Chris Male updated LUCENE-3396:
-------------------------------
Attachment: LUCENE-3396-remaining-merging.patch
Patch which finalizes the remaining Analyzer changes and merges
ReusableAnalyzerBase and Analyzer together.
Command for the patch:
{code}
# Keep old Analyzer.java temporarily for comparison
svn rename lucene/src/java/org/apache/lucene/analysis/Analyzer.java
lucene/src/java/org/apache/lucene/analysis/Analyzer.java.old
svn rename lucene/src/java/org/apache/lucene/analysis/ReusableAnalyzerBase.java
lucene/src/java/org/apache/lucene/analysis/Analyzer.java
{code}
I have updated the javadocs to reflect the merging and have removed the
assertFinal() assertion since tokenStream() and reusableTokenStream() are
always final now.
All tests pass and javadocs build. I am looking to commit this soon (with a
MIGRATE.txt entry).

> 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).
