protected QueryFactory::getKeys(Config $config, $key, $get_method, ConfigEntityTypeInterface $entity_type)
Creates lookup keys for configuration data.
Parameters
\Drupal\Core\Config\Config $config: The configuration object. @param 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.
