public final class VectorSet
extends java.util.Vector

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.

Since:

Ant 1.8.0
