so i could use the clone() method and instead of saying

 // set leftChild
   public void setLeftChild(GridNode newLeftChild)
   {
      leftChild = newLeftChild;
   } // end setLeftChild

i would say something like this (and i havent compile or tried this, i dont have time right now but i just want to get the idea)

(Toggle Plain Text)

 // set leftChild
   public void setLeftChild(GridNode newLeftChild)
   {
      leftChild = (GridNode) newLeftChild.clone();
   } // end setLeftChild

and that will make a seperate exact deep copy, correct? And then whatever i wanted to change in the copy i could and it will only change that one because it is not just a pointer to it, correct?
