3. 11.x core/lib/Drupal/Core/Config/Entity/Query/QueryFactory.php \Drupal\Core\Config\Entity\Query\QueryFactory::getKeys()

Creates lookup keys for configuration data.

Parameters

\Drupal\Core\Config\Config $config: The configuration object.

string $key: The configuration key to look for.

string $get_method: Which method on the config object to call to get the value. Either 'get' or 'getOriginal'.

\Drupal\Core\Config\Entity\ConfigEntityTypeInterface $entity_type: The configuration entity type.

Return value

array An array of lookup keys concatenated to the configuration values.

Throws

\Drupal\Core\Config\Entity\Query\InvalidLookupKeyException The provided $key cannot end with a wildcard. This makes no sense since you cannot do fast lookups against this.
