From 173c4dbea9a1175a6f18031a221bb701deeecaa7 Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Mon, 9 Sep 2019 16:51:32 -0400 Subject: Create StandardYamlCoder Created StandardYamlCoder which is like a StandardCoder, except that the original converts to/from JSON, while the new class converts to/from YAML. Also added YamlMessageBodyHandler and incorporated it into the http server so that it supports a media type of */yaml.
