If efficiency is your goal, exceptions are not the answer. Just enabling
exceptions at compile time makes a noticable performance hit. Actually
throwing an exception can gobble up a 1000 cycles, give or take. That's per
throw. If you catch and throw again, you'll pay again.
Now if you've got more than a hundred or so entries left to go, exceptions
really are the greener grass.
What's wrong with 'return', perhaps along-side some sort of 'done' status
variable? I'm only vaguely familiar with the vistor pattern, but these
would seem to be the obvious choice.
