Class NodeListCache

java.lang.Object
  org.mmbase.cache.Cache<SearchQuery,List<MMObjectNode>>
      org.mmbase.cache.QueryResultCache
          org.mmbase.cache.NodeListCache

All Implemented Interfaces:

Map<SearchQuery,List<MMObjectNode>>, CacheMBean, EventListener, NodeEventListener, RelationEventListener, SizeMeasurable

public class NodeListCache
extends QueryResultCache

Query result cache used for getNodes from MMObjectBuilder. So it contains only simple nodes (no clusternodes). The query can contain more than one Step, the queried fields are, however, excactly all fields of one of the steps (the 'node step').
