Subject [jira] [Updated] (LUCENE-3455) All Analysis Consumers should use reusableTokenStream
Date Sun, 25 Sep 2011 06:02:26 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-3455?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Male updated LUCENE-3455:
-------------------------------

    Attachment: LUCENE-3455-test-consumers.patch

Patch which converts all test consumers over to using reusableTokenStream.

Included is a fix for PatternAnalyzer, where I had missed re-creating the Matcher which prevented
reuse.

I'm going to commit this shortly and then attack production code.

> With Analyzer now using TokenStreamComponents, theres no reason for Analysis consumers
to use tokenStream() (it just gives bad performance).  Consequently all consumers will be
moved over to using reusableTokenStream().  The only challenge here is that reusableTokenStream
throws an IOException which many consumers are not rigged to deal with.
> Once all consumers have been moved, we can rename reusableTokenStream() back to tokenStream().
