Detailed Description

dimension error exception

Thrown when the vector dimension of two timeSeriesArray objects in an arithmetic operation are not the same.

---

Constructor & Destructor Documentation

Dimension_error::Dimension_error	(	std::string	p,
		std::string	n1,
		std::string	n2,
		const int	dim1,
		const int	dim2
	)			[inline]

Parameters:

	p	a string describing the offending operation
	n1	the name of a timeSeriesArray
	n2	the name of a timeSeriesArray
	dim1	the dimension of timeSeriesArray n1
	dim2	the dimension of timeSeriesArray n2

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

Example: the timeSeriesArray + operator can throw Dimension_error:

         if (d.get_nElem() != ts.get_nElem()) {
             throw Dimension_error("+",d.varName,ts.varName,
                                   d.get_nElem(),ts.get_nElem());
         }

error message

Example:

This code:

        try {
            timeSeriesArray<float> lanedev("SCC_Lane_Deviation",data);
            timeSeriesArray<float> objhead("SCC_DynObj_Heading",data);
            
            timeSeriesArray<float> bad = lanedev + objhead;
        }
        catch (tsException& tse) {
            tse.debug_print();
            cerr << "skipping to next file..." << endl;
        }

Results in this error message:

		Illegal operation: (+) SCC_Lane_Deviation has dimension 4
		                       SCC_DynObj_Heading has dimension 20
		skipping to next file...
