Re: class with a map

Hi,

I would like to write a class storing http headers so Istarted with
this :

class WebHeaderCollection
{
private:
    std::map<tstring, tstring> m_KeyValueMap;

public:

    tstring& operator[](const tstring& Keyval)
    {
        tstring sTmp = Keyval + _T("\r\n");
        return m_KeyValueMap[ Keyval ];
    }
};

This class appends \r\n to each key entry.
My question is how can I give access to all the standard operations of
a map.
The simple solution would have been to derive from std::map but it
seems to be a bad idea to derive from STL containers.

So does it mean I need to provide an iterator, an overload operator
like I did, ...
