Class VectorSet<E>

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<E>, java.util.Collection<E>, java.util.List<E>, java.util.RandomAccess

    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.
