When should you not use virtual destructors?

Question

Is there ever a good reason to not declare a virtual destructor for a class? When should you specifically avoid writing one?

Answer 1

There is no need to use a virtual destructor when any of the below is true:

• No intention to derive classes from it
• No instantiation on the heap
• No intention to store with access via a pointer to a superclass

No specific reason to avoid it unless you are really so pressed for memory.
