Flag declaration of the C array within a operate or class that also declares an STL container (to avoid extreme noisy warnings on legacy non-STL code). To repair: At least alter the C array to your std::array.
Just document that consumer code must get in touch with the publish-initialization perform appropriate immediately after developing an object.
As explained in Product 39, for a traditional member operate, the selection is amongst letting it to become termed through a pointer to Foundation nonvirtually (but probably with virtual conduct if it invokes Digital features, such as while in the NVI or Template Technique styles), just about, or under no circumstances.

If that's the case, keep them neighborhood, rather than “infecting” interfaces in order that greater teams of programmers should pay attention to the
Flag a parameter of a wise pointer sort (a sort that overloads operator-> or operator*) that's copyable/movable but never copied/moved from from the purpose physique, and that's hardly ever modified, and that isn't handed together to another operate that would accomplish that. Which means the possession semantics usually are not made use of.
