11 | * This hash table associates a BT component class object address to a | |
12 | * user-defined Python class (PyObject *). The keys and values are NOT | |
13 | * owned by this hash table. The Python class objects are owned by the | |
14 | * Python module, which should not be unloaded until it is not possible | |
15 | * to create a user Python component anyway. | |
16 | * | |
17 | * This hash table is written to when a user-defined Python component | |
18 | * class is created by one of the bt_bt2_component_class_*_create() | |
19 | * functions. | |
20 | * | |
21 | * This function is read from when a user calls bt_component_create() | |
22 | * with a component class pointer created by one of the functions above. | |
23 | * In this case, the original Python class needs to be found to | |
24 | * instantiate it and associate the created Python component object with | |
25 | * a BT component object instance. | |
