Iterator for custom container with derived classes

Question

I\'ve a custom container which is implemented in two different ways, but with a single interface. some thing like this.

    class Vector 
    {
       virtua         


        

Answer 1

A possibility is to use a template class for your container, with the private data-container as parameter. This way, the iterator can be defined in the class independent of the data-container.
I'm just not sure whether this is "unified" enough for what you need.
