public void LengthsAsync( IList<Graphic> graphics, Nullable<LinearUnit> lengthUnit, bool geodesic, object userToken ) | |
Remarks
This overload has been replaced by a new overload replace bool geodesic with CalculationType.Geodesic for true and CalculationType.Planar for false.
Parameters
- graphics
- The graphics used to calculate lengths.
- lengthUnit
- The length unit in which perimeters of polygons will be calculated. If unit is not specified, the units are derived from the Spatial Reference of the geometry.
- geodesic
- If polylines are in geographic coordinate system, then geodesic needs to be set to true in order to calculate the ellipsoidal shortest path distance between each pair of the vertices in the polylines. The output if lengthUnit is not specified is returned in meters.
- userToken
- A user-defined object that is passed to the method invoked.
Requirements
