From a2c5714eabfb87d4a59f106e418c967b599c4212 Mon Sep 17 00:00:00 2001 From: "mark.j.leonard" Date: Tue, 7 Aug 2018 16:43:55 +0100 Subject: Check getMetaData() return value for null Added code to check for null metadata. Decomposed existing methods to avoid Sonar complexity warnings. Renamed some variables for readability.
