c++11中的可变参数模板

记录一下怕忘记!

#include <iostream>

class MyClass
{
public:
static void fun()
{
std::cout << "hello world!" << std::endl;
}
};

template<class T0, class... T>
struct Class;

template<class T0>
class Class<T0>
{
public:
void runInit()
{
T0::fun();
}
};

template<class T0, class T1, class... T>
class Class<T0, T1, T...> : public Class<T0, T...>
{
public:
void runInit()
{
T1::fun();
}
};

template<class T0, class T1, class T2, class... T>
class Class<T0, T1, T2, T...> : public Class<T0, T1, T...>
{
public:
void runInit()
{
T2::fun();
}
};

int main()
{
Class<MyClass, MyClass, MyClass> c;
c.runInit();
return 0;
}
vistual studio 2013中编译通过
结果如下:

  hello world!
