(PrestaShop) 从核心类调用静态方法的正确方法

Question

核心文件之一 classes/stock/StockAvailable.php包含：

class StockAvailableCore extends ObjectModel

{

   public static function getQuantityAvailableByProduct($id_product = null, $id_product_attribute = null, $id_shop = null)

     {

       ...

     }

  ...

}

我想从我的模块中调用这个 getQuantityAvailableByProduct()方法。

所以我尝试包含这个类（它是父类和父类的接口），扩展它并像这样调用方法：

require_once('../../src/Core/Foundation/Database/EntityInterface.php');

require_once('../../classes/ObjectModel.php');

require_once('../../classes/stock/StockAvailable.php');

$MyClass = new StockAvailableCore();

$MyClass->getStockAvailableIdByProductId($id);

而我得到的错误：

PHP Fatal error:  Uncaught Error: Class 'ObjectModel' not found in /home/mantas/Server/honey/classes/stock/StockAvailable.php:34

我错过了什么？这是扩展类和调用方法的正确方法吗？
