public final class VectorSet<E>
extends java.util.Vector<E>
Subclass of Vector that won't store duplicate entries and shows
HashSet's constant time performance characteristics for the
contains method.
This is not a general purpose class but has been written because
the protected members of DirectoryScanner prohibited
later revisions from using a more efficient collection.
Methods are synchronized to keep Vector's contract.
