shared_ptr const problem

27 Aug 2002

      Hi,

now I have a new problem - const correctness.

---8<---
#include <iostream>
#include <algorithm>
#include <iterator>
#include <vector>

#include <boost/shared_ptr.hpp>

class Doc 
{
public:
  virtual ~Doc() { }

public:
 const std::vector<double>& foo() const { return m_foo; }

protected:
  std::vector<double>& foo() { return m_foo; }

private:
  std::vector<double>           m_foo;
};

using namespace std;

int main()
{
  boost::shared_ptr<Doc> lp_doc( new Doc );

  std::copy(lp_doc->foo().begin(), lp_doc->foo().end(),
            std::ostream_iterator<double>(cout, " ") );
  cout << endl;
}
--->8---

`std::vector<double, std::allocator<double> >& Doc::foo()' is protected

I hoped std::copy takes the const foo() member function.

Thanks
