org.hibernate.search.engine.DocumentExtractor
Helper class to extract EntityInfos out of the QueryHits. @author Emmanuel Bernard @author John Griffin @author Hardy Ferentschik
org.hibernate.search.query.engine.spi.DocumentExtractor
DocumentExtractor is a traverser over the full-text results (EntityInfo) This operation is as lazy as possible: - the query is executed eagerly - results are not retrieved until actually requested {@link #getFirstIndex()} and {@link #getMaxIndex()} define the boundaries available to {@link #extract(int)}. DocumentExtractor objects *must* be closed when the results are no longer traversed. See {@link #close()} @author Emmanuel Bernard

Examples of org.hibernate.search.engine.DocumentExtractor

      int max = max( first, hits );
      Session sess = (Session) this.session;


      int size = max - first + 1 < 0 ? 0 : max - first + 1;
      List<EntityInfo> infos = new ArrayList<EntityInfo>( size );
      DocumentExtractor extractor = new DocumentExtractor( searchFactoryImplementor, indexProjection );
      for (int index = first; index <= max; index++) {
        infos.add( extractor.extract( hits, index ) );
      }
      Loader loader = getLoader( sess, searchFactoryImplementor );
      List list = loader.load( infos.toArray( new EntityInfo[infos.size()] ) );
      if ( resultTransformer == null || loader instanceof ProjectionLoader) {
        //stay consistent with transformTuple which can only be executed during a projection
