25 * ElementSorted is a mixin interface for Collections that
|
|
|
26 * are always in sorted order with respect to a Comparator
|
|
|
27 * held by the Collection.
|
|
|
28 * <P>
|
|
|
29 * ElementSorted Collections guarantee that enumerations
|
|
|
30 * appear in sorted order; that is if a and b are two Elements
|
|
|
31 * obtained in succession from elements().nextElement(), that
|
|
|
32 * <PRE>
|
|
|
33 * comparator().compare(a, b) <= 0.
