A method for modifying dynamically classes in the object-oriented dynamic programming environment

In the object-oriented dynamic programming environment, dynamic modification of a class, which permits change of it at run-time and without recompilation, is the key point to exploit flexibility and support rapid prototyping. However, it causes a problem that the existing objects of the modified class are difficult to handle. In this paper, the concept of ‘cloned class’ is introduced, and a method based on it for modifying dynamically classes is proposed.
