c++ - When should you not use virtual destructors?

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

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 in a pointer of a superclass

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