## Detailed Description

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

Since glibmm 2.38:

## Constructor & Destructor Documentation

Gio::DBus::InterfaceSkeleton::InterfaceSkeleton | ( | InterfaceSkeleton&& | src | ) |
| noexcept

Gio::DBus::InterfaceSkeleton::~InterfaceSkeleton | ( |  | ) |
| overridenoexcept

## 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.

Exceptions

  Glib::Error |

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.PropertiesChanged` 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:

Returns
  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.

std::vector< Glib::RefPtr<const Connection> > Gio::DBus::InterfaceSkeleton::get_connections | ( |  | ) | const

  A list of all the connections that interface is exported on.

InterfaceSkeletonFlags Gio::DBus::InterfaceSkeleton::get_flags | ( |  | ) | const

Gets the DBusInterfaceSkeletonFlags that describes what the behavior of interface.

Since glibmm 2.30:

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.

Since glibmm 2.30:

Returns
  A DBusInterfaceInfo (never `nullptr`). Do not free.

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

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

Returns
  A DBusInterfaceInfo (never `nullptr`). Do not free.

Glib::ustring Gio::DBus::InterfaceSkeleton::get_object_path | ( |  | ) | const

Gets the object path that interface is exported on, if any.

Since glibmm 2.30:

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.

GDBusInterfaceSkeleton* Gio::DBus::InterfaceSkeleton::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GDBusInterfaceSkeleton* Gio::DBus::InterfaceSkeleton::gobj | ( |  | ) | const
| inline

Glib::PropertyProxy< InterfaceSkeletonFlags > Gio::DBus::InterfaceSkeleton::property_g_flags | ( |  | ) |

Flags from the DBusInterfaceSkeletonFlags enumeration.

Since glibmm 2.30:

Default value: DBUS_INTERFACE_SKELETON_FLAGS_NONE

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

Flags from the DBusInterfaceSkeletonFlags enumeration.

Since glibmm 2.30:

Default value: DBUS_INTERFACE_SKELETON_FLAGS_NONE

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::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)`

Flags: Run Last

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.
