把DECLARE_DYNAMIC宏加入类的头文件中,然后在全部需要访问词类对象的.CPP文件中都包含此模块。如果像所描述那样使用DELCARE_DYNAMIC和IMPLEMENT_DYNAMIC宏,那么用户便可使用RUNTIME_CLASS宏和CObject::IsKindOf函数以在运行时间决定对象类。如果DECLARE_DYNAMIC包含在类定义中,那么IMPLEMETN_DYNAMIC必须包含在...
RUNTIME_CLASS为class_name指定的类返回一个指向CRuntimeClass结构的指针。只有用DECLARE_DYNAMIC,DECLARE_DYNCREATE或DECLARE_SERIAL定义的CObject的派生类才能返回CRuntimeClass结构指针。更多的信息参见“Visual C++程序员指南”中的“CObject类”主题。 【示例】 // RUNTIME_CLASS的例子 CRuntimeClass* prt =RUNTIM...

在类定义内部加上DECLARE_SERIAL(你的类名),不需要引号,如 class CMyClass: public CObject { public: CMyClass( ); void Serialize( CArchive& archive ); DECLARE_SERIAL( CmyClass ) }; 在类的实现文件开始加上IMPLEMENT_SERIAL(),如: /* MyClass.cpp */ #include "stdafx.h" #include "MyClass.h...
class Animal { name; } global_type.Animal = Animal; })(global_type || (global_type = {})); const myObject = new global_type.Animal(); 1. 2. 3. 4. 5. 6. 7. 8. 可以看到,代码中使用iife产生了一个私有的作用域并且定义了一个空对象,将命名空间导出的变量放至对象中。
