public ApcuBackend::garbageCollection() Performs garbage collection on a cache bin. The backend may choose to delete expired or invalidated items. Overrides CacheBackendInterface::garbageCollection File core/lib/Drupal/Core/Cache/ApcuBackend.php, line 213 Class ApcuBackend Stores cache items in the Alternative PHP Cache User Cache (APCu). Namespace Drupal\Core\Cache Code public function garbageCollection() { // APCu performs garbage collection automatically. }

public ApcuBackend::deleteMultiple(array $cids) 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::delete

public ApcuBackend::deleteAll() Deletes all cache items in a bin.
