  2. 9 core/lib/Drupal/Core/Update/UpdateBackend.php \Drupal\Core\Update\UpdateBackend::delete()

Deletes an item from the cache.

If the cache item is being deleted because it is no longer "fresh", you may consider using invalidate() instead. This allows callers to retrieve the invalid item by calling get() with $allow_invalid set to TRUE. In some cases an invalid item may be acceptable rather than having to rebuild the cache.

Parameters

string $cid: The cache ID to delete.

Overrides NullBackend::delete
