“Destructors for virtual base classes are executed in the reverse order of their appearance in a depth-first left-to-right traversal of the directed acyclic graph of base classes.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Destructors for virtual bases run in reverse order of a depth‑first left‑to‑right traversal of the inheritance graph.
In simple terms: Virtual base destructors run opposite to their appearance order.
