Stanislaw Osinski updated LUCENE-966:
-------------------------------------

    Attachment: jflex-analyzer-patch.txt

Here comes a somewhat rough (needing refactorings, see below) patch adding a JFlex-based repalcement for StandardAnalyzer called FastAnalyzer.  A few comments:

* all tests from TestStandardAnalyzer pass
* tokenizer generation added to Ant build scripts

Because FastAnalyzer shares some code with StandardAnalyzer, it might be worthwhile to do some refactorings:

* have a common test for both analyzers (only if we want to keep them in sync)
* have a common superclass for FastFilter and StandardFilter
* have a common superclass for FastAnalyzer and StandardAnalyzer

> JFlex (http://www.jflex.de/) can be used to generate a faster (up to several times) replacement for StandardAnalyzer. Will add a patch and a simple benchmark code in a while.
