使用c++11改写loki的TypeList(二)
typedef typename erase::type inner_result;
public:
typedef typename concat::type type;
};
template<>
struct no_duplicate< nulllist >
{
typedef nulllist type;
};
//////////////////////////////////////////////////////////
template struct replace;
template
struct replace >
{
typedef typename concat>::type>::type type;
};
template
struct replace >
{
typedef typename concat >::type type;
};
template
struct replace
{
typedef nulllist type;
};
//////////////////////////////////////////////////////////
template struct replace_all;
template
struct replace_all >
{
typedef typename concat>::type>::type type;
};
template
struct replace_all >
{
typedef typename concat>::type >::type type;
};
template
struct replace_all
{
typedef nulllist type;
};
//////////////////////////////////////////////////////////
template struct reverse;
template
struct reverse >
typedef typename concat>::type, T>::type type;
};
template<>
struct reverse< nulllist >
{
typedef nulllist type;
};
复制代码
例子：
复制代码
