42 * #GDBusObjectManagerServer is used to export #GDBusObject instances using
43 * the standardized <ulink

46 * and properties in a single call. Additionally, any change in the
47 * object hierarchy is broadcast using signals. This means that D-Bus
48 * clients can keep caches up to date by only listening to D-Bus
51 * See #GDBusObjectManagerClient for the client-side code that is
52 * intended to be used with #GDBusObjectManagerServer or any D-Bus
