@Internal
public class OneDimensionalTermHitCollector
extends AbstractOneDimensionalHitCollector

A HitCollector that creates a doc -> term mapping. This is useful for collecting documents where there are a limited number of terms. The caching also ensures that if multiple searches sort on the same terms, the doc -> term mapping is maintained.

This HitCollector can be quite memory intensive, however the cache is stored with a weak reference, so it will be garbage collected.

Method Details

collectIrrelevant

protected void collectIrrelevant(int docId)

Description copied from class: AbstractOneDimensionalHitCollector

Implement this if you would like to do something when the hit collector has encountered a docId that contains an irrelevant data match

Specified by:

collectIrrelevant in class AbstractOneDimensionalHitCollector

Parameters:

docId - the match we have found. This is an index into the overall directory reader.

getResult

public Map<String,Integer> getResult()

collectWithTerms

protected void collectWithTerms(int docId,
 JiraBytesRef[] terms)

Description copied from class: AbstractOneDimensionalHitCollector

Implement this if you would like to do something with the hit we have found.

Specified by:

collectWithTerms in class AbstractOneDimensionalHitCollector

Parameters:

docId - the doc id of the hit. This is an index into the overall directory reader.

terms - the terms for the fieldId for this document, pre-calculated so you may not need to call getDocument
