public class TransformedSortedSet extends TransformedSet implements SortedSet
Decorates anotherSortedSet
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.
This class is Serializable from Commons Collections 3.1.
