C++類型萃取編寫技巧，廢話不多說，上來貼代碼最實在，以下代碼量有點多,不過這都是在下一手一手敲出來的,小巧好用,把以下代碼復制出來,放到相應的hpp文件即可,VS,GCC下均能編譯通過
#include<iostream>
#include "../../traits/traits.hpp"
using namespace std;
int show(char i, int j)
{
return 1;
}
struct Stu
{
int show(char i, int j)
{
return 1;
}
};
int main()
{
// 變量;類型萃取
traits::type_traits<int>::const_value_type i = 5; // 通過traits::type_traits可以萃取到int類型的各種"衍生"類型,如指針什麼的
// 以下是C函數的相關萃取
traits::function_traits<int(char, int)>::FunctionP_Type func_ptr = show; // 得到指針
func_ptr('a', 4);
cout << traits::function_traits<int(char, int)>::arity << endl; // 萃取出參數個數
cout << typeid(traits::function_traits<int(char, int)>::arg2).name() << endl;//萃取出參數1的類型
cout << typeid(traits::function_traits<int(char, int)>::arg1).name() << endl;//萃取出參數2的類型
// 以下是類成員函數的相關萃取
traits::mfunction_traits<int(Stu::*)(char, int)>::MFunctionP_Type mfunc_ptr = &Stu::show; // 得到指針
Stu stu;
((&stu)->*mfunc_ptr)('a', 4);
cout << typeid(traits::mfunction_traits<int(Stu::*)(char, int)>::arg2).name() << endl;//萃取出參數1的類型
cout << typeid(traits::mfunction_traits<int(Stu::*)(char, int)>::arg1).name() << endl;//萃取出參數2的類型
cout << typeid(traits::mfunction_traits<int(Stu::*)(char, int)>::result_type).name() << endl;//萃取出返回值
cout << typeid(traits::mfunction_traits<int(Stu::*)(char, int)>::class_type).name() << endl;//萃取出類類型
// 以下展示從C函數指針轉為類成員函數指針的技巧
traits::fun_to_mem_converter<int(char, int), Stu>::MFunctionP_Type mfunc_ptr2 = mfunc_ptr;
// 以下展示從類成員函數指針轉為C函數指針的技巧
traits::mem_to_fun_converter<int(Stu::*)(char, int)>::FunctionP_Type func_ptr2 = func_ptr;
return 0;
}
接下來是traits庫的完整代碼
