## Detailed Description

Client-side object manager.

Gio::DBus::ObjectManagerClient is used to create, monitor and delete object proxies for remote objects exported by a Gio::DBus::ObjectManagerServer (or any code implementing the org.freedesktop.DBus.ObjectManager interface.

Once an instance of this type has been created, you can connect to Gio::DBus::ObjectManager::signal_object_added() and Gio::DBus::ObjectManager::signal_object_removed() and inspect the Gio::DBus::Object objects returned by Gio::DBus::ObjectManager::get_objects().

If the name for a Gio::DBus::ObjectManagerClient 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 Gio::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, ObjectManagerClient object construction still succeeds but there will be no object proxies (e.g. get_objects() returns an empty vector) and property_name_owner() is an empty string.

The owner of the requested name can come and go (for example consider a system service being restarted) – ObjectManagerClient handles this case too; simply connect to property_name_owner().signal_changed() to watch for changes on property_name_owner(). When the name owner vanishes, the behavior is that property_name_owner() is set to an empty string (this includes emission of signal_changed()) and then signal_object_removed() signals are synthesized for all currently existing object proxies. Since property_name_owner() is an empty string when this happens, you can use this information to disambiguate a synthesized signal from a genuine signal caused by object removal on the remote Gio::DBus::ObjectManager. Similarly, when a new name owner appears, signal_object_added() signals are synthesized while property_namename_owner() is still an empty string. Only when all object proxies have been added, property_name_owner() is set to the new name owner (this includes emission of the signal_changed()). Furthermore, you are guaranteed that property_name_owner() will alternate between a name owner (e.g. `:1.42`) and an empty string even in the case where the name of interest is atomically replaced.

Ultimately, ObjectManagerClient is used to obtain Gio::DBus::Proxy instances. All signals (including the org.freedesktop.DBus.Properties::PropertiesChanged signal) delivered to Gio::DBus::Proxy 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 Gio::DBus::Object and Gio::DBus::Proxy objects, Gio::DBus::Object::signal_interface_added(), Gio::DBus::Object::signal_interface_removed(), Gio::DBus::Proxy::signal_properties_changed() and Gio::DBus::Proxy::signal_signal() are also emitted on the ObjectManagerClient instance managing these objects. The signals emitted are signal_interface_added(), signal_interface_removed(), signal_interface_proxy_properties_changed() and signal_interface_proxy_signal().

Note that all callbacks and signals are emitted in the thread-default main context that the ObjectManagerClient object was constructed in. Additionally, the Gio::DBus::ObjectProxy and Gio::DBus::Proxy objects originating from the ObjectManagerClient object will be created in the same context and, consequently, will deliver signals in the same main loop.

## Member Typedef Documentation

## ◆ MapChangedProperties

using Gio::DBus::ObjectManagerClient::MapChangedProperties = std::map<Glib::ustring, Glib::VariantBase>

## ◆ SlotProxyType

using Gio::DBus::ObjectManagerClient::SlotProxyType

Initial value:
sigc::slot<GType(const Glib::RefPtr<Gio::DBus::ObjectManagerClient>&,
const Glib::ustring&, const Glib::ustring&)>
Glib::RefPtr
RefPtr<> is a reference-counting shared smartpointer.
Definition refptr.h:52
Glib::ustring
Glib::ustring has much the same interface as std::string, but contains Unicode characters encoded as ...
Definition ustring.h:327
sigc::slot

A slot that will be called to determine the GType to use for an interface proxy (if interface_name is not an empty string) or object proxy (if interface_name is an empty string).

This function is called in the thread-default main loop that manager was constructed in.

For instance:

GType on_proxy_type(const Glib::RefPtr<Gio::DBus::ObjectManagerClient>& manager,
const Glib::ustring& object_path, const Glib::ustring& interface_name);

Parameters

  manager | A Gio::DBus::ObjectManagerClient.
  object_path | The object path of the remote object.
  interface_name | The interface name of the remote object, or an empty string if a GDBusObjectProxy GType is requested.

Returns
  A GType to use for the remote object. The returned type must be a GDBusProxy or GDBusObjectProxy-derived type.

