Detailed Description

StringImpl is base class for concrete string implementors.

These are really poor in functionality so use String instead.

String * TwoByteString::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).
