|
|
*
|
|
* - TestIface1 is added before the class is initialized
|
|
* - TestIface2 is added in base_object_base_init()
|
|
* - TestIface3 is added in test_iface1_base_init()
|
|
* - TestIface4 is added in test_object_class_init()
|

* - TestIface5 is added in test_object_test_iface1_init()
|
|
* - TestIface6 is added after the class is initialized
