Question

您好，我希望将对象向量声明为另一个类的成员，但我不太清楚如何执行此操作。我也在最后一个函数中正确填充向量吗？

这是我要创建

矢量的类

class AggregatedQuoteType
{
    public:
        AggregatedQuoteType(double price, unsigned long volume);
        double get_price() const;
        unsigned long get_volume() const;
        unsigned long get_number_of_orders() const;
    private:
        double newPrice;
        unsigned long newVolume;
};

我希望矢量成为这个类的成员

class OrderBook
{
    public:

        OrderBook ();

        void open (double tick_size, double tolerance, std::ostream &log);

        void close ();

        unsigned long submit_order (double price, unsigned long volume);

    private:

        PriceType order_tick_size;

        PriceType order_tolerance;


};

这是我迄今为止的功能

unsigned long OrderBook::submit_order (double price, unsigned long volume)
{
    AggregatedQuoteType newQuote(price, volume);
    unsigned long number_of_orders = newQuote.get_number_of_orders();
    std::vector<AggregatedQuoteType> newMyOrder;

    if(price > 0 && volume > 0){
        for (unsigned int i = 0; i < number_of_orders; i++){
            newMyOrder.push_back(newQuote);
        }
    }

    return 0u;
}

任何帮助都会有用。

如果没有完全理解submit_order（）的工作原理，我认为你需要这样的东西：

   class OrderBook
    {
        public:
            OrderBook ();
            void open (double tick_size, double tolerance, std::ostream &log);
            void close ();
            unsigned long submit_order (double price, unsigned long volume);   
        private:
            PriceType order_tick_size;
            PriceType order_tolerance;
            std::vector<AggregatedQuoteType> quotes_;  
    };


unsigned long OrderBook::submit_order (double price, unsigned long volume)
{
    AggregatedQuoteType newQuote(price, volume);
    unsigned long number_of_orders = newQuote.get_number_of_orders();

    if(price > 0 && volume > 0){
        for (unsigned int i = 0; i < number_of_orders; i++){
            quotes_.push_back(newQuote);
        }
    }
    return 0u;
}
