public class DBusInterfaceVTable extends Record
Virtual table for handling properties and method calls for a D-Bus
interface.

Since 2.38, if you want to handle getting/setting D-Bus properties
asynchronously, give %NULL as your get_property() or set_property()
function. The D-Bus call will be directed to your @method_call function,
with the provided @interface_name set to "org.freedesktop.DBus.Properties".

Ownership of the #GDBusMethodInvocation object passed to the
method_call() function is transferred to your handler; you must
call one of the methods of #GDBusMethodInvocation to return a reply
(possibly empty), or an error. These functions also take ownership
of the passed-in invocation object, so unless the invocation
object has otherwise been referenced, it will be then be freed.
Calling one of these functions may be done within your
method_call() implementation but it also can be done at a later
point to handle the method asynchronously.

The usual checks on the validity of the calls is performed. For
`Get` calls, an error is automatically returned if the property does
not exist or the permissions do not allow access. The same checks are
performed for `Set` calls, and the provided value is also checked for
being the correct type.

For both `Get` and `Set` calls, the #GDBusMethodInvocation
passed to the @method_call handler can be queried with
g_dbus_method_invocation_get_property_info() to get a pointer
to the #GDBusPropertyInfo of the property.

If you have readable properties specified in your interface info,
you must ensure that you either provide a non-%NULL @get_property()
function or provide implementations of both the `Get` and `GetAll`
methods on org.freedesktop.DBus.Properties interface in your @method_call
function. Note that the required return type of the `Get` call is
`(v)`, not the type of the property. `GetAll` expects a return value
of type `a{sv}`.

If you have writable properties specified in your interface info,
you must ensure that you either provide a non-%NULL @set_property()
function or provide an implementation of the `Set` call. If implementing
the call, you must return the value of type %G_VARIANT_TYPE_UNIT.
