29 | * This hash table associates a BT component class object address to a | |

32 | * Python module, which should not be unloaded until it is not possible | |
33 | * to create a user Python component anyway. | |
34 | * | |
35 | * This hash table is written to when a user-defined Python component | |
36 | * class is created by one of the bt_bt2_component_class_*_create() | |
37 | * functions. | |
38 | * | |
39 | * This function is read from when a user calls bt_component_create() | |
40 | * with a component class pointer created by one of the functions above. | |
41 | * In this case, the original Python class needs to be found to | |
42 | * instantiate it and associate the created Python component object with | |
43 | * a BT component object instance. | |
