3. 11.x core/lib/Drupal/Core/Menu/DefaultMenuLinkTreeManipulators.php \Drupal\Core\Menu\DefaultMenuLinkTreeManipulators::checkNodeAccess()

Performs access checking for nodes in an optimized way.

This manipulator should be added before the generic ::checkAccess() one, because it provides a performance optimization for ::checkAccess().

Parameters

\Drupal\Core\Menu\MenuLinkTreeElement[] $tree: The menu link tree to manipulate.

Return value

\Drupal\Core\Menu\MenuLinkTreeElement[] The manipulated menu link tree.

File

Provides a couple of menu link tree manipulators.

Namespace

Drupal\Core\Menu

Code

public function checkNodeAccess(array $tree) {
    $node_links = [];

        // query rewrite as well as not checking for the node status. The
        // 'view own unpublished nodes' permission is ignored to not require cache
        // entries per user.
