This allow this * class to be used as the message arguments in macros. * * The constructed object is either a Message with a single detail string if * a string was passed to the macro, or a copy of the Message passed to the macro. * * Here is an example of usage: * \code *  *   void checkStringEquals( const std::string &expected, *                          const std::string &actual, *                           const CppUnit::SourceLine &sourceLine, *                           const CppUnit::AdditionalMessage &message ); *   *   #define XTLUT_ASSERT_STRING_EQUAL_MESSAGE( expected, actual, message )  \ *     ::XtlUt::Impl::checkStringEquals( ::Xtl::toString(expected),        \ *                                       ::Xtl::toString(actual),          \ *                                       CPPUNIT_SOURCELINE(),             \ *                                       message ) * \endcode * * In the previous example, the user can specify a simple string for \a message, * or a complex Message object. * * \see Message */class CPPUNIT_API AdditionalMessage : public Message{public:  typedef Message SuperClass;  /// Constructs an empty Message.
