[jira] [Commented] (LUCENE-4924) Make DocIdSetIterator.docID()
return -1 when not positioned
[ https://issues.apache.org/jira/browse/LUCENE-4924?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13627721#comment-13627721 ]
Yonik Seeley commented on LUCENE-4924:
--------------------------------------
Undefined can sometimes lead to more efficient implementations in certain circumstances. IIRC this was actually true of some iterators at some point in the past, but I don't know if it's still the case.

> Today DocIdSetIterator.docID() can either return -1 or NO_MORE_DOCS when the enum is not positioned. I would like to only allow it to return -1 so that we can have better assertions.
> (This proposal is for trunk only.)
