Ville Skyttä updated LANG-715:
------------------------------
Attachment: squeeze-speedup.patch
CharSetUtils.squeeze() speedup
> CharSetUtils.squeeze() speedup
> ------------------------------
>
> Key: LANG-715
> URL: https://issues.apache.org/jira/browse/LANG-715
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.*
> Affects Versions: 3.0
> Reporter: Ville Skyttä
> Priority: Minor
> Labels: patch
> Attachments: squeeze-speedup.patch
>
>
> The attached patch speeds up CharSetUtils.squeeze() by avoiding unnecessary
> calls to CharSet.contains(). It should not slow down any cases, and in my
> tests with some use cases that I consider fairly common ones I got up to
> sixfold speedups with the patch.
> It's not that squeeze() would be that slow in the first place before the
> patch; I just happened to be playing around with caliper
> (http://code.google.com/p/caliper/) and squeeze() was one of the first things
> I tried it with.
