Functions
| Function | Description |
|---|---|
| [list(extensionPointName, metadata)](/doc/en/lb4/apidocs.core.extensions.list.html) | Inject an array of resolved extension instances for the extension point. The list is a snapshot of registered extensions when the injection is fulfilled. Extensions added or removed afterward won't impact the list. |
| [view(extensionPointName, metadata)](/doc/en/lb4/apidocs.core.extensions.view.html) | Inject a `ContextView` for extensions of the extension point. The view can then be listened on events such as `bind`, `unbind`, or `refresh` to react on changes of extensions. |
