reverse_iterator的封装

[Qlaiaqu]

各位好，目前我在写一个容器，其中为了能够兼容stl里面的一些东西，于是封装了自己的iterator代码，如下：

//cyclequeue的迭代器
template<class _Tp, class _Ref, class _Ptr>
struct CCycleQueue_iterator
{
    typedef random_access_iterator_tag iterator_category;
    typedef _Tp value_type;
    typedef ptrdiff_t                  difference_type;
    typedef _Ptr pointer;
    typedef _Ref reference;

    typedef CCycleQueue_iterator<_Tp,_Tp&,_Tp*>             iterator;
    typedef CCycleQueue_iterator<_Tp,const _Tp&,const _Tp*> const_iterator;
    typedef CCycleQueue_iterator<_Tp,_Ref,_Ptr>             _Self;
    typedef size_t                     size_type;
    typedef CCycleQueue<_Tp> _Cyclequeue;

    _Cyclequeue* m_pCycleQueue;
    size_type m_unPos;

    CCycleQueue_iterator(_Cyclequeue* x, size_type __pos) : m_pCycleQueue(x),m_unPos(__pos) {}
    CCycleQueue_iterator() {}
    CCycleQueue_iterator(const iterator& x):m_pCycleQueue(x.m_pCycleQueue),m_unPos(x.m_unPos) {}

    reference operator*() const
    {
        return (*m_pCycleQueue)[m_unPos];
    }

    pointer operator->() const
    {
        return &(operator*());
    }

    bool operator==(const CCycleQueue_iterator& x) const
    {
        return ((m_pCycleQueue == x.m_pCycleQueue) && (m_unPos == x.m_unPos));
    }

    bool operator!=(const CCycleQueue_iterator& x) const
    {
        return ((m_pCycleQueue != x.m_pCycleQueue) || (m_unPos != x.m_unPos));
    }

    _Self& operator++()
    {
        m_unPos++;
        return *this;
    }

     _Self& operator+(const size_type& __size)
    {
        m_unPos += __size;
        return *this;
    }

    _Self operator++(int)
    {
        _Self __tmp = *this;
        m_unPos++;
        return __tmp;
    }
    _Self& operator--()
    {
        m_unPos--;
        return *this;
    }
    _Self operator--(int)
    {
        _Self __tmp = *this;
        m_unPos--;
        return __tmp;
    }
};

我在容器类中使用反向迭代器的时候的时候，出现该错误，不知何解，还请高手请教：

template <typename _Tp>
class CCycleQueue
{
public:
    typedef _Tp value_type;
    typedef value_type* pointer;
    typedef const value_type* const_pointer;
    typedef CCycleQueue_iterator<_Tp, _Tp&, _Tp*> iterator;
    typedef const CCycleQueue_iterator<_Tp, const _Tp&, const _Tp*> const_iterator;
    typedef reverse_iterator<const_iterator> const_reverse_iterator;
    typedef reverse_iterator<iterator>       reverse_iterator;
    typedef value_type& reference;
    typedef const value_type& const_reference;
    typedef size_t size_type;


使用函数：
 inline reverse_iterator rbegin()
    {
        return  reverse_iterator(end());
    }

    inline reverse_iterator rend()
    {
        return reverse_iterator(begin());
    }

错误：

D:\project\Test\cyclequeue.h|97|error: declaration of 'typedef class std::reverse_iterator<CCycleQueue_iterator<_Tp, _Tp&, _Tp*> > CCycleQueue<_Tp>::reverse_iterator'|
