constant ConfigEvents::DELETE

Name of the event fired when deleting a configuration object.

This event allows modules to perform an action whenever a configuration object is deleted. The event listener method receives a \Drupal\Core\Config\ConfigCrudEvent instance.

See hook_update_N() documentation for safe configuration API usage and restrictions as this event will be fired when configuration is deleted by hook_update_N().
