Class

Server

Defines the search server configuration entity.

Namespace

Drupal\search_api\Entity

Code

public static function preDelete(EntityStorageInterface $storage, array $entities) {

  // @todo This will, via Index::onDependencyRemoval(), remove all indexes
  //   from this server, triggering the server's removeIndex() method. This
  //   is, at best, wasted performance and could at worst lead to a bug if
  //   removeIndex() saves the server. We should try what happens when this is
  //   the case, whether there really is a bug, and try to fix it somehow –
  //   maybe clever detection of this case in removeIndex() or
  //   Index::postSave(). $server->isUninstalling() might help?
  parent::preDelete($storage, $entities);

  // Iterate through the servers, executing the backends' preDelete() methods
  // and removing all their pending server tasks.
  foreach ($entities as $server) {

    /** @var \Drupal\search_api\ServerInterface $server */
    if ($server
      ->hasValidBackend()) {
      $server
        ->getBackend()
        ->preDelete();
    }
    \Drupal::getContainer()
      ->get('search_api.server_task_manager')
      ->delete($server);
