基本枚举类继承

2021-12-29 00:00:00 enums c++

是否有一种模式可以让我从 C++ 中的另一个枚举继承枚举??

Is there a pattern where I can inherit enum from another enum in C++??

类似的东西:

enum eBase 
{
   one=1, two, three
};


enum eDerived: public eBase
{
   four=4, five, six
};

推荐答案

不可能.枚举没有继承.

Not possible. There is no inheritance with enums.

您可以改为使用具有命名 const int 的类.

You can instead use classes with named const ints.

示例:

class Colors
{
public:
  static const int RED = 1;
  static const int GREEN = 2;
};

class RGB : public Colors
{
  static const int BLUE = 10;
};


class FourColors : public Colors
{
public:
  static const int ORANGE = 100;
  static const int PURPLE = 101;
};
