将元组成员包装在其他模板类型中

Question

我希望能够使用模板包声明一个类,这样类本身将有一个成员变量元组,它将每个模板包成员包装在某种容器类型中.基本目标如下:

template <typename Types...>
class VectorOfMembers 
{
public:
    // Member tuple where each element is expanded in a container
    std::tuple<std::vector<Type[1]>, std::vector<Type[2]>, std::vector<TypeN...>>
};

理想情况下,我希望能够将任何模板化对象作为包装类型.

好吧,你几乎拥有它:

template <typename... Types>
class VectorOfMembers
{
public:
    // Member tuple where each element is expanded in a container
    std::tuple<std::vector<Types>...> tuple;
};
