这使得工厂方法模式可以允许系统在不修改工厂角色的情况下引进新产品。 在Factory Method模式中,工厂类与产品类往往具有平行的等级结构,它们之间一一对应。 二、 Factory Method模式角色与结构: 抽象工厂(Creator)角色:是工厂方法模式的核心,与应用程序无关。任何在模式中创建的对象的工厂类必须实现这个接口。 具体工厂(...
Assembly.Load("FactoryMethodExample").CreateInstance( "FactoryMethodExample." + gameSceneName + "Factory"); } public void LoadScene( string gameSceneName) { PatrixSceneFactory psf = GetGameScene(gameSceneName); PatrixScene ps = psf.CreateScene(); ps.InitScene(); } } abstract class Patrix...
这就是Factory的雏形。Factroy要解决的问题是：希望能够创建一个对象，但创建过程比较复杂，希望对外隐藏这...

TheIsClassIDmethod determines whether a CLSID matches this class template. Syntax C++Copy BOOLIsClassID( REFCLSID rclsid ); Parameters rclsid Reference to a CLSID. Return value ReturnsTRUEif therclsidparameter is the same CLSID as theCFactoryTemplate::m_ClsIDmember variable, or else returnsFALSE...
定义一个用于创建对象的接口,让子类决定实例化哪一个类。Factory Method使一个类的实例化延迟到其子类。 2.别名 虚构造器(Virtual Constructor) 3.动机 框架使用抽象类定义和维护对象之间的关系。这些对象的创建通常也由框架负责。 考虑这样一个应用框架,它可以向用户显示多个文档。在这个框架中,两个主要的抽象是类...
