Subject [jira] Updated: (LUCENE-2074) Use a separate JFlex generated Unicode 4 by Java 5 compatible StandardTokenizer
Date Mon, 16 Nov 2009 21:32:39 GMT

Uwe Schindler updated LUCENE-2074:
----------------------------------

    Attachment: LUCENE-2074.patch

Here the patch. It uses an interface containing the needed methods to easyliy switch between
both impl. The old one was deprecated and stays there (little modified) without any jflex
(which is no longer needed). If we want to change the syntax, we must generate  new JFlex
file and reenerate a new parser from it (using separate class name)

> The current trunk version of StandardTokenizerImpl was generated by Java 1.4 (according
to the warning). In Java 3.0 we switch to Java 1.5, so we should regenerate the file.
> After regeneration the Tokenizer behaves different for some characters. Because of that
we should only use the new TokenizerImpl when Version.LUCENE_30 is used as matchVersion.
