我知道之前已经问过这个问题,我尝试过发布的解决方案,但由于某种原因,我仍然无法解决我所面临的问题。
我正在尝试创建派生类的对象。但是,我收到一条错误消息:
Error: no instance of constructor "CALibrary::YieldCurve::YieldCurve" matches te argument list argument types are: (std::string, std::vector<std::pair<double,double>,double>)
父类是:
namespace CALibrary {
class YieldCurveIF {
public:
virtual double getDiscountFactor(double fromDate, double toDate) = 0;
int getSize() {
return _curve.size();
}
std::vector<std::pair<double, double>> getCurve() {
return _curve;
}
void setParameters(std::string curveName,
std::vector<std::pair<double, double>>& curve)
{
_curveName = curveName;
_curve = curve;
}
protected:
std::string _curveName;
std::vector<std::pair<double, double>> _curve;
};
}
派生类是:
namespace CALibrary {
class YieldCurve : public CALibrary::YieldCurveIF
{
public:
YieldCurve(std::string curveName,
std::vector<std::pair<double, double>>& curve)
{
setParameters(curveName, curve);
}
double getDiscountFactor(double fromDate, double toDate);
private:
};
}
以下是我尝试创建YieldCurve对象的代码:
int nPayments = 4;
std::string curveName = "EURCurve";
std::vector<std::pair<double, double>, double> yCurve(nPayments);
CALibrary::YieldCurve _yieldCurve(curveName, yCurve);
答案 0 :(得分:0)
yCurve
有一个无意义的类型
std::vector<std::pair<double, double>, double>
删除最后的,double
。
此外,如果代码在两个地方占用std::vector<std::pair<double, double>>&
,则代码需std::vector<std::pair<double, double>> const&
。
