SplStack::setIteratorMode

(PHP 5 >= 5.3.0)

SplStack::setIteratorMode — Sets the mode of iteration

void SplStack::setIteratorMode ( int $mode )

mode

There is only one iteration parameter you can modify.

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 0x2 : SplDoublyLinkedList::IT_MODE_LIFO | SplDoublyLinkedList::IT_MODE_KEEP

Внимание

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