Loads a menu link tree from the storage.

This function may be used build the data for a menu tree only, for example to further massage the data manually before further processing happens. MenuLinkTree::checkAccess() needs to be invoked afterwards.

The tree order is maintained using an optimized algorithm, for example by storing each parent in an individual field. However, any details of the storage should not be relied upon since it may be swapped with a different implementation.

Parameters

string $menu_name: The name of the menu.

\Drupal\Core\Menu\MenuTreeParameters $parameters: The parameters to determine which menu links to be loaded into a tree.

Return value

array An array with 2 elements:

• tree: A fully built menu tree containing an array. @see static::treeDataRecursive()
• route_names: An array of all route names used in the tree.
