The default mode is: SplDoublyLinkedList::IT_MODE_FIFO | SplDoublyLinkedList::IT_MODE_KEEP

Warnung

The direction of iteration can not be changed for SplStack and SplQueue classes, it is always SplDoublyLinkedList::IT_MODE_FIFO. Trying to modify it will result in a RuntimeException being thrown.

Rückgabewerte

Returns the different modes and flags that affect the iteration.
