Methods

distance(Point from, Point to) → double?

Computes the distance between from and to positions. Returns a 3D distance when Point.altitude are set in both positions, otherwise a 2D distance is returned. from and to must have geometry-based coordinates; if this is not the case, the function returns null. See also DistanceCalculator2D.

override

measure(Shape shape) → double?

Computes the 3D length of a line or polygon. null is returned iif any Point in the line or polygon is not geometry-based. If all points have a null altitude, returns a 2D distance. If some points have their altitude set while some others do not, the resulting distance may be inconsistent as some segments will be measured in 2D and others in 3D.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

toString() → String

A string representation of this object.
