Question

I need to have a way to serialize classes in my code into a string. Later on, using that string I would need to populate an instance of that class.

i.e.

enum AlarmStatus
{
   Clear=0,
   Active
};

class AlarmInfo
{
public:
std::string S;
int I;
AlarmStatus alarmStatus;
void setAlarmStatus(AlarmStatus alarmStatus);
AlarmStatus getAlarmStatus();
};

Any ideas how I can do that in code? I know boost have boost/archive/ library that can serialize a class but it is not a “HeaderOnly library”? Is there a library that is Header only?

Thank you

Create a to and from serial code and call that

struct Person{
  string name;
  int age;

  void toSerial(ostream& stream){ stream << name << age; }
  void fromSerial(istream& stream){  stream >> name >> age; }
}

int main(){
  Person person;
  //save to data.txt
  ofstream fileOut("data.txt");      
  person.toSerial(fileOut);
  fileOut.close();

  //load from data.txt
  ifstream fileIn("data.txt");
  person.fromSerial(fileIn);

}