## ◆ create()

static void Gio::DBus::ObjectManagerClient::create | ( | const Glib::RefPtr< Connection > & | connection,
|  | const Glib::ustring & | name,
|  | const Glib::ustring & | object_path,
|  | const SlotAsyncReady & | slot_async_ready,
|  | const Glib::RefPtr< Cancellable > & | cancellable = {},
|  | const SlotProxyType & | slot_proxy_type = {},
|  | ObjectManagerClientFlags | flags = OBJECT_MANAGER_CLIENT_FLAGS_NONE )
| static

Creates a new Gio::DBus::ObjectManagerClient object.

This is an asynchronous failable constructor. When the result is ready, slot_async_ready will be invoked in the thread-default main context of the thread you are calling this method from. You can then call create_finish() to get the result. See create_sync() for the synchronous version.

Parameters

  connection | A Gio::DBus::Connection.
  name | The owner of the control object (unique or well-known name).
  object_path | The object path of the control object.
  slot_async_ready | A SlotAsyncReady slot to call when the request is satisfied.
  cancellable | A Cancellable or an empty Glib::RefPtr.
  slot_proxy_type | A SlotProxyType slot, or an empty slot to always construct GDBusProxy or GDBusObjectProxy proxies.
  flags | Zero or more flags from the Gio::DBus::ObjectManagerClientFlags enumeration.

## ◆ create_finish()

static Glib::RefPtr< Gio::DBus::ObjectManagerClient > Gio::DBus::ObjectManagerClient::create_finish | ( | const Glib::RefPtr< AsyncResult > & | res | ) |
| static

Finishes an operation started with create().

Parameters

  res | An AsyncResult obtained from the SlotAsyncReady passed to create().

Returns
  A Gio::DBus::ObjectManagerClient object. If an error has occurred, a Glib::Error is thrown and nothing is returned.

Exceptions

  Glib::Error. |

## ◆ create_for_bus()

static void Gio::DBus::ObjectManagerClient::create_for_bus | ( | BusType | bus_type,
|  | const Glib::ustring & | name,

|  | ObjectManagerClientFlags | flags = OBJECT_MANAGER_CLIENT_FLAGS_NONE )
| static

Creates a new Gio::DBus::ObjectManagerClient object.

Like create() but takes a Gio::DBus::BusType instead of a Gio::DBus::Connection.

This is an asynchronous failable constructor. When the result is ready, slot_async_ready will be invoked in the thread-default main context of the thread you are calling this method from. You can then call create_for_bus_finish() to get the result. See create_for_bus_sync() for the synchronous version.

Parameters

  bus_type | A Gio::DBus::BusType.
  name | The owner of the control object (unique or well-known name).
  object_path | The object path of the control object.
  slot_async_ready | A SlotAsyncReady slot to call when the request is satisfied.
  cancellable | A Cancellable or an empty Glib::RefPtr.
  slot_proxy_type | A SlotProxyType slot, or an empty slot to always construct GDBusProxy or GDBusObjectProxy proxies.

Flags: Run Last

Emitted when one or more D-Bus properties on proxy changes. The local cache has already been updated when this signal fires. Note that both changed_properties and invalidated_properties are guaranteed to never be `nullptr` (either may be empty though).

This signal exists purely as a convenience to avoid having to connect signals to all interface proxies managed by manager.

This signal is emitted in the [thread-default main context][g-main-context-push-thread-default] that manager was constructed in.

Since glibmm 2.30

Parameters

  object_proxy | The DBusObjectProxy on which an interface has properties that are changing.
  interface_proxy | The DBusProxy that has properties that are changing.
  changed_properties | A Variant containing the properties that changed (type: `a{sv}`).
  invalidated_properties | A `nullptr` terminated array of properties that were invalidated.

Flags: Run Last

Emitted when a D-Bus signal is received on interface_proxy.

This signal exists purely as a convenience to avoid having to connect signals to all interface proxies managed by manager.

This signal is emitted in the [thread-default main context][g-main-context-push-thread-default] that manager was constructed in.

Since glibmm 2.30

Parameters

  object_proxy | The DBusObjectProxy on which an interface is emitting a D-Bus signal.
  interface_proxy | The DBusProxy that is emitting a D-Bus signal.
  sender_name | The sender of the signal or `nullptr` if the connection is not a bus connection.
  signal_name | The signal name.
  parameters | A Variant tuple with parameters for the signal.
