Answer receiver class name. Because there isn't any standard way to obtain class name this method comes to place. Every class should rewrite this method but many didn't (yet). Reimplemented from Core::CharacterEncoder. Definition at line 54 of file ByteCharacterEncoder.cc. 00055 {
00056 return new String("ByteCharacterEncoder");
00057 }
