Subject [jira] [Commented] (LUCENE-4230) When pulling DocsAndPositionsEnum you should state whether you need payloads
Date Tue, 17 Jul 2012 16:25:33 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4230?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13416337#comment-13416337
] 

Michael McCandless commented on LUCENE-4230:
--------------------------------------------

bq. Can we just have a final method: d&pEnum(LiveDocs, Reuse) that calls d&pEnum(LiveDocs,
Reuse, 0) ?

bq. Also I think the flags belong on DocsAndPositionsEnum, not TermsEnum.
