35 * @short_description: Type module which allows extension registration.
36 *
37 * #BeanObjectModule is a subclass of #GTypeModule which allows registration
38 * of extensions. It will be used by C extensions implementors to register
39 * extension implementations from within the bean_register_types module
40 * function.
41 *
42 * Since libbean 1.22, @extension_type can be an Abstract #GType
43 * and not just an Interface #GType.
