Subject [jira] Updated: (LUCENE-2606) optimize contrib/regex for flex
Date Wed, 18 Aug 2010 12:18:16 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-2606?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Muir updated LUCENE-2606:
--------------------------------

    Attachment: LUCENE-2606.patch

attached is another iteration:
* because the Query stores RegexCapabilities, i pulled the 'matcher' stuff out so the enum
just calls matcher = capability.compile(pattern);
This way the capabilities stores no real state, only the matcher which is created in the TermsEnum.
* the RegexCapabilities is also marked serializable (LUCENE-961)

> * changes RegexCapabilities match(String) to match(BytesRef)
> * the jakarta and jdk impls uses CharacterIterator/CharSequence matching against the
utf16result instead.
> * i also reuse the matcher for jdk, i don't see why we didnt do this before but it makes
sense esp since we reuse the CSQ
