There would be quite a bit of work to do. You would have to:
- add a constructor to boost::shared_ptr in common.i so that it takes a
pointer;
- modify the exported payoff classes so that they no longer hide the
shared_ptr (e.g., export the actual PlainVanillaPayoff, not
PlainVanillaPayoffPtr) and enable directors;
- export the shared_ptr<Payoff> as a separate class;
- fix the other interfaces so that they work with the new classes.
Let me know if you get stuck in any of the steps.
