Question

I’m looking for a way to use std::set::const_iterator as const_iterator of my own class.

My code (which actually behaves correct and compiles fine), goes like:

class MyClass{

public:
    typedef std::set<T>::const_iterator const_iterator;

const_iterator begin() const {
    return mySet->begin();
}

const_iterator end() const {
    return mySet->end();
}

}; // MyClass

So, my question is: Is my way of using the const_iterator acceptable and also in the STL intended form?

Edit: Related question and answers at How to typedef the iterator of a nested container?

Answer 1

Have a look at other C++ Standard Library container adapters like std::queue. std::queue is just an adapter on top of an underlying container (by default a std::deque).

This is exactly the method used in those adapters. Given that, I would say your implementation is fine.
