Chris Male updated LUCENE-3396:
-------------------------------
Attachment: LUCENE-3396-rab.patch
This is the uber patch which converts all but 8 Analyzers over to using
ReusableAnalyzerBase.
This also introduces the ReuseStrategy concept to ReusableAnalyzerBase (will
need some documentation before committing). For simplicity, the ReuseStrategy
maintains its own CloseableThreadLocal.
The remaining Analyzers can be converted when I push the ReuseAnalyzerBase
logic into Analyzer.
After some small tidy (and a review) I think we should commit this even though
we're going to collapse ReusabeAnalyzerBase.
> Make TokenStream Reuse Mandatory for Analyzers

> In LUCENE-2309 it became clear that we'd benefit a lot from Analyzer having
> to return reusable TokenStreams. This is a big chunk of work, but its time
> to bite the bullet.
> I plan to attack this in the following way:
> - Collapse the logic of ReusableAnalyzerBase into Analyzer
> - Add a ReuseStrategy abstraction to Analyzer which controls whether the
> TokenStreamComponents are reused globally (as they are today) or per-field.
> - Convert all Analyzers over to using TokenStreamComponents. I've already
> seen that some of the TokenStreams created in tests need some work to be
> reusable (even if they aren't reused).
> - Remove Analyzer.reusableTokenStream and convert everything over to using
> .tokenStream (which will now be returning reusable TokenStreams).
