Question

是否可以自动生成这样的内容？我只想要特定成员一次并生成三个类（它们相似但是......）

class recipe{
public:
  int timeToPrepare;
  std::string name;
}

class recipeQuery{
public:
  baseQuery<int> timeToPrepare;
  baseQuery<std::string> name;
}


class recipeScheme{
public:
  schemeItem<int> timeToPrepare;
  schemeItem<std::string> name;
}

Answer 1

这样的东西？

template <class T1 = int, class T2 = std::string> class recipe {
    T1 timeToPrepare;
    T2 name;
};

typedef recipe< baseQuery<int>, baseQuery<std::string> > recipeQuery;

typedef recipe< schemeItem<int>, schemeItem<std::string> > recipeQuery;

Answer 2

template<template<typename> class T>
class recipe{
public:
    T<int> timeToPrepare;
    T<std::string> name;
};

typedef recipe<baseQuery> recipeQuery;
typedef recipe<schemeItem> recipeScheme;

C ++类，具有不同类型的相同成员
