Question

我有一个自定义容器UniqueArray。这是头文件：

using namespace std;
template <class Element, class Compare = std::equal_to<Element>>
class UniqueArray {

public:
    Element** data;
    unsigned int curr_size;
    unsigned int max_size;
    int* availability_array;

    explicit UniqueArray(unsigned int size);
    UniqueArray(const UniqueArray& other);
    ~UniqueArray();
    UniqueArray& operator=(const UniqueArray&) = delete;
    unsigned int insert(const Element& element);
    bool getIndex(const Element& element, unsigned int& index) const;
    const Element* operator[] (const Element& element) const;
    bool remove(const Element& element);
    unsigned int getCount() const;
    unsigned int getSize() const;

    class Filter {
    public:
        virtual bool operator() (const Element&) const = 0;
    };
    UniqueArray filter(const Filter& f) const;

    class UniqueArrayIsFullException{};

    typedef Element** ua_iterator;
    typedef const Element** ua_const_iterator;

    ua_iterator begin(){
        return data;
    }
    ua_const_iterator begin() const {
        return data;
    }
    ua_iterator end(){
        return data + max_size;
    }
    ua_const_iterator end() const {
        return data + max_size;
    }
};

现在，此容器稍后在称为ParkingLot的较大容器中使用，这是头文件：

using namespace ParkingLotUtils;
using std::ostream;

namespace MtmParkingLot {


    class ParkingLot {
    public:

        UniqueArray<Vehicle, Vehicle::compareVehicles> motorbike_parking;
        UniqueArray<Vehicle, Vehicle::compareVehicles> car_parking;
        UniqueArray<Vehicle, Vehicle::compareVehicles> handicapped_parking;

        ParkingLot(unsigned int parkingBlockSizes[]);
        ~ParkingLot() = default;
        ParkingResult enterParking(VehicleType vehicleType, LicensePlate licensePlate, Time entranceTime);
        ParkingResult exitParking(LicensePlate licensePlate, Time exitTime);
        ParkingResult getParkingSpot(LicensePlate licensePlate, ParkingSpot& parkingSpot) const;
        void inspectParkingLot(Time inspectionTime);
        friend ostream& operator<<(ostream& os, const ParkingLot& parkingLot);
        int calculateFee(Time entryTime, Time exitTime, VehicleType type);
        int calculateFeeRecursive(Time entryTime, Time exitTime, VehicleType type, int iter, int totalPrice);
        bool isVehicleInLot(LicensePlate licensePlate, VehicleType& type, unsigned int& index);
    };
}

我非常想尝试遍历整个ParkingLot。到目前为止，这是我写的内容，不确定如何继续：

    void ParkingLot::inspectParkingLot(Time inspectionTime) {
        std::vector<UniqueArray<Vehicle, Vehicle::compareVehicles>> ParkingLotVector = {motorbike_parking, car_parking, handicapped_parking};
        std::vector<UniqueArray<Vehicle, Vehicle::compareVehicles>>::iterator ParkingLotIterator;
        for(ParkingLotIterator = ParkingLotVector.begin(); ParkingLotIterator < ParkingLotVector.end(); ParkingLotIterator++){
            for(/*stuck*/)
        }
    }

在第一个for循环中，通过向量内部的UniqueArrays进行迭代。如何使用我在第一个头文件中声明的迭代器在每个Element中的UniqueArrays中进行迭代？
