Re: Multiple operator overloading

I then had another idea, create the template class that returns to the
correct type, and then specialize it correctly.

--8<---------------cut here---------------start------------->8---

template<typename T>
class Attribute
{
protected:
    string value;
public:
    void setValue(string& _value) { value = _value; }
    virtual T fromString(const string&) = 0;
};

class IntAttr : public Attribute<int>
{
public:
    int fromString(const string& value) {
        return atoi(value.c_str());
    }
};

class Globals
{
private:
    ConfigParser parser;
    // maybe the key should be (char *) instead
    std::map<string, Attribute> config;
    
public:
    Globals();
    Attribute& operator[](const string& idx) { return config[idx]; }
};

I thought it was working but of course there's a problem, since
"Attribute" it's not a type, so I can't make the generic map...
Looks like I'm in an empasse and there's no way to do what I wanted,
it's really a pity though.
