From b909b14fe88c5fe8f096cf8b471a2aa799d84739 Mon Sep 17 00:00:00 2001 From: Pamela Dragosh Date: Sat, 9 Mar 2019 11:48:44 -0500 Subject: Monitoring policy creation foundation Upgrde to xacml v2.0.0 release artifact. Some re-arrangement of classes. New class to support a common dictionary among the monitoring applications. I may move it to a common under the main since some of the values are shareable. Created application service provider, so the XACML main knows what policy types are pre-loaded and can report them back to the PAP. struggled with cucumber, which does not create TemporaryFolder although the documentation says its supported. Added a new Policy Finder specific to ONAP which does quicker job to load policies.
