Constructor & Destructor Documentation

CLRelAbsVector::CLRelAbsVector	(	double	a = 0.0,
		double	r = 0.0
	)

Constructor with two values. First value sets the absolute value, econd sets the relative value.

Definition at line 30 of file CLRelAbsVector.cpp.

Referenced by operator+(), and operator/().

CLRelAbsVector::CLRelAbsVector

(

const std::string &

coordString

)

Constructor with a string. The string has to be parsed. If the string does not represent a valid value, the relative and the absolute component of the CLRelAbsVector are set to NaN.

Constructor with two values. First value sets the absolute value, econd sets the relative value.
