public class SingleElementListIterator<E>
extends java.lang.Object
implements IterableListIterator<E>

A SingleElementListIterator holds a single element and returns it with the first call to next(), at which point it will return false to any subsequent call to hasNext(). Likewise, it will return false to a call to hasPrevious()< until a call to next(), at which point a call to previous() will return the single element.
