Implementation

void deleteMany<T extends RealmObject>(Iterable<T> items) {
  if (items is RealmResults<T>) {
    _ensureManagedByThis(items, 'delete objects from Realm');

    realmCore.resultsDeleteAll(items);
  } else if (items is ManagedRealmList<T>) {
    _ensureManagedByThis(items, 'delete objects from Realm');

    realmCore.listDeleteAll(items);
  } else if (items is ManagedRealmSet<T>) {
    _ensureManagedByThis(items, 'delete objects from Realm');

    realmCore.realmSetRemoveAll(items);
  } else {
    for (T realmObject in items) {
      delete(realmObject);
    }
  }
