Subject [jira] [Commented] (LUCENE-3084) MergePolicy.OneMerge.segments should be List<SegmentInfo> not SegmentInfos
Date Thu, 12 May 2011 07:41:47 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13032291#comment-13032291

Simon Willnauer commented on LUCENE-3084:
-----------------------------------------

bq. NavigableSet ist Java 6. SortedSet only works if the set ordering is defined by its contents
fair enough. I still think we can make it SortedSet as we know the ordering otherwise we could
not build the list right?

for now I think we should implement Iterable<SI> and offer a method List<SI> asList()
to make it consistent with FIS and Document (conclusion from the discussion with uwe on IRC).

Eventually I would prefer having a set here really.

> SegmentInfos carries a bunch of fields beyond the list of SI, but for merging purposes
these fields are unused.
> We should cutover to List<SI> instead.
