- * Keyed is an interface most useful in association with SortedCollections.
- * Any class implementing Keyed contains method key, that returns
- * an object serving as a sorting key for the rest of the object.
- * <P>
- * The DefaultComparator class checks to see if its arguments
- * are Keyed, and if so uses the keys as the basis for comparison.
