Oops, I made a little naming mistake: base_ptr should be derived_ptr.
BTW, compile-time retrospection could be used to find library-specific
constructor. For example, Driver could have it:
class Driver : public Person
{
std::string licence_id;
Date licence_issue_date;
public:
Driver(const raw_object& raw)
: Person(raw)
, licence_id(raw.get(&Driver::licence_id))
, licence_issue_date(raw.get(&Driver::licence_issue_date))
{
}
// ..
};
If this information isn't available at compile-time you have to tell the
framework about the constructor:
void describe_Driver(descriptor<Driver>& class_)
{
class_("Driver").derived_from<Person>()
[
constructor<const raw_object&>(), // here
member(&Driver::licence_id, "licence_id"),
member(&Driver::licence_issue_date, "licence_issue_date")
];
}
