在 ZF2 中初始化水化器结果集和聚合

Question

我正在加入两个表并成功编写了一个输出以下数组的水化器：

    $sql = new Sql($this->dbAdapter);
    $select = $sql->select('misc_damage');
    $select->where(array('vehicle_id = ?' => $id))->order('date_added DESC');
    $select->join('user','user.user_id = misc_damage.added_user_id', 
            array(
                'user_display_name' => 'display_name', 
                'user_email' => 'email',
                'user_username' => 'username'
                ), 
    'left');

    $stmt = $sql->prepareStatementForSqlObject($select);
    $result = $stmt->execute();

    if ($result instanceof ResultInterface && $result->isQueryResult()) {

        $hydrator = new AggregateHydrator();
        $hydrator->add(new ClassMethods());
        $hydrator->add(new \Application\Hydrator\UserHydrator());

        $miscDamage = $hydrator->hydrate($result->current(), new \Application\Model\Miscdamage());
        var_dump($miscDamage);
        die();
    }

这会产生 1 个结果：

/var/www/zf-skeleton/module/Application/src/Application/Mapper/ZendDbSqlMapper.php:95:
object(Application\Model\Miscdamage)[655]
  protected 'id' => string '97' (length=2)
  protected 'vehicle_id' => string '3' (length=1)
  protected 'added_user_id' => string '1' (length=1)
  protected 'description' => string 'sdfsdsdf' (length=8)
  protected 'date_added' => string '2016-04-15 08:19:17' (length=19)
  protected 'date_repaired' => null
  protected 'repaired_user_id' => null
  protected 'status' => string '0' (length=1)
  protected 'user' => 
    object(Application\Model\User)[664]
      protected 'user_id' => string '1' (length=1)
      protected 'username' => null
      protected 'email' => string 'alex@home.com' (length=13)
      protected 'display_name' => string 'Alex' (length=4)

应该有多个结果，因为每辆车可以有多个损坏条目。我将如何使用 HydratingResultSet 和我的 AggregateHydrator？我也想初始化结果：return $resultSet->initialize($result);

感谢任何帮助！

我知道怎么做了。需要使用 HydratingResultSet 和 Reflection:

    use Zend\Stdlib\Hydrator\Reflection as ReflectionHydrator;    

    if ($result instanceof ResultInterface && $result->isQueryResult()) {

        $hydrator = new AggregateHydrator();
        $hydrator->add(new ClassMethods());
        $hydrator->add(new \Application\Hydrator\UserHydrator());

        $resultSet  = new HydratingResultSet(new ReflectionHydrator, new \Application\Model\Miscdamage());
        $resultSet->setHydrator($hydrator);

        return $resultSet->initialize($result);

    }
