From b020843d050ece966c4652d00ff7dead897be917 Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Tue, 26 Feb 2019 14:09:35 -0500 Subject: Add code to publish to PDP Added code to take an arbitrary object and send it to PDPs using a topic sink. Does not include the code or properties needed to configure the topic. Fixed method name - test case does not cover what the method name implied. Fixed some comments. Add test to verify that the PdpClient works with a real TopicSink. Moved coder classes to policy/common.
