public abstract class LookAheadIterator<E>
extends LookAheadIteration<E,RuntimeException>
implements CloseableIterator<E>

An iterator that looks one element ahead, if necessary, to handle calls to LookAheadIteration.hasNext(). This is a convenient super class for iterators that have no easy way to tell if there are any more results, but still should implement the java.util.Iterator interface.
