3. 11.x core/modules/block_content/src/BlockContentAccessControlHandler.php \Drupal\block_content\BlockContentAccessControlHandler::checkAccess()

Performs access checks.

This method is supposed to be overwritten by extending classes that do their own custom access checking.

Parameters

\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.
