[ROOT] Operator overloading [silly question]

Hi Rooters,

Just a simple question.  I'm still learning so I'm sorry if this is one
of those "What's an int?" questions.  I have a class the inherits from
TMap and I want to emulate associative arrays.  

I have this:

    TString operator[](const char* key)
    {
        TObjString *tosKey = new TObjString(key);
        TString value;
       
        if( this->TMap::GetValue(tosKey) )
            value = ((TObjString
*)(this->TMap::GetValue(tosKey)))->String();
       
        delete tosKey;
       
        return value;
    }
root [1] THTTPData td;                                         
root [2] td.Add(new TObjString("bob"), new TObjString("smith"));
root [3] cout << td["bob"] << endl;                            
smith
root [4]

which works fine, but I'd like to also be able to do

td["jane"] = "anderson";

Is it possible?  (add another operator overload? but then how does C++
tell the difference between the two)

Thanks for your patience :-)
