public abstract class SegmentedCurve
extends SortedVector
implements Curve

A SegmentedCurve is a curve that consists of multiple segments defined by an ordered sequence of boundary CurvePoints (e.g., a linearly interpolated curve).
An ordered sequence of N boundary CurvePoints {(x[0], y[0]), (x[1], y[1]), ..., (x[N-1], y[N-1])} (where x[0] < x[1] < ... < x[N-1]) defines (N+1) segments as follows:

segment 0: (-infinity, x[0])
segment k (k = 1, 2, ..., N-1): [x[k - 1], x[k])
segment N: [x[N-1], +infinity)

SegmentedCurve()

getSegmentIndex(double): Returns the index of the segment to which a given value x belongs.
getValueInSegment(double, int): Defines the value for a given point x in index-th segment.
getValueOf(double): The value of this Curve.

SegmentedCurve

 public SegmentedCurve()

getSegmentIndex

 public int getSegmentIndex(double x)

Returns the index of the segment to which a given value x belongs. It returns -1 if there is no boundary points.

getValueInSegment

 public abstract double getValueInSegment(double x,
                                          int index)

Defines the value for a given point x in index-th segment. This is abstract.

getValueOf

 public double getValueOf(double x)

The value of this Curve.
