How to use Iterator Adaptors?

Hi,

I'm struggling to understand how to use Iterator Adaptors, due to a 
lack of simple examples.  This is disappointing, given that 
supposedly "Using iterator_adaptor, you can easily implement an  
iterator class" (www.boost.org/libs/utility/iterator_adaptors.htm).  
Can anyone help, by explaining how to implement a random access 
iterator for a custom collection class?  e.g.:

    template <class T> class DumbCollection
    {
    public:
        DumbCollection(T data[10])
            { for (int i = 0; i < 10; i++) m_data[i] = data[i]; }
        iterator begin();
        iterator end();
    private:
        T    m_data[10];
    };

Thanks, Keith
