CRTP和赋值运算符

Question

我有一些代码分配给这样的CRTP类：

        IChunkWindow<WindowDerived, IChunk<ChunkDerived>> editWindow = chunkWindow.create(
                                                                chunkWindow.getOrigin().getX() + x / ChunkDimensions::MAX_X,
                                                                chunkWindow.getOrigin().getZ() + z / ChunkDimensions::MAX_Z,
                                                                chunkWindow);

这是CRTP类：

    template <class Derived, class T>
struct IChunkWindow : public IWindow<IChunkWindow<Derived,T>, T> {

    Point3D const& getOrigin() const {
        return static_cast<Derived const*>(this)->getOrigin();
    }

    void setOrigin(Point3D const& origin) {
        this->origin = origin;
        static_cast<Derived*>(this)->setOrigin(origin);
    }
    T* getChunk(int cx, int cz) {
        return static_cast<Derived*>(this)->getChunk(cx,cz);
    }
    void setChunk(int cx, int cz, T* ptr) {
        static_cast<Derived*>(this)->setChunk(cx,cz,ptr);
    }

    unsigned char getTerrainBlock(int x, int y, int z) const {
        return static_cast<Derived const*>(this)->getTerrainBlock(x,y,z);
    }
    void setTerrainBlock(int x, int y, int z, unsigned char value) {
        static_cast<Derived*>(this)->setTerrainBlock(x,y,z,value);
    }
    unsigned char getLightBlock(int x, int y, int z) const {
        return static_cast<Derived const*>(this)->getLightBlock(x,y,z);
    }
    void setLightBlock(int x, int y, int z, unsigned char value) {
        static_cast<Derived*>(this)->setLightBlock(x,y,z,value);
    }
    unsigned char getMetaBlock(int x, int y, int z) const {
        return static_cast<Derived const*>(this)->getMetaBlock(x,y,z);
    }
    void setMetaBlock(int x, int y, int z, unsigned char value) {
        static_cast<Derived*>(this)->setMetaBlock(x,y,z,value);
    }
    bool isChunkDirty(int cx, int cz) {
        return static_cast<Derived*>(this)->isChunkDirty(cx,cz);
    }
    bool inBounds(int x, int y, int z) {
        return static_cast<Derived*>(this)->inBounds(x,y,z);
    }
    bool inBounds(int a_cx, int a_cz) {
        return static_cast<Derived*>(this)->inBounds(a_cx, a_cz);
    }
    void insert(int a_x, int a_y, int a_z, unsigned char blockType) {
        static_cast<Derived*>(this)->insert(a_x,a_y,a_z,blockType);
    }
    void remove(int a_x, int a_y, int a_z) {
        static_cast<Derived*>(this)->remove(a_x, a_y, a_z);
    }
    std::vector<BlockPosition> waterPhysics(int a_x, int a_y, int a_z, std::vector<BlockPosition> const& waterSources) {
        static_cast<Derived*>(this)->waterPhysics(a_x,a_y,a_z, waterSources);
    }

    IChunkWindow<Derived, T> create(int a_cx, int a_cz, IChunkWindow<Derived, T> & otherWindow) {
        return static_cast<Derived*>(this)->create(a_cx, a_cz, otherWindow);
    }

};

我可以在editWindow上进行方法调用，但是基类的私有数据（未显示）是垃圾，所以看起来分配失败了。我是否需要覆盖IChunkWindow类中的赋值运算符才能使其生效？
