note 106841 added to spldoublylinkedlist.getiteratormode

I think it should be noted that the IT_MODE_* constants are defined inside the class as: IT_MODE_LIFO => int(2) IT_MODE_FIFO => int(0) IT_MODE_DELETE => int(1) IT_MODE_KEEP => int(0) With the FIFO and KEEP flags both defined as zero, you can run into an ambiguity when trying to discern what modes have been activated when trying to use bitwise deduction as one might be lead to believe considering the bitwise way you set the iterator mode (at least in v5.3.5, haven't tested any others). Consider this example: <?php $l = new SPLDoublyLinkedList(); $l->setIteratorMode(SplDoublyLinkedList::IT_MODE_FIFO | SplDoublyLinkedList::IT_MODE_DELETE); $mode = $l->getIteratorMode(); #int(1) var_dump(($mode & SplDoublyLinkedList::IT_MODE_FIFO) == SplDoublyLinkedList::IT_MODE_FIFO); #outputs true var_dump(($mode & SplDoublyLinkedList::IT_MODE_LIFO) == SplDoublyLinkedList::IT_MODE_LIFO); #outputs false var_dump(($mode & SplDoublyLinkedList::IT_MODE_DELETE) == SplDoublyLinkedList::IT_MODE_DELETE); #outputs true var_dump(($mode & SplDoublyLinkedList::IT_MODE_KEEP) == SplDoublyLinkedList::IT_MODE_KEEP); #outputs true (huh?!) ?> Regardless of whatever the getIteratorMode tells you, the object DOES correctly honor the configuration that was set as far as I can tell.
