Re: Private Virtual Methods

Contrary to what you say, the example fails to "illustrate the power
of this idea and why you should add this technique to your arsenal
[...]." Since Automobile::go() and Automobile::stop() do nothing
more than calling the virtual functions, the example would have
worked equally well without the public non-virtual functions and
with the virtual functions as public:
class Automobile {
public:
// ...
virtual void go() = 0;
virtual void stop() = 0;
};
The point of the post was to demonstrate separating the virtual
interface from the non-virtual public interface. The virtual interface
is meant to be overridden while the public interface is not. Of course
more functionality could have been put into the public interface to
make it more useful but this was not done in the interest of making
the post as short as possible to illustrate the central point.
