Accessor functions

Hi.

I was wondering if these accessor functions (or even the comments) are worth keeping. From value.h:

    //! Gets the loop option.
    bool get_loop()const { return loop_; }

    //! Sets the loop option.
    void set_loop(bool x) { loop_=x; }

    //! Gets the static option.
    bool get_static()const { return static_; }

    //! Sets the static option.
    void set_static(bool x) { static_=x; }

It seems unnecessary to me, but I usually program in C.

Thanks,
Charlie

Hi!
Those accessors are needed since those values are protected on the class. So to allow external classes not friend of ValueBase should use those accessors.

Ah, I see. Thanks!

Why are those variables protected when they could be public?

because encapsulation, inheritance and information/data control…
what would happen if a data is set out of bounds ?
what would happen if path/string contain forbidden char ?
