Method Details

collect

public void collect(int doc)
             throws IOException

Description copied from interface: LeafCollector

Called once for every document matching a query, with the unbased document number.

Note: The collection of the current segment can be terminated by throwing a CollectionTerminatedException. In this case, the last docs of the current LeafReaderContext will be skipped and IndexSearcher will swallow the exception and continue collection with the next leaf.

Note: This is called in an inner search loop. For good search performance, implementations of this method should not call StoredFields.document(int) on every hit. Doing so can slow searches by an order of magnitude or more.

Specified by:

collect in interface LeafCollector

Specified by:

collect in class SimpleCollector

Throws:

IOException

process

private void process(int groupOrd,
 int facetOrd)
              throws IOException

Throws:

IOException

doSetNextReader

protected void doSetNextReader(LeafReaderContext context)
                        throws IOException

Description copied from class: SimpleCollector

This method is called before collecting context.

Overrides:

doSetNextReader in class SimpleCollector

Throws:

IOException

createSegmentResult

protected TermGroupFacetCollector.MV.SegmentResult createSegmentResult()
                                                                throws IOException

Specified by:

createSegmentResult in class GroupFacetCollector

Throws:

IOException
