From: Rafal Krypa Date: Thu, 23 Jun 2016 09:24:59 +0000 (+0200) Subject: Remove DPL String class and dependencies on it X-Git-Tag: accepted/tizen/common/20160627.191623~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F92%2F76292%2F1;p=platform%2Fcore%2Fsecurity%2Fsecurity-manager.git Remove DPL String class and dependencies on it Security-manager doesn't use DPL String, it was taken in as requirement of DPL SQLConnection. The DPL String class introduces needless dependency on libicu. Since our code doesn't operate on UTF-8 strings and doesn't really need libicu, it's better to drop DPL String altogether.
