All Implemented Interfaces:

Direct Known Subclasses:

VersionedAssetItemIterator

public class AssetItemIterator
extends Object
implements Iterator<AssetItem>

This iterates over nodes and produces RuleItem's. Also allows "skipping" of results to jump to certain items, as per JCRs "skip". JCR iterators are/can be lazy, so this makes the most of it for large numbers of assets.
