public class ItemFilterSet
extends FilterSet<ItemFilter>

The item filter set holds a set of item filters each attributes as include or exclude filter. The evaluation of the set allows included items and rejects excluded items.

Additionally it contains a "root" path for which the filters are evaluated. if an item has not the node addressed by the root path as ancestor, it is always excluded.
