An abstract class is a class that is designed to be specifically used as a base class. An abstract class contains at least one pure virtual function. You declare a pure virtual function by using a pure specifier (= 0) in the declaration of a virtual member function in the class declaratio...
it is not a good idea tooverrideandoverwritea method at the same time. Your Initialize method of newFoo does so. So you will have to make the base class Initialize method non abstract or to implement it in the newFoo class.
With the following codes, I got an intellisense error of "object of abstract class type is not allowed" at "new newFoo();" line. #include "stdafx.h" #include <Windows.h> class foo { public: static HRESULT get_Id(WCHAR** get_IdResult); virtual HRESULT Initialize() abstract; }; cl...
C++ 在 cocos2d-x中,报错:allocating an object of abstract class type “xxxx” 通常是该类,有未实现的虚函数,需要实现。
C/C++ allocating an object of abstract class type 原因:一般是因为该类继承的抽象类中,有未实现的抽象函数。在实例化的时候: (a)一定要确保父类所有的纯虚函数都要被实现,否则子类依然不能被实例化; (b)一定要确保继承的虚函数确保函数的入参类型,返回值类

c++ 在cocos2d-x中,报错:Allocating an object of abstract class type“xxxxx” 1.在该类中,有未实现的虚函数,需要实现,或者是 父类里的虚函数子类没有实现造成的。 2.还有的情况是,在编写代码的过程中,虚函数在父类和子类中的函数名不一样,这
