There are two orthogonal sets of modes that can be set:

• The direction of the iteration (either one or the other):
  • SplDoublyLinkedList::IT_MODE_LIFO (Stack style)
  • SplDoublyLinkedList::IT_MODE_FIFO (Queue style)
• The behavior of the iterator (either one or the other):
  • SplDoublyLinkedList::IT_MODE_DELETE (Elements are deleted by the iterator)
  • SplDoublyLinkedList::IT_MODE_KEEP (Elements are traversed by the iterator)

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