Short answer: No, no.

Longer answer: C ++ is not reflected. That is, there is no way to parse unknown data structures at runtime. You will have to write the dump procedures yourself for any data structure that you want to reset based on what is available to its data members.

However, note that C ++ has many tools to make this easier. For example, for a simple simple template dump():

template< typename T >
inline void dump(std::ostream& os, const T& obj) {os << obj;}

:

template< typename OutIt >
void dump(std::ostream& os, OutIt begin, OutIt end)
{
  if(begin != end)
    os << *begin++;
  while(begin != end) {
    os << ", ";
    dump(*begin++);
  }
}
