Trivial Description
In PolynomialSplineFunction constructor, it tests whether length of knots is smaller than 2 or not. If <2, it throws NumberIsTooSmallException like below:
if (knots.length < 2) { throw new NumberIsTooSmallException(LocalizedFormats.NOT_ENOUGH_POINTS_IN_SPLINE_PARTITION, 2, knots.length, false); }
But definition of above exception has parameters of the form:
/**
* Construct the exception with a specific context.
*
* @param specific Specific context pattern.
* @param wrong Value that is smaller than the minimum.
* @param min Minimum.
* @param boundIsAllowed Whether {@code min} is included in the allowed range.
*/
public NumberIsTooSmallException(Localizable specific,
Number wrong,
Number min,
boolean boundIsAllowed) {
super(specific, wrong, min);
this.min = min;
this.boundIsAllowed = boundIsAllowed;
}
In my opinion, 2, knots.length, false should be knots.length, 2, true
since 2 is the minimum value and knots.length is the wrong value in this case. Moreover, boolean should be set by true because 2 is also acceptable.
