Description copied from class: DrclObj

Returns a clone of this object. By default, this method creates an object of the same class and calls DrclObj.duplicate(Object) to duplicate the content of this object to the newly-created one.

This method uses getClass().newInstance() to create new instance. Hence, subclasses need to override this method only if the subclass is not declared as public or does not have explicit no-argument constructor. A subclass may override this method for performance reason.

Overrides:

clone in class DrclObj
