  • All Implemented Interfaces:
    java.util.Enumeration<T>
    public class Enumerator<T>
extends java.lang.Object
implements java.util.Enumeration<T>

    Adapter that wraps an Enumeration around a Java 2 collection Iterator.

    Constructors are provided to easily create such wrappers.

    This class is based on code in Apache Tomcat.
