Michael McCandless commented on LUCENE-1679:
--------------------------------------------
I like the cleanup patch, but, I think we should not remove close()? Even
though it's basically a no-op, removing it breaks back-compat.
Technically, changing the members to final is also a break to back-compat, but
I think it's acceptable because WildcardTermEnum basically requires that these
are final (ie, you can't up and change say "pre" after creation, because the
enum has already been set).
> Make WildcardTermEnum#difference() non-final

> Key: LUCENE-1679
> URL: https://issues.apache.org/jira/browse/LUCENE-1679
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Search
> Affects Versions: 2.9
> Reporter: Simon Willnauer
> Assignee: Michael McCandless
> Priority: Minor
> Fix For: 2.9
>
> 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
