From 98a4da643c738a4246cc4cc4aa9c9f21ae47cff8 Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Tue, 6 Aug 2019 12:17:29 -0400 Subject: Add ApiUtils to facilitate looping over features A number of places in the code (common & drools-pdp) loop over features, giving each provider a chance to act on something. Created a common method in a new ApiUtils class to faciliate it. Renamed to FeatureApiUtils per review comment.
