-/**
- * @brief   Cached iteration over another Iterator
- * @author  Marcus Boerger
- * @version 1.2
- * @since PHP 5.0
- *
- * This iterator wrapper does a one ahead iteration. This way it knows whether
- * the inner iterator has one more element.
- *
- * @note If you want to convert the elements into strings and the inner 
- *       Iterator is an internal Iterator then you need to provide the 
- *       flag CALL_TOSTRING to do the conversion when the actual element
- *       is being fetched. Otherwise the conversion would happen with the
- *       already changed iterator. If you do not need this then it you should
- *       omit this flag because it costs unneccessary work and time.
