59 | * This list, global to the library, keeps all component classes that |
60 | * have a reference to their shared library handles. It allows iteration | |
61 | * on all component classes still present when the destructor executes | |
62 | * to release the shared library handle references they might still have. | |
55bb57e0 | 63 | * |
bfa9a4be | 64 | * The list items are the component classes created with |
55bb57e0 PP |
65 | * bt_plugin_add_component_class(). They keep the shared library handle |
66 | * object created by their plugin alive so that the plugin's code is | |
67 | * not discarded when it could still be in use by living components | |
68 | * created from those component classes: | |
69 | * | |
bfa9a4be | 70 | * [component] --ref-> [component class]-> [shlib handle] |
55bb57e0 | 71 | * |
bfa9a4be | 72 | * It allows this use-case: |
55bb57e0 | 73 | * |
c8db3219 | 74 | * my_plugins = bt_plugin_find_all_from_file("/path/to/my-plugin.so"); |
55bb57e0 PP |
75 | * // instantiate components from a plugin's component classes |
76 | * // put plugins and free my_plugins here | |
77 | * // user code of instantiated components still exists | |
78 | * | |
bfa9a4be MD |
79 | * An entry is removed from this list when a component class is |
80 | * destroyed thanks to a custom destroy listener. When the entry is | |
81 | * removed, the entry is removed from the list, and we release the | |
82 | * reference on the shlib handle. Assuming the original plugin object | |
83 | * which contained some component classes is put first, when the last | |
84 | * component class is removed from this list, the shared library handle | |
85 | * object's reference count falls to zero and the shared library is | |
86 | * finally closed. | |
