MultiCurve is a geometry collection
MultiCurve is a noninstantiable class.
MultiCurveis a one-dimensional geometry.
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.
MultiCurveboundary is obtained by applying the “mod 2 union rule” (also known as the “odd-even rule”): A point is in the boundary of a
MultiCurveif it is in the boundaries of an odd number of
MultiCurveis closed if all of its elements are closed.
The boundary of a closed
MultiCurveis always empty.
