Class variables: public access read-only, but private access read/write

Question

Whoopee, not working on that socket library for the moment. I\'m trying to educate myself a little more in C++.

With classes, is there a way to make a variable read-

Answer 1

As mentioned in other answers, you can create read only functionality for a class member by making it private and defining a getter function but no setter. But that's a lot of work to do for every class member.

You can also use macros to generate getter functions automatically:

#define get_trick(...) get_
#define readonly(type, name) \
private: type name; \
public: type get_trick()name() {\
    return name;\
}

Then you can make the class this way:

class myClass {
    readonly(int, x)
}

which expands to

class myClass {
    private: int x;
    public: int get_x() {
        return x;
    }
}
