Concatenating C++ iterator ranges into a const vector member variable at construction time

Question

I have a class X, which I provide a snippet of here:

class X {
  public:
    template 
    X(Iter begin, Iter end) : mVec(begin, end) {}         


        

Answer 1

Your static method might not be as bad as you think, depending on the optimization your compiler does. And in C++0x, move constructors will remove any copying that is currently taking place.

In the meantime go with a wrapper iterator. The code is not likely to be as bad as the thread avakar links to, since you only need to implement an input iterator.
