Instances of the 'GI.Gio.Objects.DBusMethodInvocation.DBusMethodInvocation' class are used when
handling D-Bus method calls. It provides a way to asynchronously
return results and errors.

The normal way to obtain a 'GI.Gio.Objects.DBusMethodInvocation.DBusMethodInvocation' object is to receive
it as an argument to the @/handle_method_call()/@ function in a
'GI.Gio.Structs.DBusInterfaceVTable.DBusInterfaceVTable' that was passed to @/g_dbus_connection_register_object()/@.
