Subject [jira] Updated: (LUCENENET-11) Avoiding non necessary exceptions
Date Thu, 26 Oct 2006 20:10:19 GMT
     [ http://issues.apache.org/jira/browse/LUCENENET-11?page=all ]

Joe Shaw updated LUCENENET-11:
------------------------------

    Attachment: 11_charstream-no-exceptions.patch

I just noticed that we've had a similar patch in our tree (for Beagle) for quite some time
and have been using it for over a year.  It only addresses the FastCharStream in the StandardAnalyzer,
but it should be easy to apply it to the QueryParser as well.

> As already said in previous issues, there are few exceptions that are raised for  no
reason (apparently).
> I updated  FastCharStream, QueryParserTokenManager, FieldInfos to avoid these kind of
exception.
> - FastCharStream.ReadChar() returns '\0' if we are trying to read byond the end of the
stream.
> - Updated QueryParserTokenManager to support the previous fix
> - Update FieldInfos.FieldName. No more reading take place if fieldNumber is -1.
