org.apache.catalina.util.Enumerator
Adapter class that wraps an Enumeration around a Java2 collection classes object Iterator so that existing APIs returning Enumerations can easily run on top of the new collections. Constructors are provided to easliy create such wrappers. @author Craig R. McClanahan @version $Revision: 466595 $ $Date: 2006-10-21 23:24:41 +0100 (Sat, 21 Oct 2006) $
