Detailed Description

length error exception

Thrown when the sample length of two timeSeries objects in a comparison or arithmetic operation are not the same.

Constructor & Destructor Documentation

Length_error::Length_error	(	std::string	p,
		std::string	n1,
		std::string	n2,
		const int	len1,
		const int	len2
	)			[inline]

Parameters:

	p	a string describing the offending operation
	n1	the name of a timeSeries
	n2	the name of a timeSeries
	len1	the length of timeSeries n1
	len2	the length of timeSeries n2

The information used to construct the Length_error exception can be used by the debug_print method to generate readable error messages for the user

Example: The timeSeries > operator can throw a Length_error:

         if (d.length() != ts.length()) {
             throw Length_error(">",d.varName,ts.varName,d.length(),ts.length());
         }

error message

Example:

This code:

        try {
            timeSeries<float> throttle("CFS_Accelerator_Pedal_Position",data);
            timeSeries<float> swa("CFS_Steering_Wheel_Angle",data); 

            boolResult bad = (throttle > swa.range(0,50));
        }
        catch (tsException& tse) {
            tse.debug_print();
            cerr << "skipping to next file..." << endl;
        }

Results in this error message:

		Illegal operation: (>) CFS_Accelerator_Pedal_Position has length 6952
		                       CFS_Steering_Wheel_Angle has length 51
		skipping to next file...
