Artifact 9b225aa65d88ce4310b1a37db74ed0ab3502f70ae00ae52afc63d47e85030492:

• File src/exceptions/OFAddressTranslationFailedException.m — part of check-in [8d2a5052fd] at 2014-01-25 17:39:13 on branch trunk — Generalize stream / socket related exceptions

  This is in preparation for adding UDP sockets, as UDP sockets and TCP
  sockets have no common superclass, as one is stream-oriented while the
  other is packet-oriented.

  Read and write exceptions are for any object now, as they are useful for
  a lot more than just for streams, while the others (bind, listen, etc.)
  are for any socket now (the type is id in this case, though, as there is
  no common superclass). (user: js, size: 2976) [annotate] [blame] [check-ins using]
