Class ArrayHits

java.lang.Object

org.apache.jackrabbit.core.query.lucene.hits.ArrayHits

All Implemented Interfaces:

Hits

public class ArrayHits
extends Object
implements Hits

Uses an integer array to store the hit set. This implementation uses less memory than BitSetHits if the total number of documents is high and and the number of hits is low or if your hits doc numbers are mostly in the upper part of your doc number range. If you don't know about your hit distribution in advance use AdaptingHits instead.
