## Detailed Description

Service-side object manager.

Gio::DBus::ObjectManagerServer is used to export Gio::DBus::Object instances using the standardized org.freedesktop.DBus.ObjectManager interface. For example, remote D-Bus clients can get all objects and properties in a single call. Additionally, any change in the object hierarchy is broadcast using signals. This means that D-Bus clients can keep caches up to date by only listening to D-Bus signals.

The recommended path to export an object manager at is the path form of the well-known name of a D-Bus service, or below. For example, if a D-Bus service is available at the well-known name `net.example.ExampleService1`, the object manager should typically be exported at `/net/example/ExampleService1`, or below (to allow for multiple object managers in a service).

It is supported, but not recommended, to export an object manager at the root path, `/`.

See Gio::DBus::ObjectManagerClient for the client-side code that is intended to be used with ObjectManagerServer or any D-Bus object implementing the org.freedesktop.DBus.ObjectManager interface.

## Member Function Documentation

static Glib::RefPtr<ObjectManagerServer> Gio::DBus::ObjectManagerServer::create | ( | const Glib::ustring& | object_path | ) |
| static

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

The returned server isn't yet exported on any connection. To do so, use set_connection(). Normally you want to export all of your objects before doing so to avoid Gio::DBus::ObjectManager::signal_interface_added() signals being emitted.

Parameters

  object_path | The object path to export the manager object at.

Returns
  A new Gio::DBus::ObjectManagerServer object.

void Gio::DBus::ObjectManagerServer::export_object | ( | const Glib::RefPtr< Gio::DBus::ObjectSkeleton >& | object | ) |

Exports object on manager.

If there is already a DBusObject exported at the object path, then the old object is removed.

The object path for object must be in the hierarchy rooted by the object path for manager.

Note that manager will take a reference on object for as long as it is exported.

Since glibmm 2.30:

Parameters

  object | A DBusObjectSkeleton.

void Gio::DBus::ObjectManagerServer::export_uniquely | ( | const Glib::RefPtr< Gio::DBus::ObjectSkeleton >& | object | ) |

Like g_dbus_object_manager_server_export() but appends a string of the form _N (with N being a natural number) to object's object path if an object with the given path already exists.

As such, the DBusObjectProxy::property_g_object_path() property of object may be modified.

Since glibmm 2.30:

Parameters

  object | An object.

Glib::RefPtr<Connection> Gio::DBus::ObjectManagerServer::get_connection | ( |  | ) |

Gets the DBusConnection used by manager.

Since glibmm 2.30:

Returns
  A DBusConnection object or `nullptr` if manager isn't exported on a connection. The returned object should be freed with Glib::object_unref().

Glib::RefPtr<const Connection> Gio::DBus::ObjectManagerServer::get_connection | ( |  | ) | const

Gets the DBusConnection used by manager.

Since glibmm 2.30:

Returns
  A DBusConnection object or `nullptr` if manager isn't exported on a connection. The returned object should be freed with Glib::object_unref().

static GType Gio::DBus::ObjectManagerServer::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

GDBusObjectManagerServer* Gio::DBus::ObjectManagerServer::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GDBusObjectManagerServer* Gio::DBus::ObjectManagerServer::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

GDBusObjectManagerServer* Gio::DBus::ObjectManagerServer::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

bool Gio::DBus::ObjectManagerServer::is_exported | ( | const Glib::RefPtr< Gio::DBus::ObjectSkeleton >& | object | ) | const

Returns whether object is currently exported on manager.

Since glibmm 2.34:

Parameters

  object | An object.

Returns
  `true` if object is exported.

ObjectManagerServer& Gio::DBus::ObjectManagerServer::operator= | ( | ObjectManagerServer&& | src | ) |
| noexcept

Glib::PropertyProxy< Glib::RefPtr<Connection> > Gio::DBus::ObjectManagerServer::property_connection | ( |  | ) |

The DBusConnection to export objects on.

Since glibmm 2.30:

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Connection> > Gio::DBus::ObjectManagerServer::property_connection | ( |  | ) | const

The DBusConnection to export objects on.

Since glibmm 2.30:

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< Glib::ustring > Gio::DBus::ObjectManagerServer::property_object_path | ( |  | ) | const

The object path to register the manager object at.

Since glibmm 2.30:

Default value: ""

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

void Gio::DBus::ObjectManagerServer::set_connection | ( | const Glib::RefPtr< Connection >& | connection | ) |

Exports all objects managed by manager on connection.

If connection is `nullptr`, stops exporting objects.

Parameters

  connection | A DBusConnection or `nullptr`.

bool Gio::DBus::ObjectManagerServer::unexport | ( | const Glib::ustring& | object_path | ) |

If manager has an object at path, removes the object.

Otherwise does nothing.

Note that object_path must be in the hierarchy rooted by the object path for manager.

Since glibmm 2.30:

Parameters

  object_path | An object path.

Returns
  `true` if object at object_path was removed, `false` otherwise.

## Friends And Related Function Documentation

Glib::RefPtr< Gio::DBus::ObjectManagerServer > wrap | ( | GDBusObjectManagerServer * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
