class Gio::DBusObjectManagerServer

Overview

#GDBusObjectManagerServer is used to export #GDBusObject 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 #GDBusObjectManagerClient 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.

Constructor Detail

def self.new(object_path : String) #

Creates a new #GDBusObjectManagerServer object.

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


def self.new #

Initialize a new DBusObjectManagerServer.


def self.new(*, connection : Gio::DBusConnection? = nil, object_path : String? = nil) #

Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

def connection : Gio::DBusConnection? #

Gets the #GDBusConnection used by @manager.


def connection=(connection : Gio::DBusConnection?) : Nil #

Exports all objects managed by @manager on @connection. If @connection is %NULL, stops exporting objects.


def export(object : Gio::DBusObjectSkeleton) : Nil #

Exports @object on @manager.

If there is already a #GDBusObject 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.


def export_uniquely(object : Gio::DBusObjectSkeleton) : Nil #

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 #GDBusObjectProxy:g-object-path property of @object may be modified.


def is_exported(object : Gio::DBusObjectSkeleton) : Bool #

Returns whether @object is currently exported on @manager.


def object_path : String #

def object_path=(value : String) : String #

def unexport(object_path : String) : 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.
