Unfortunately, I've done something similar at work recently.
public class PersonMapping : ClassMap<Person>
{
public PersonMapping()
{
Id(x => x.ID).GeneratedBy.GuidComb();
Map(x => x.Name).Not.Nullable();
JoinedSubClass<BoardMember>("ID", sm => MapBoardMember(sm));
}
private void MapBoardMember(JoinedSubClassPart<BoardMember> bm)
{
bm.Map(x => x.Type).Not.Nullable();
bm.JoinedSubClass<Chairman>("ID", sm => MapChairman(sm));
}
private void MapChairman(JoinedSubClassPart<Chairman> cm)
{
cm.Map(x => x.SomeOtherProperty);
}
}
