public class KnotType
extends CodeList<KnotType>

The type of a B-spline. A B-spline is uniform if and only if all knots are of multiplicity 1 and they differ by a positive constant from the preceding knot. A B-spline is quasi-uniform if and only if the knots are of multiplicity (degree+1) at the ends, of multiplicity 1 elsewhere, and they differ by a positive constant from the preceding knot. This code list is used to describe the distribution of knots in the parameter space of various splines.
