Detailed Description

Exception class deriving from std::exception.

This class provides a syntax similar to output-streams for convenience. For compability with other libraries it is inheriting the class std::exception.

Here is an example how to use an instance of this class (by invoking the macro MMERROR):

    void test( int i ) throw (exception)
    {
      MMERROR( i > 0, exception, ,
               "Parameter for method test must be greater than zero (but was "
               << i << ")." );
    }
    
    int main(void)
    {
      try {
        test( -5 );
      } catch ( exception &e ) {
        cerr << e.what() << endl;
      };
      return 0;
    }

Mind that the macro uses a variable with the name _e. Make sure, that you don't use this variable-name in any of the macro-arguments!
