Class MultiIterator<T>

java.lang.Object
  org.limewire.collection.MultiIterator<T>

All Implemented Interfaces:

Iterator<T>

Direct Known Subclasses:

MultiRRIterator

public class MultiIterator<T>
extends Object
implements Iterator<T>

Implements the Iterator interface.

    LinkedList<String> l1 = new LinkedList<String>();
    l1.add("Abby");
    l1.add("Bob");

    LinkedList<String> l2 = new LinkedList<String>();
    l2.add("Anderson");
    l2.add("Baker");

    for(MultiIterator<String> miterator = 
            new MultiIterator<String>(l1.iterator(), l2.iterator());
            miterator.hasNext();)
        System.out.println(miterator.next());

    Output:
        Abby
        Bob
        Anderson
        Baker
