From 6fb97d3373232c16823f374d637533d36ac1049c Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Wed, 20 Mar 2019 16:40:02 -0400 Subject: Add wrapper for ServiceManager This makes it easier for a class to implement a Startable interface, using a ServiceManager internally, while preventing other classes from adding services to the manager (as would be the case if the class were simply subclassed from the ServiceManager). Changed the field name to be more descriptive. Fixed a typo in a comment.
