public abstract class AbstractObjectIterator
extends Object
implements ObjectIterator

An abstract class facilitating the creation of type-specific iterators.

To create a type-specific iterator you need both a method returning the next element as primitive type and a method returning the next element as an object. However, if you inherit from this class you need just one (anyone). Moreover, remove() will throw an UnsupportedOperationException.

This class implements also a trivial version of skip().
