public function MenuTreeStorageInterface::loadTreeData

public MenuTreeStorageInterface::loadTreeData($menu_name, MenuTreeParameters $parameters)

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, see https://www.drupal.org/node/141866 for more details. However, any details of the storage should not be relied upon since it may be swapped with a different implementation.

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

Return value
