我是模板新手,在使用它们时遇到了一些问题。我在下面发布了我无法编码的代码。在如何做这件作品方面需要帮助
我需要将函数指针作为模板参数传递给测试器类,并将 TClass 实例作为参数传递给构造函数。在构造函数中,函数指针将用于将 testFunc 绑定到测试器类的成员变量,该成员变量是函数指针。然后,当测试器类被销毁时,将调用 testFunc。无法解决模板的类型扣除
#include <iostream>
using namespace std;
template< class TClass, TClass::*fptr>
class tester
{
public:
tester(TClass & testObj, ...) //... refer to the arguments of the test function which is binded
{
//bind the function to member fptr variable
}
~tester()
{
//call the function which was binded here
}
private:
(TClass::*fp)(...) fp_t;
};
class Specimen
{
public:
int testFunc(int a, float b)
{
//do something
return 0;
}
}
int main()
{
typedef int (Specimen::*fptr)(int,float);
Specimen sObj;
{
tester<fptr> myTestObj(sObj, 10 , 1.1);
}
return 0
}
