Class UnmodifiableIterator<E>

public abstract class UnmodifiableIterator<E> extends Object implements Iterator<E>

UnmodifiableIterator is an abstract superclass to save you the trouble of implementing the remove() method over and over again for those iterators which don't implement it. The name's a bit clunky, but fits with the JDK naming in java.util.Collections and etc.
