Class QueryBox

java.lang.Object

org.infinispan.query.clustered.QueryBox

public class QueryBox
extends Object

Each node in the cluster has a QueryBox instance. The QueryBox keep the active lazy iterators (actually it keeps the DocumentExtractor of the searches) on the cluster, so it can return values for the queries in a "lazy" way. When a DistributedLazyIterator is created, every nodes creates a DocumentExtractor and register it in your own QueryBox. So, the LazyIterator can fetch the values in a lazy way. EVICTION: Currently the QueryBox keeps the last BOX_LIMIT DocumentExtractor used... probably there is a better way.
