hicpp-exception-baseclass¶
Ensure that every value that in a throw expression is an instance of
std::exception.
This enforces rule 15.1 of the High Integrity C++ Coding Standard.
class custom_exception {};
void throwing() noexcept(false) {
  // Problematic throw expressions.
  throw int(42);
  throw custom_exception();
}
class mathematical_error : public std::exception {};
void throwing2() noexcept(false) {
  // These kind of throws are ok.
  throw mathematical_error();
  throw std::runtime_error();
  throw std::exception();
}
