Subject [jira] Commented: (LUCENE-2265) improve automaton performance by running on byte[]
Date Fri, 02 Apr 2010 23:27:27 GMT


Earwin Burrfoot commented on LUCENE-2265:

I probably missed something.

Why can't you create UTF-8 Automaton from the get go?

>    Affects Versions: Flex Branch
>            Reporter: Robert Muir

> Currently, when enumerating terms, automaton must convert entire terms from flex's native
utf-8 byte[] to char[] first, then step each char thru the state machine.
> we can make this more efficient, by allowing the state machine to run on byte[], so it
can return true/false faster.
