MultiCurve is a geometry collection
MultiCurve is a non-instantiable class.
MultiCurve is a one-dimensional
MultiCurve is 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.
MultiCurve boundary is obtained by
applying the 「mod 2 union rule」 (also known as
the 「odd-even rule」): A point is in the
boundary of a
MultiCurve if it is in the
boundaries of an odd number of
MultiCurve is closed if all of its
elements are closed.
The boundary of a closed
