From f8d2c21bb589303febc11024f3cd667946f44459 Mon Sep 17 00:00:00 2001 From: Pamela Dragosh Date: Mon, 24 Aug 2020 15:50:31 -0400 Subject: Add new Match application to XACML Add new generic match application to XACML PDP. This app will allow ONAP users to design their own matchable policy types and use StdMatchableTranslator out-of-the box without any modification. Fills the gap left behind since "configure" via the Monitoring can support StdCombinedResultsTranslator, but the Optimization policy types have a specific "closest match" algorithm tied to them. Gives flexibility. removed unused import Issue-ID: POLICY-2596 Change-Id: I0aebae706fb9634e7bb13d78eff0ccc1ae4d752f Signed-off-by: Pamela Dragosh --- .../pdp/application/match/MatchPdpApplication.java | 85 ++++++++++++++++++++++ ...lication.common.XacmlApplicationServiceProvider | 1 + 2 files changed, 86 insertions(+) create mode 100644 applications/match/src/main/java/org/onap/policy/xacml/pdp/application/match/MatchPdpApplication.java create mode 100644 applications/match/src/main/resources/META-INF/services/org.onap.policy.pdp.xacml.application.common.XacmlApplicationServiceProvider (limited to 'applications/match/src/main') diff --git a/applications/match/src/main/java/org/onap/policy/xacml/pdp/application/match/MatchPdpApplication.java b/applications/match/src/main/java/org/onap/policy/xacml/pdp/application/match/MatchPdpApplication.java new file mode 100644 index 00000000..5f9cfa1a --- /dev/null +++ b/applications/match/src/main/java/org/onap/policy/xacml/pdp/application/match/MatchPdpApplication.java @@ -0,0 +1,85 @@ +/*- + * ============LICENSE_START======================================================= + * ONAP + * ================================================================================ + * Copyright (C) 2020 AT&T Intellectual Property.
