   * node access can use this method when doing mass updates due to widespread
   * permission changes.

   *
   * @param \Drupal\node\NodeInterface $node

   * @param array $grants
   *   A list of grants to write. Each grant is an array that must contain the
   *   following keys: realm, gid, grant_view, grant_update, grant_delete.
   *   The realm is specified by a particular module; the gid is as well, and
   *   is a module-defined id to define grant privileges. each grant_* field
   *   is a boolean value.
   * @param string $realm
   *   (optional) If provided, read/write grants for that realm only. Defaults to
   *   NULL.
   * @param bool $delete
   *   (optional) If false, does not delete records. This is only for optimization
   *   purposes, and assumes the caller has already performed a mass delete of
   *   some form. Defaults to TRUE.
