Provides a couple of menu link tree manipulators.

This class provides menu link tree manipulators to:

  • perform render cached menu-optimized access checking
  • optimized node access checking
  • generate a unique index for the elements in a tree and sorting by it
  • flatten a tree (i.e. a 1-dimensional tree)

  /**
   * Performs access checks of a menu tree.
   *
   * Sets the 'access' property to AccessResultInterface objects on menu link
   * tree elements. Descends into subtrees if the root of the subtree is
   * accessible. Inaccessible subtrees are deleted, except the top-level
   * inaccessible link, to be compatible with render caching.
   *
   * (This means that top-level inaccessible links are *not* removed; it is up
   * to the code doing something with the tree to exclude inaccessible links,
   * just like MenuLinkTree::build() does. This allows those things to specify
   * the necessary cacheability metadata.)
   *
   * This is compatible with render caching, because of cache context bubbling:
   * conditionally defined cache contexts (i.e. subtrees that are only
   * accessible to some users) will bubble just like they do for render arrays.
   * This is why inaccessible subtrees are deleted, except at the top-level
   * inaccessible link: if we didn't keep the first (depth-wise) inaccessible
   * link, we wouldn't be able to know which cache contexts would cause those
   * subtrees to become accessible again, thus forcing us to conclude that that
   * subtree is unconditionally inaccessible.
   *
   * @param \Drupal\Core\Menu\MenuLinkTreeElement[] $tree
   *   The menu link tree to manipulate.
   *
   * @return \Drupal\Core\Menu\MenuLinkTreeElement[]
   *   The manipulated menu link tree.
