    /// interface).
    ///
    /// Once an instance of this type has been created, you can connect to

    /// [`object-removed`][struct@crate::DBusObjectManager#object-removed] signals] and inspect the
    /// [`DBusObjectProxy`][crate::DBusObjectProxy] objects returned by
    /// [`DBusObjectManagerExt::objects()`][crate::prelude::DBusObjectManagerExt::objects()].
    ///
    /// If the name for a `GDBusObjectManagerClient` is not owned by anyone at
    /// object construction time, the default behavior is to request the
    /// message bus to launch an owner for the name. This behavior can be
    /// disabled using the `G_DBUS_OBJECT_MANAGER_CLIENT_FLAGS_DO_NOT_AUTO_START`
    /// flag. It’s also worth noting that this only works if the name of
    /// interest is activatable in the first place. E.g. in some cases it
    /// is not possible to launch an owner for the requested name. In this
    /// case, `GDBusObjectManagerClient` object construction still succeeds but
    /// there will be no object proxies
    /// (e.g. [`DBusObjectManagerExt::objects()`][crate::prelude::DBusObjectManagerExt::objects()] returns the empty list) and
    /// the [`name-owner`][struct@crate::DBusObjectManagerClient#name-owner] property is `NULL`.
    ///
    /// The owner of the requested name can come and go (for example
    /// consider a system service being restarted) – `GDBusObjectManagerClient`
    /// handles this case too; simply connect to the [`notify`][struct@crate::glib::Object#notify]
    /// signal to watch for changes on the
    /// [`name-owner`][struct@crate::DBusObjectManagerClient#name-owner] property. When the name
    /// owner vanishes, the behavior is that
    /// [`name-owner`][struct@crate::DBusObjectManagerClient#name-owner] is set to `NULL` (this
    /// includes emission of the [`notify`][struct@crate::glib::Object#notify] signal) and then
    /// [`object-removed`][struct@crate::DBusObjectManager#object-removed] signals are synthesized
    /// for all currently existing object proxies. Since
    /// [`name-owner`][struct@crate::DBusObjectManagerClient#name-owner] is `NULL` when this
    /// happens, you can use this information to disambiguate a synthesized signal
    /// from a genuine signal caused by object removal on the remote
    /// [`DBusObjectManager`][crate::DBusObjectManager]. Similarly, when a new name owner appears,
    /// [`object-added`][struct@crate::DBusObjectManager#object-added] signals are synthesized
    /// while [`name-owner`][struct@crate::DBusObjectManagerClient#name-owner] is still `NULL`. Only
    /// when all object proxies have been added, the
    /// [`name-owner`][struct@crate::DBusObjectManagerClient#name-owner] is set to the new name
    /// owner (this includes emission of the [`notify`][struct@crate::glib::Object#notify] signal).
    /// Furthermore, you are guaranteed that
    /// [`name-owner`][struct@crate::DBusObjectManagerClient#name-owner] will alternate between a
    /// name owner (e.g. `:1.42`) and `NULL` even in the case where
    /// the name of interest is atomically replaced
    ///
    /// Ultimately, `GDBusObjectManagerClient` is used to obtain
    /// [`DBusProxy`][crate::DBusProxy] instances. All signals (including the
    /// `org.freedesktop.DBus.Properties::PropertiesChanged` signal)
    /// delivered to [`DBusProxy`][crate::DBusProxy] instances are guaranteed to originate
    /// from the name owner. This guarantee along with the behavior
    /// described above, means that certain race conditions including the
    /// “half the proxy is from the old owner and the other half is from
    /// the new owner” problem cannot happen.
    ///
    /// To avoid having the application connect to signals on the returned
    /// [`DBusObjectProxy`][crate::DBusObjectProxy] and [`DBusProxy`][crate::DBusProxy] objects, the
    /// [`interface-added`][struct@crate::DBusObject#interface-added],
    /// [`interface-removed`][struct@crate::DBusObject#interface-removed],
    /// [`g-properties-changed`][struct@crate::DBusProxy#g-properties-changed] and
