如何在不暴露使用的容器的情况下暴露迭代器?

I would like to expose an iterator for a class like this:

template <class T>
class MyContainer
{
public:
    // Here is the problem:
    // typedef for MyIterator without exposing std::vector publicly?

    MyIterator Begin() { return mHiddenContainerImpl.begin(); }
    MyIterator End() { return mHiddenContainerImpl.end(); }

private:
    std::vector<T> mHiddenContainerImpl;
};

我是否正在尝试一些不成问题的事情?我应该只是 typedef std::vector<T >::迭代器?我希望只依赖于迭代器，而不是实现容器......
