I agree with you. I found JFlex <http://www.jflex.de>, that is *much* faster than a hand-written scanner, as the benchmarks below show.
I think space is *much* more important than speed when it comes to parsing URIs. How big is the generated scanner?
I'm also skeptical as to how JFlex is faster. The only thing I can think of is that a generated parser might use fewer method calls that most hard-written parsers. But unless you show a hand-written parser next to the JFlex parser, I can't tell whether the hand-written parser is just poorly written. Of course a complicated Perl-style regular expression with backtracking will be very difficult to implement by hand, but parsing URIs shouldn't need that. -- --Per Bothner [EMAIL PROTECTED] http://www.bothner.com/per/ _______________________________________________ Classpath mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/classpath
