IsMSimple Method (IGeometryEngine)

In This Topic

Determines if all the M-values are numbers.

Syntax

C#
Visual Basic (Declaration)

bool IsMSimple( 
   Geometry geometry
)

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

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 polyline = PolylineBuilderEx.CreatePolyline(coords); // polyline.HasM = false
bool isMSimple = GeometryEngine.Instance.IsMSimple(polyline); // isMSimple = false

PolylineBuilderEx polylineBuilder = new PolylineBuilderEx(polyline);
polylineBuilder.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
