Detailed Description

ByteString is String holder implementor.

Every character is stored as single byte. It is good idea not to use this class directly. Use String instead.

String * ByteString::className (  void   )  const [virtual]
 

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).
