[Boost-users] [serialization] unwinding "stack" of object during loading

Subject: [Boost-users] [serialization] unwinding "stack" of object during loading

Hello,

Consider the following structure:

struct outer
{
  inner_type1 inner1_;
  inner_type2  inner2_;

  template<class Archive>
  void HostPort::load(Archive &ar, const unsigned int version)
  {
    ar >> BOOST_SERIALIZATION_NVP(inner1_);
    ar >> BOOST_SERIALIZATION_NVP(inner2_);
  }
};

Assume that loading of inner1_ throws exception. Is there a way to
"unwind" the "stack" of objects gracefully (i.e. to skip until some
"end" marker of inner1_), and to proceed loading the next inner object
normally?

Thanks.
