I suggest that you consider either or both of two approaches:

  1. Define subclasses.   Override the “throw an exception” logic in each one.
  2. Define a single exception-type but allow for a parameter to be sent to the exception handling routine (or reliably retrieved from the object in question), so that a common exception-handling routine can accurately distinguish among the various cases.

“Always keep your eye on the ball.”   Your objective is to be able to easily distinguish between the various objects and error cases; nothing more or less.   “TMTOWTDI!”   Don’t become too wedded to the first approach that pops into your head, then spend too much time trying to implement it.   Always be prepared to step back, to look at the objective afresh, and look for another equally-good way to get there.
