Subject [jira] Created: (LUCENE-1679) Make WildcardTermEnum#difference() non-final
Date Wed, 10 Jun 2009 08:11:07 GMT
Make WildcardTermEnum#difference() non-final

                 Key: LUCENE-1679
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Search
    Affects Versions: 2.9
            Reporter: Simon Willnauer
            Priority: Minor
         Attachments: WildcardTermEnum.patch, WildcardTermEnum_cleanup.patch

The method WildcardTermEnum#difference() is declared final. I found it very useful to subclass
WildcardTermEnum to implement different scoring for exact vs. partial matches. The change
is rather trivial (attached)  but I guess it could make life easier for a couple of users.

I attached two patches:
 - one which contains the single change to make difference() non-final (WildcardTermEnum.patch)
 - one which does also contain some minor cleanup of WildcardTermEnum. I removed unnecessary
member initialization and made those final. ( WildcardTermEnum_cleanup.patch)

Thanks simon
