Methods

Modifier and Type	Method and Description
double	arcLength(double positionA, double positionB) Gets the result of ∫ab|f'(t)| dt. That means it calculates the arc length (in meters) between positionA and positionB.
Vector	get1stDerivative(double position) Gets the result of f'(position).
Vector	getPosition(double position) Gets the result of f(position)
int	getSegment(double position)
void	setNodes(List<Node> nodes) Sets nodes to be used by subsequent calls to Interpolation.getPosition(double) and the other methods.
