public class TransformedSortedBag extends TransformedBag implements SortedBag
SortedBag
to transform objects that are added.
The add methods are affected by this class. Thus objects must be removed or searched for using their transformed form. For example, if the transformation converts Strings to Integers, you must use the Integer form to remove objects.
