Creates a bezier segment based on a start and end point and two control points at tangents to the start and end points.
The spatial reference parameter is used if the points have a nil spatial reference. If more than one spatial reference is supplied (as a parameter or as a property of an AGSPoint parameter), they must all be equal.
The z-value and m-value of the start and end points (if present) are used in the AGSCubicBezierSegment. The z-value and m-value of the control points (if present) are ignored.
- Parameters
-
startPoint The start point of the segment. controlPoint1 A point tangent to the start of the segment. controlPoint2 A point tangent to the end of the segment. endPoint The end point of the segment. spatialReference A spatial reference to use for the segment if the points do not have spatial references set.

NO if the object is an AGSLineSegment, YES otherwise.
Prior to v100.12, only AGSLineSegment instances were supported when creating new geometries using an AGSMultipartBuilder or iterating the AGSSegment instances in an existing AGSMultipart geometry.
From v100.12, you can add curve segments (AGSCubicBezierSegment, AGSEllipticArcSegment) when using an AGSMultipartBuilder, and get them back from an existing AGSMultipart geometry when AGSGeometry::hasCurves is YES.
