-/**
- * Metadata cache for a storage
- *
- * The cache stores the metadata for all files and folders in a storage and is kept up to date trough the following mechanisms:
- *
- * - Scanner: scans the storage and updates the cache where needed
- * - Watcher: checks for changes made to the filesystem outside of the ownCloud instance and rescans files and folder when a change is detected
- * - Updater: listens to changes made to the filesystem inside of the ownCloud instance and updates the cache where needed
- * - ChangePropagator: updates the mtime and etags of parent folders whenever a change to the cache is made to the cache by the updater
- *
- * @since 9.0.0
