Gio.DBusObjectManagerServer

class — extends GObject.Object, DBusObjectManager

GDBusObjectManagerServer is used to export DBusObject 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 DBusObjectManagerClient for the client-side code that is intended to be used with GDBusObjectManagerServer or any D-Bus object implementing the org.freedesktop.DBus.ObjectManager interface.

Constructors

new

@classmethod
def new(cls, object_path: str) -> DBusObjectManagerServer

Creates a new DBusObjectManagerServer object.

The returned server isn't yet exported on any connection. To do so, use DBusObjectManagerServer.set_connection. Normally you want to export all of your objects before doing so to avoid InterfacesAdded signals being emitted.

Parameters:

  • object_path — The object path to export the manager object at.

Methods

export

def export(self, object: DBusObjectSkeleton) -> None

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.

Parameters:

export_uniquely

def export_uniquely(self, object: DBusObjectSkeleton) -> None

Like DBusObjectManagerServer.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:g-object-path property of object may be modified.

Parameters:

  • object — An object.

get_connection

def get_connection(self) -> DBusConnection | None

Gets the DBusConnection used by manager.

is_exported

def is_exported(self, object: DBusObjectSkeleton) -> bool

Returns whether object is currently exported on manager.

Parameters:

  • object — An object.

set_connection

def set_connection(self, connection: DBusConnection | None = ...) -> None

Exports all objects managed by manager on connection. If connection is None, stops exporting objects.

Parameters:

unexport

def unexport(self, object_path: str) -> bool

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.

Parameters:

  • object_path — An object path.

Properties

connection

connection: DBusConnection  # read/write

The DBusConnection to export objects on.

object_path

object_path: str  # read/write

The object path to register the manager object at.
