public function MemoryBackend::deleteMultiple in Drupal 9

Same name and namespace in other branches

1. 8 core/lib/Drupal/Core/Cache/MemoryBackend.php \Drupal\Core\Cache\MemoryBackend::deleteMultiple()

Deletes multiple items from the cache.

If the cache items are being deleted because they are no longer "fresh", you may consider using invalidateMultiple() instead. This allows callers to retrieve the invalid items 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

array $cids: An array of cache IDs to delete.

Overrides CacheBackendInterface::deleteMultiple
