Subject [jira] Commented: (LUCENE-1794) implement reusableTokenStream for all contrib analyzers
Date Thu, 13 Aug 2009 21:23:14 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1794?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12742978#action_12742978

Shai Erera commented on LUCENE-1794:
------------------------------------

Also Robert, I've looked at the patch and I see that you don't call reset() on streams.result,
just on source. I think you should call that on streams.result too. You do it in TestSynonymTokenFilter.

If we go w/ my proposal above, such issues will not happen, since there will be only one copy
of reusableTokenStreams (at least for the majority of analyzers).

> most contrib analyzers do not have an impl for reusableTokenStream
> regardless of how expensive the back compat reflection is for indexing speed, I think
we should do this to mitigate any performance costs. hey, overall it might even be an improvement!
> the back compat code for non-final analyzers is already in place so this is easy money
in my opinion.
