EnforcedResponse::createFromException

public static function EnforcedResponse::createFromException

public static EnforcedResponse::createFromException(\Exception $e)

Parameters

\Exception $e: The exception where the enforced response is to be extracted from.

Return value

\Drupal\Core\Form\EnforcedResponse|NULL The enforced response or NULL if the exception chain does not contain a \Drupal\Core\Form\EnforcedResponseException exception.
