray());
       ObjectInputStream ois = new ObjectInputStream(bais);
       Object deepCopy = ois.readObject();
   }
   catch(Exception e){
       throw CloneNotSupportedException(e);
   }
  return deepCopy;
}
