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

string $operation: The entity operation. Usually one of 'view', 'view label', 'update' or 'delete'.

\Drupal\Core\Session\AccountInterface $account: The user for which to check access.

Return value

\Drupal\Core\Access\AccessResultInterface The access result.

File

Class

BlockContentAccessControlHandler

Defines the access control handler for the custom block entity type.

Namespace

Drupal\block_content

Code

protected function checkAccess(EntityInterface $entity, $operation, AccountInterface $account) {
