Benson Margulies commented on LANG-591:
---------------------------------------
Hen,
There's a thread-safety issue here. The choices are:
1) an API that takes the strings in and returns a new results object. I object
to this on performance grounds.
2) a separate Levenshtein object that takes two strings and then returns all
the various results via get accessors (no result object).
3) an API like the one I put in the patch.
I think that #2 is the best choice, but I'd like to be on the same page as you
before I diddle further.
