org.apache.jackrabbit.vault.fs.api.FilterSet<E>

All Implemented Interfaces:

Dumpable

Direct Known Subclasses:

ItemFilterSet, PathFilterSet

public abstract class FilterSet<E extends Filter>
extends java.lang.Object
implements Dumpable

The item filter set holds a set of item filters each attributed 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.
