  * The first example of such a QOM method was #CPUClass.reset,
  * another example is #DeviceClass.realize.
+ *
+ * # Standard type declaration and definition macros #
+ *
+ * A lot of the code outlined above follows a standard pattern and naming
+ * convention. To reduce the amount of boilerplate code that needs to be
+ * written for a new type there are two sets of macros to generate the
+ * common parts in a standard format.
+ *
+ * A type is declared using the OBJECT_DECLARE macro family. In types
+ * which do not require any virtual functions in the class, the
+ * OBJECT_DECLARE_SIMPLE_TYPE macro is suitable, and is commonly placed
+ * in the header file:
+ *
+ * <example>
+ *   <title>Declaring a simple type</title>
+ *   <programlisting>
+ *     OBJECT_DECLARE_SIMPLE_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE)
+ *   </programlisting>
+ * </example>
+ *
+ * This is equivalent to the following:
+ *
+ * <example>
+ *   <title>Expansion from declaring a simple type</title>
+ *   <programlisting>
+ *     typedef struct MyDevice MyDevice;
+ *     typedef struct MyDeviceClass MyDeviceClass;
+ *
+ *     G_DEFINE_AUTOPTR_CLEANUP_FUNC(MyDeviceClass, object_unref)
+ *
+ *     #define MY_DEVICE_GET_CLASS(void *obj) \
+ *             OBJECT_GET_CLASS(MyDeviceClass, obj, TYPE_MY_DEVICE)
+ *     #define MY_DEVICE_CLASS(void *klass) \
+ *             OBJECT_CLASS_CHECK(MyDeviceClass, klass, TYPE_MY_DEVICE)
+ *     #define MY_DEVICE(void *obj)
+ *             OBJECT_CHECK(MyDevice, obj, TYPE_MY_DEVICE)
+ *
+ *     struct MyDeviceClass {
+ *         DeviceClass parent_class;
+ *     };
+ *   </programlisting>
+ * </example>
+ *
+ * The 'struct MyDevice' needs to be declared separately.
+ * If the type requires virtual functions to be declared in the class
+ * struct, then the alternative OBJECT_DECLARE_TYPE() macro can be
+ * used. This does the same as OBJECT_DECLARE_SIMPLE_TYPE(), but without
+ * the 'struct MyDeviceClass' definition.
+ *
+ * To implement the type, the OBJECT_DEFINE macro family is available.
+ * In the simple case the OBJECT_DEFINE_TYPE macro is suitable:
+ *
+ * <example>
+ *   <title>Defining a simple type</title>
+ *   <programlisting>
+ *     OBJECT_DEFINE_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE)
+ *   </programlisting>
+ * </example>
+ *
+ * This is equivalent to the following:
+ *
+ * <example>
+ *   <title>Expansion from defining a simple type</title>
+ *   <programlisting>
+ *     static void my_device_finalize(Object *obj);
+ *     static void my_device_class_init(ObjectClass *oc, void *data);
+ *     static void my_device_init(Object *obj);
+ *
+ *     static const TypeInfo my_device_info = {
+ *         .parent = TYPE_DEVICE,
+ *         .name = TYPE_MY_DEVICE,
+ *         .instance_size = sizeof(MyDevice),
+ *         .instance_init = my_device_init,
+ *         .instance_finalize = my_device_finalize,
+ *         .class_size = sizeof(MyDeviceClass),
+ *         .class_init = my_device_class_init,
+ *     };
+ *
+ *     static void
+ *     my_device_register_types(void)
+ *     {
+ *         type_register_static(&my_device_info);
+ *     }
+ *     type_init(my_device_register_types);
+ *   </programlisting>
+ * </example>
+ *
+ * This is sufficient to get the type registered with the type
+ * system, and the three standard methods now need to be implemented
+ * along with any other logic required for the type.
+ *
+ * If the type needs to implement one or more interfaces, then the
+ * OBJECT_DEFINE_TYPE_WITH_INTERFACES() macro can be used instead.
+ * This accepts an array of interface type names.
+ *
+ * <example>
+ *   <title>Defining a simple type implementing interfaces</title>
+ *   <programlisting>
+ *     OBJECT_DEFINE_TYPE_WITH_INTERFACES(MyDevice, my_device,
+ *                                        MY_DEVICE, DEVICE,
+ *                                        { TYPE_USER_CREATABLE }, { NULL })
+ *   </programlisting>
+ * </example>
+ *
+ * If the type is not intended to be instantiated, then then
+ * the OBJECT_DEFINE_ABSTRACT_TYPE() macro can be used instead:
+ *
+ * <example>
+ *   <title>Defining a simple type</title>
+ *   <programlisting>
+ *     OBJECT_DEFINE_ABSTRACT_TYPE(MyDevice, my_device, MY_DEVICE, DEVICE)
+ *   </programlisting>
+ * </example>
