  1. 10 core/lib/Drupal/Core/Config/ConfigCollectionEvents.php \Drupal\Core\Config\ConfigCollectionEvents

Defines events for working with configuration collections.

Configuration collections are often used to store configuration-related data, like overrides. The use case is determined by the module that provides the collection. A classic example is to store the translated parts of various configuration objects. Using a collection allows this data to be imported and exported alongside regular configuration. It also allows the data to be created when installing an extension. In both the import/export and extension installation situations, collection data is stored in subdirectories.
