Detailed Description

Abstract base class for D-Bus interfaces on the service side.

Since glibmm 2.38:

Constructor & Destructor Documentation

override noexcept

Member Function Documentation

void Gio::DBus::InterfaceSkeleton::export_interface_skeleton ( const Glib::RefPtr < Connection >& connection ,
const Glib::ustring & object_path
)

Exports interface at object_path on connection .

This can be called multiple times to export the same interface onto multiple connections however the object_path provided must be the same for all connections.

Use g_dbus_interface_skeleton_unexport() to unexport the object.

Since glibmm 2.30:
Parameters
connection A DBusConnection to export interface on.
object_path The path to export the interface at.
Returns
true if the interface was exported on connection , otherwise false with error set.
void Gio::DBus::InterfaceSkeleton::flush ( )

If interface has outstanding changes, request for these changes to be emitted immediately.

For example, an exported D-Bus interface may queue up property changes and emit the org.freedesktop.DBus.Properties::Propert ` signal later (e.g. in an idle handler). This technique is useful for collapsing multiple property changes into one.

Since glibmm 2.30:
Glib::RefPtr < Connection > Gio::DBus::InterfaceSkeleton::get_connection ( )

Gets the first connection that interface is exported on, if any.

Since glibmm 2.30:

A DBusConnection or nullptr if interface is not exported anywhere. Do not free, the object belongs to interface .
Glib::RefPtr <const Connection > Gio::DBus::InterfaceSkeleton::get_connection ( ) const

Gets the first connection that interface is exported on, if any.

Since glibmm 2.30:
Returns
A DBusConnection or nullptr if interface is not exported anywhere. Do not free, the object belongs to interface .
std::vector < Glib::RefPtr < Connection > > Gio::DBus::InterfaceSkeleton::get_connections ( )

Gets a list of the connections that interface is exported on.

Since glibmm 2.32:
Returns
A list of all the connections that interface is exported on. The returned list should be freed with Glib::list_free() after each element has been freed with Glib::object_unref().
std::vector < Glib::RefPtr <const Connection > > Gio::DBus::InterfaceSkeleton::get_connections ( ) const

Gets a list of the connections that interface is exported on.

Since glibmm 2.32:
Returns

Returns
One or more flags from the DBusInterfaceSkeletonFlags enumeration.
Glib::RefPtr < InterfaceInfo > Gio::DBus::InterfaceSkeleton::get_info ( )

Gets D-Bus introspection information for the D-Bus interface implemented by interface .

Glib::RefPtr <const InterfaceInfo > Gio::DBus::InterfaceSkeleton::get_info ( ) const

Gets D-Bus introspection information for the D-Bus interface implemented by interface .

Gets all D-Bus properties for interface .

Since glibmm 2.30:
Returns
A Variant of type ['a{sv}'][G-VARIANT-TYPE-VARDICT:CAPS]. Free with Glib::variant_unref().
static GType Gio::DBus::InterfaceSkeleton::get_type ( )
static

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

InterfaceSkeleton & Gio::DBus::InterfaceSkeleton::operator= ( InterfaceSkeleton && src )
noexcept
Glib::PropertyProxy < InterfaceSkeletonFlags > Gio::DBus::InterfaceSkeleton::property_g_flags ( )

Flags from the DBusInterfaceSkeletonFlags enumeration.

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 < InterfaceSkeletonFlags > Gio::DBus::InterfaceSkeleton::property_g_flags ( ) const

void Gio::DBus::InterfaceSkeleton::set_flags ( InterfaceSkeletonFlags flags )

Sets flags describing what the behavior of skeleton should be.

Since glibmm 2.30:
Parameters
flags Flags from the DBusInterfaceSkeletonFlags enumeration.
Glib::SignalProxy < bool,const Glib::RefPtr < MethodInvocation >& > Gio::DBus::InterfaceSkeleton::signal_authorize_method ( )
Slot Prototype:
bool on_my_authorize_method(const Glib::RefPtr<MethodInvocation>& invocation)

Emitted when a method is invoked by a remote caller and used to determine if the method call is authorized.

Note that this signal is emitted in a thread dedicated to handling the method call so handlers are allowed to perform blocking IO. This means that it is appropriate to call e.g. polkit_authority_check_authorization_sync() with the POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION flag set.

If false is returned then no further handlers are run and the signal handler must take a reference to invocation and finish handling the call (e.g. return an error via g_dbus_method_invocation_return_error()).

Otherwise, if true is returned, signal emission continues. If no handlers return false , then the method is dispatched. If interface has an enclosing DBusObjectSkeleton, then the DBusObjectSkeleton::signal_authorize_method() signal handlers run before the handlers for this signal.

The default class handler just returns true .

Please note that the common case is optimized: if no signals handlers are connected and the default class handler isn't overridden (for both interface and the enclosing DBusObjectSkeleton, if any) and DBusInterfaceSkeleton::property_g_flags() does not have the DBUS_INTERFACE_SKELETON_FLAGS_HANDLE_METHOD_INVOCATIONS_IN_THREAD flags set, no dedicated thread is ever used and the call will be handled in the same thread as the object that interface belongs to was exported in.

Since glibmm 2.30:
Parameters
invocation A DBusMethodInvocation.
Returns
true if the call is authorized, false otherwise.
void Gio::DBus::InterfaceSkeleton::unexport ( )

Stops exporting interface on all connections it is exported on.

To unexport interface from only a single connection, use g_dbus_interface_skeleton_unexport_from_connection()

Since glibmm 2.30:
void Gio::DBus::InterfaceSkeleton::unexport_from_connection ( const Glib::RefPtr < Connection >& connection )

Stops exporting interface on connection .

To stop exporting on all connections the interface is exported on, use g_dbus_interface_skeleton_unexport().

Since glibmm 2.32:
Parameters
connection A DBusConnection.
