In This Topic

Determines if all the M-values are numbers.

Syntax

Visual Basic (Declaration)
C#

Function IsMSimple( _
   ByVal geometry As Geometry _
) As Boolean

bool IsMSimple( 
   Geometry geometry
)

Parameters

geometry: The input geometry. Cannot be a GeometryBag.

Return Value

Returns true if none of the M-values are NaN and false otherwise. If the geometry is not M-Aware, then false is returned.

Exceptions

Exception	Description
System.ArgumentNullException	Geometry is null.
System.NotImplementedException	This method is not implemented for GeometryBag.

Example

Determine if all the M-values are numbers - IsMSimple

{
  Coordinate2D[] coords = [new Coordinate2D(-2, 2), new Coordinate2D(3, 5), new Coordinate2D(7, 2)];
  polyline = PolylineBuilderEx.CreatePolyline(coords); // polyline.HasM = false
  bool isMSimple = GeometryEngine.Instance.IsMSimple(polyline); // isMSimple = false

  PolylineBuilderEx polylineBuilder = new(polyline)
  {
    HasM = true
  };
  polyline = polylineBuilder.ToGeometry();
  isMSimple = GeometryEngine.Instance.IsMSimple(polyline); // isMSimple = false

  MapPoint point1 = MapPointBuilderEx.CreateMapPoint(-2, 2, -1, 1);
  MapPoint point2 = MapPointBuilderEx.CreateMapPoint(3, 5, -2, 2);
  MapPoint[] points = [point1, point2];
  polyline = PolylineBuilderEx.CreatePolyline(points, AttributeFlags.HasM);
  isMSimple = GeometryEngine.Instance.IsMSimple(polyline); // isMSimple = true
}
