+// ExportedObjectManager is a delegate that implements the
+// org.freedesktop.DBus.ObjectManager interface on behalf of another
+// object. It handles sending signals when new interfaces are added.

+// it allows objects to expose an object manager interface rather than the
+// properties interface.
+//
+//  Example usage:
+//
+//   class ExampleObjectManager {
+//    public:
+//     ExampleObjectManager(dbus::Bus* bus)
+//         : object_manager_(bus, "/my/objects/path") { }
