15 * This iterator just overrides the rewind method in order to correct a PHP bug,
16 * which existed before version 5.5.23/5.6.7.
18 * @see https://bugs.php.net/68557
20 * @author Alex Bogomazov
22 * @deprecated since 3.4, to be removed in 4.0.
24 abstract class FilterIterator extends \FilterIterator
27 * This is a workaround for the problem with \FilterIterator leaving inner \FilesystemIterator in wrong state after
28 * rewind in some cases.
30 * @see FilterIterator::rewind()
