public abstract class UnmodifiableIterator
extends java.lang.Object
implements java.util.Iterator

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.
