protected function ApcuBackend::getAll in Zircon Profile 8
Same name and namespace in other branches
- 8.0 core/lib/Drupal/Core/Cache/ApcuBackend.php \Drupal\Core\Cache\ApcuBackend::getAll()
Returns all cached items, optionally limited by a cache ID prefix.
APCu is a memory cache, shared across all server processes. To prevent cache item clashes with other applications/installations, every cache item is prefixed with a unique string for this site. Therefore, functions like apc_clear_cache() cannot be used, and instead, a list of all cache items belonging to this application need to be retrieved through this method instead.
Parameters
string $prefix: (optional) A cache ID prefix to limit the result to.
Return value
\APCIterator An APCIterator containing matched items.
