( int $mode
)
参数

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
