Subject [jira] Commented: (LUCENE-1849) Add OutOfOrderCollector and InOrderCollector subclasses of Collector
Date Mon, 24 Aug 2009 20:26:59 GMT


Tim Smith commented on LUCENE-1849:

i was just proposing AbstractCollector to consolidate the "variations" of abstract subclasses
of Collector

I like ScoringCollector
i would also like a NonScoringCollector

in this case, i would recommend both should take the "allowDocsOutOfOrder" flag in their constructors
(and store in a private final returned by acceptingOutOfOrderDocs())
otherwise, i would still want to see 2 variations on each of ScoringCollector and NonScoringCollector
to handle the OutOfOrder vs InOrder variations

> I find myself always having to implement these methods, and i always return a constant
(depending on if the collector can handle out of order hits)
> would be nice for these two convenience abstract classes to exist that implemented acceptsDocsOutOfOrder()
as final and returned the appropriate value
