insertion points for custom domain/business logic

Hello,

How does Middlegen allow for the insertion of custom domain logic or 
business logic in generated classes when using the Hibernate plugin? 
Taking the Middlegen sample application (airline reservations) as a 
starting point: let's say I want the generated Flight object to have an 
additional getter method:

public long getFlightDuration() {
   return getArrivalUtc().getTime() - getDepartureUtc().getTime();
}

How do I do that?  Normally I'd expect to do something like that with 
XDoclet merge files, but I don't see exactly where that happens in the 
process.  Thanks in advance to anyone who can help me understand how 
this might work.
