38 | * Plug-ins are owned by bt_component_factory and the bt_component_class-es | |
39 | * it provides. This means that its lifetime bound by either the component | |
40 | * factory's, or the concrete components' lifetime which may be in use and which | |
41 | * have hold a reference to their bt_component_class which, in turn, have a | |
42 | * reference to their plugin. | |
43 | * | |
44 | * This ensures that a plugin's library is not closed while it is being used | |
b8a06801 | 45 | * even if the bt_component_factory, which created its components, is destroyed. |
