在以下情况下多态性似乎无法正常工作我有以下定义:interfaceBaseInterface{}interfaceNewInterface:BaseInterface{}classNewClass:NewInterface{}classGenericClasswhereT:BaseInterface{publicstringWhoIAm(TanObject){returnTestPolymorphism.CheckInterface(anObject);}}classImplementedClass:GenericClass{}classTestPolymorphism{publics

在C++中，假设我有一个实现接口(interface)类BaseInterface的类Derived，其中BaseInterface只有纯虚函数和一个虚析构函数:classBaseInterface{public:virtualvoiddoSomething()=0;~BaseInterface(){}};classDerived:publicBaseInterface{public:Derived(){}~Derived(){}protected:virtualvoiddoSomething();private:intx;};Derived类层次结构之外的任何类都不应直接调用Deri
