Subject [jira] Commented: (LUCENE-1794) implement reusableTokenStream for all contrib analyzers
Date Sun, 16 Aug 2009 00:25:14 GMT

Yonik Seeley commented on LUCENE-1794:
--------------------------------------

bq. But even before this I think we should make sure everyone is happy with ReusingAnalyzer
itself... this is the only reason I think it might merit another issue

+1

The ReusingAnalyzer brings up other issues of protocol - right now consumers like lucene indexing
call reset() on the stream, but I see the prototype ReusingAnalyzer also calling reset() on
the stream.

> 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.
