SplDoublyLinkedList::setIteratorMode — Sets the mode of iteration

void SplDoublyLinkedList::setIteratorMode ( int $mode )

mode

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

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

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

No value is returned.
