Examples of org.drools.repository.AssetItemIterator

org.drools.repository.AssetItemIterator
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. @author Michael Neale
