The IteratorIterator class

Einführung

This iterator wrapper allows the conversion of anything that is Traversable into an Iterator. It is important to understand that most classes that do not implement Iterators have reasons as most likely they do not allow the full Iterator feature set. If so, techniques should be provided to prevent misuse, otherwise expect exceptions or fatal errors.
