SplQueue::setIteratorMode — Sets the mode of iteration

void SplQueue::setIteratorMode ( int $mode )

mode

There is only one iteration parameter you can modify.

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 0x0 : SplDoublyLnkedList::IT_MODE_FIFO | SplDoublyLnkedList::IT_MODE_KEEP

Warning

The direction of iteration can no longer be changer for SplQueues. Trying to do so will result in a RuntimeException being thrown.
