As explained in Product 39, for a standard member operate, the selection is concerning enabling it being named by using a pointer to Base nonvirtually (but possibly with virtual behavior if it invokes virtual capabilities, including in the NVI or Template Process patterns), just about, or under no circumstances. The NVI sample is a method to stay away from general public virtual capabilities.
