From 59c38b6b3dfbd43c876f85ffb1e4b484951ced44 Mon Sep 17 00:00:00 2001 From: Pamela Dragosh Date: Fri, 15 Mar 2019 14:30:00 -0400 Subject: Started with test decision JSON objects. Added new Policy Finder Factory that ONAP will use and got the code working with new policy/models (see other review which will have to be merged first). Added some new conversion methods to convert from a Xacml request to an Onap request. Added some property methods for XACML Properties objects and JUnit tests. Started filling in some Guard application details and combining code.
