[SOLVED] C++ using ranged for-loop inside container class

Jerry Mcguire · 06-05-2019, 09:27 AM

I can do this:

Code:

std::vector<Foo> vcfoo;
for ( const auto& n : vcfoo ) {
  n.print();
}

If the for-loop is in the member function of a class derived from the container class, how to do so?

Code:

class VecFoo : public std::vector<Foo>
{
  void print() const {
    for ( const auto& n : ??? ) {  // *this ? ugly
      n.print();
    }
  }
};

Thanks in advance.

It's fairly clear that *this is indeed what should be there.
