Because I wanted to use the javaCC input code from Lucene. 99.99% of
what the standard parser did was VERY GOOD. having worked with
computer-generated compilers in the past, I realized that if I were to
modify the parser itself, I would eventually get into real trouble. So
I took the time to figure out how to use JavaCC, with a great deal of
help from Mr. Miller. Now I can make changes much more easily.
That is why I took the trouble to do it that way.

Your problem is that StandardTokenizer doesn's fit your requirements.
Since you know how to implement a new one, just do it.
If you just want to modify StandardTokenizer, you can get the codes and
rename it to your class, then modify something that you dislike. I
think
it's a so simple stuff, why do you make it so complicated?

If I use the generated parse exception, I get the message that the
ParseException which is thrown by next() is incompatible with the
throws statement in the generated code. If I get rid of it and use
the
older one, it turns out that generateException cannot generate a
ParseException because it passes a generated Token instead of the
Lucene Token.
It appears that the JavaCC I am using is generating code which is a
bit
ahead of Lucene.
So I simply generated a new token of hte roper Lucene type for the
error message and everything compiled. Now I have to tell the query
parser to use the same analyzer and all will be well.
Thanks.
The good news is that Lucene is unbelievably wonderful. The bad news
is that Lucene is unbelievably wonderful.
Thanks again.
