Detailed Description

Exception class.

Smart exception class. Tracking of:

• file name
• line number
• function name of the exception location. The exception message can be stack with any other previously thrown exception. Use the pre-processor macro to throw an exception:

  MARLINMT_THROW( "A problem occured" );

  An exception can rethrown:

  try {
    // ... some code
  }
  catch ( const marlinmt::Exception &e ) {
    MARLINMT_RETHROW( e, "A problem occured" );
  }

  In this case, the message will appended to the previous exception message
