A MultiCurve is a geometry collection
composed of Curve elements.
MultiCurve is a non-instantiable class.
MultiCurve
Properties
A
MultiCurveis a one-dimensional geometry.A
MultiCurveis simple if and only if all of its elements are simple; the only intersections between any two elements occur at points that are on the boundaries of both elements.A
MultiCurveboundary is obtained by applying the 「mod 2 union rule」 (also known as the 「odd-even rule」): A point is in the boundary of aMultiCurveif it is in the boundaries of an odd number ofMultiCurveelements.A
MultiCurveis closed if all of its elements are closed.The boundary of a closed
MultiCurveis always empty.
