protected function EntityAccessChecker::checkRevisionViewAccess in Drupal 8

Same name and namespace in other branches

9 core/modules/jsonapi/src/Access/EntityAccessChecker.php \Drupal\jsonapi\Access\EntityAccessChecker::checkRevisionViewAccess()
10 core/modules/jsonapi/src/Access/EntityAccessChecker.php \Drupal\jsonapi\Access\EntityAccessChecker::checkRevisionViewAccess()

Checks access to the given revision entity.

This should only be called for non-default revisions.

There is no standardized API for revision access checking in Drupal core and this method shims that missing API.

@todo: remove when a generic revision access API exists in Drupal core, and also remove the injected "node" and "media" services.

Parameters

\Drupal\Core\Entity\EntityInterface $entity: The revised entity for which to check access.

\Drupal\Core\Session\AccountInterface $account: (optional) The account with which access should be checked. Defaults to the current user.

Return value

\Drupal\Core\Access\AccessResultInterface|\Drupal\Core\Access\AccessResultReasonInterface The access check result.

File

core/modules/jsonapi/src/Access/EntityAccessChecker.php, line 243
