44 * SECTION:gdbusobjectmanagerclient
45 * @short_description: Client-side object manager
48 * #GDBusObjectManagerClient is used to create, monitor and delete object
49 * proxies for remote objects exported by a #GDBusObjectManagerServer (or any
50 * code implementing the <ulink
51 * url="http://dbus.freedesktop.org/doc/dbus-specification.html#standard-interfaces-objectmanager">org.freedesktop.DBus.ObjectManager</ulink>
54 * Once an instance of this type has been created, you can connect to
55 * the #GDBusObjectManager::object-added and
56 * #GDBusObjectManager::object-removed signals and inspect the
57 * #GDBusObjectProxy objects returned by
58 * g_dbus_object_manager_get_objects().
60 * If the name for a #GDBusObjectManagerClient is not owned by anyone at
61 * object construction time, the default behavior is to request the
62 * message bus to launch an owner for the name. This behavior can be
63 * disabled using the %G_DBUS_OBJECT_MANAGER_CLIENT_FLAGS_DO_NOT_AUTO_START
64 * flag. It's also worth noting that this only works if the name of
65 * interest is activatable in the first place. E.g. in some cases it
66 * is not possible to launch an owner for the requested name. In this
67 * case, #GDBusObjectManagerClient object construction still succeeds but
68 * there will be no object proxies
69 * (e.g. g_dbus_object_manager_get_objects() returns the empty list) and
70 * the #GDBusObjectManagerClient:name-owner property is %NULL.
72 * The owner of the requested name can come and go (for example
73 * consider a system service being restarted) – #GDBusObjectManagerClient
74 * handles this case too; simply connect to the #GObject::notify
75 * signal to watch for changes on the #GDBusObjectManagerClient:name-owner
76 * property. When the name owner vanishes, the behavior is that
77 * #GDBusObjectManagerClient:name-owner is set to %NULL (this includes
78 * emission of the #GObject::notify signal) and then
79 * #GDBusObjectManager::object-removed signals are synthesized
80 * for all currently existing object proxies. Since
81 * #GDBusObjectManagerClient:name-owner is %NULL when this happens, you can
82 * use this information to disambiguate a synthesized signal from a
83 * genuine signal caused by object removal on the remote
84 * #GDBusObjectManager. Similarly, when a new name owner appears,
85 * #GDBusObjectManager::object-added signals are synthesized
86 * while #GDBusObjectManagerClient:name-owner is still %NULL. Only when all
87 * object proxies have been added, the #GDBusObjectManagerClient:name-owner
88 * is set to the new name owner (this includes emission of the
89 * #GObject::notify signal). Furthermore, you are guaranteed that
90 * #GDBusObjectManagerClient:name-owner will alternate between a name owner
91 * (e.g. <literal>:1.42</literal>) and %NULL even in the case where
92 * the name of interest is atomically replaced
94 * Ultimately, #GDBusObjectManagerClient is used to obtain #GDBusProxy
95 * instances. All signals (including the
96 * <literal>org.freedesktop.DBus.Properties::PropertiesChanged</literal>
97 * signal) delivered to #GDBusProxy instances are guaranteed to
98 * originate from the name owner. This guarantee along with the
99 * behavior described above, means that certain race conditions
100 * including the <emphasis><quote>half the proxy is from the old owner
101 * and the other half is from the new owner</quote></emphasis> problem
104 * To avoid having the application connect to signals on the returned
105 * #GDBusObjectProxy and #GDBusProxy objects, the
106 * #GDBusObject::interface-added,
107 * #GDBusObject::interface-removed,
108 * #GDBusProxy::g-properties-changed and
109 * #GDBusProxy::g-signal signals
110 * are also emitted on the #GDBusObjectManagerClient instance managing these
111 * objects. The signals emitted are
112 * #GDBusObjectManager::interface-added,
113 * #GDBusObjectManager::interface-removed,
114 * #GDBusObjectManagerClient::interface-proxy-properties-changed and
115 * #GDBusObjectManagerClient::interface-proxy-signal.
117 * Note that all callbacks and signals are emitted in the
118 * <link linkend="g-main-context-push-thread-default">thread-default main loop</link>
119 * that the #GDBusObjectManagerClient object was constructed
120 * in. Additionally, the #GDBusObjectProxy and #GDBusProxy objects
121 * originating from the #GDBusObjectManagerClient object will be created in
122 * the same context and, consequently, will deliver signals in the
