Subject [jira] Commented: (LANG-591) A more complex Levenshtein distance would be useful
Date Mon, 08 Feb 2010 02:45:27 GMT


Henri Yandell commented on LANG-591:

Not a fan of the API - i.e. LevenshteinResults should be an immutable return, not a mutable
passed in. setXxx methods should be removed.

I'd also be tempted to retcon the old API on top of the new one - slows it down a bit, though
a private method with a boolean 'collateResults' parameter could be used to keep things largely

> For some applications, it is necessary to get insert/delete/substitution counts from
the distance algorithm. I am attaching a patch that provides this.
