From: Eunki, Hong Date: Fri, 12 May 2023 04:15:13 +0000 (+0900) Subject: Fix invalidated PipelineCacheL2 pointer problem X-Git-Tag: dali_2.2.27~3^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F32%2F292732%2F6;p=platform%2Fcore%2Fuifw%2Fdali-core.git Fix invalidated PipelineCacheL2 pointer problem Let we keep std::list::iterator instead of PipelineCacheL2*. So, the pointer of pipeline what render-renderer has should be valid even if cache container size changed. And also, for safe issue, let we keep the pipeline container as std::list.
