• File src/exceptions/OFUnboundPrefixException.m — part of check-in [3d16a30f41] at 2013-06-22 12:12:36 on branch trunk — Rework exceptions.

  This mostly removes the argument for the class in which the exception
  occurred. As backtraces were recently added for all platforms, the
  passed class does not give any extra information on where the exception
  occurred anymore.

  This also removes a few other arguments which were not too helpful. In
  the past, the idea was to pass as many arguments as possible so that it
  is easier to find the origin of the exception. However, as backtraces
  are a much better way to find the origin, those are not useful anymore
  and just make the exception more cumbersome to use. The rule is now to
  only pass arguments that might help in recovering from the exception or
  provide information that is otherwise not easily accessible. (user: js, size: 1675) [annotate] [blame] [check-ins using]
