Thread: Access enum class and its values outside of the class.

I cannot wrap my head as to how to access my enum class Azimuth.

Code:

#ifndef BOUSOLE_H
#define BOUSOLE_H

#include <iostream>
#include <string>
#include "StringHandler.h"

class Bousole{

    public:
        enum class Azimuth {NORD = 0,  //HOW TO ACCESS THESE
            EST = 90,
            SUD = 180,
            OUEST = 270,
            UNSET=-1};

        Bousole();
        Bousole(int deg);
        Bousole(Azimuth az);
        void setNord();
        void setEst();
        void setSud();
        void setOuest();
        void setAzimuth(int deg);
        void setAzimuth(Azimuth az);
        void display();
        Azimuth getAzimuth();
        std::string getPointcardinal();
        std::string toString();
        std::string toString(Azimuth az);

    private:
        int m_degre;
        Azimuth azimuth;
};

#endif

And here is where I am trying to access my enum for testing/understanding purposes

Code:

#include "Bousole.h"

using namespace std;

int main (int argc, char *argv[]){
    cout <<"Start bousole" << endl;
    Bousole b;
    Bousole::Azimuth az;  //Dont think this the way to go...
    b.display();

    cout << "Understand Azimuth ";
    cout <<az::NORD << endl;  //CONFUSED HERE 

    cout << "Setting Est...";
    b.setEst();
    b.display();

    return 0;
}

@Elysia.
I will have to double check this when I am at my computer, but I am pretty sure I tried Bousole::Azimuth::NORD or a combination thereof and got a compile error. Or I am lost... which is possible.
I was not very clear in what I try to do. In other words, I have a class Turtle (not shown here) which can move and change direction. To change direction it uses the class Bousole (Compas). So in my turtle, I want to be able to access the enum EAST, WEST, etc...

It turns out I get a compiler error when I do this:

Code:

cout << Bousole::Azimuth::OUEST << endl;

But I can do this without problem

Code:

 auto z=Bousole::Azimuth::OUEST;

But I cannot do cout << z without compile error. I guess I can work around this, but I was curious as to why it does not compile

@Elysia
It's a very interesting idea, but I get a compile error in my prototype. I think I need a break.

Bousole.h:23:73: error: ‘std:: ostream& Bousole:: operator<<(std:: ostream&, Bousole::Azimuth)’ must take exactly one argument
]

O_o

The form of `operator <<' you want is necessarily a non-member function.

Use the declaration Elysia gave.
