Are several overloaded operator[] possible?

[rgeddes]

Hi

I've created a class with a single vector as a private member, and overloaded operator[] to get/set the nth vector element at [n]... no problem.

I now have a need to add more vectors to the same class.

Is there an easy way to overload operator[] to get/set elements from/for the different vectors that are members of the same class?

like
reference operator[]1(int); // to access the first vector
reference operator[]2(int); // to access the second vector
etc.

Thanks
Richard

Since that operator only takes one parameter, the only way to overload it would be use different parameter types.
It looks that the best approach would be a regular member function with two parameters, though.

Yes, it is possible, but it is usually not worth the trouble and/or a bad idea.

Instead of overloading [], overload ().

You can check out sections 13.10..12 of the C++ FAQ Lite for more info.

Hope this helps.
