Class IteratorEnumerationBridge<E>

java.lang.Object
  org.torweg.pulse.util.IteratorEnumerationBridge<E>

Type Parameters:

E - the type of the bridged Enumeration/Iterator

All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Enumeration<E>, java.util.Iterator<E>

public final class IteratorEnumerationBridge<E>
extends java.lang.Object
implements java.util.Iterator<E>, java.util.Enumeration<E>, java.lang.Iterable<E>

a bridge between Iterator and Enumeration.

This class allows you to treat an Enumeration as an Iterator and vice versa. Moreover it can be directly used in for-each loops (enhanced for loops).
