Alan Woodward resolved LUCENE-6228. ----------------------------------- Resolution: Fixed Assignee: Alan Woodward (was: Adrien Grand) Fix Version/s: (was: 6.0) (was: 5.2) master (8.0) I changed FilterScorable accordingly. Thanks for the reviews! > Do not expose full-fledged scorers in LeafCollector.setScorer > ------------------------------------------------------------- > > Key: LUCENE-6228 > URL: https://issues.apache.org/jira/browse/LUCENE-6228 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Adrien Grand > Assignee: Alan Woodward > Priority: Major > Fix For: master (8.0) > > Attachments: LUCENE-6228.patch, LUCENE-6228.patch, LUCENE-6228.patch, > LUCENE-6228.patch, LUCENE-6228.patch, LUCENE-6228.patch > > > Currently LeafCollector.setScorer takes a Scorer, which I don't like because > several methods should never be called in the context of a Collector (like > nextDoc or advance). > I think it's even more trappy for methods that might seem to work in some > particular cases but will not work in the general case, like getChildren > which will not work if you have a specialized BulkScorer or iterating over > positions which will not work if you are in a MultiCollector and another leaf > collector consumes positions too. > So I think we should restrict what can be seen from a collector to avoid such > traps. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
