| NodeFilter | NodeFilter is used to update nodes and complete children of nodes while applying queries on the fly and keeping track of any child changes. |
| NodeFilter.CompleteChildSource | Since updates to filtered nodes might require nodes to be pulled in from "outside" the node, this interface can help to get complete children that can be pulled in. |
| ChildChangeAccumulator | |
| IndexedFilter | Doesn't really filter nodes but applies an index to the node and keeps track of any changes |
| LimitedFilter | Applies a limit and a range to a node and uses RangedFilter to do the heavy lifting where possible |
| RangedFilter | Filters nodes by range and uses an IndexFilter to track any changes after filtering the node |
