ArcObjects Library Reference (GeoDatabase)

IGeometryDef Interface

Provides access to members that return information about the geometry definition.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Members

	Name	Description
	AvgNumPoints	The estimated average number of points per feature.
	GeometryType	The enumerated geometry type.
	GridCount	The number of spatial index grids.
	GridSize	The size of a spatial index grid.
	HasM	Indicates if the feature class has measure (M) values.
	HasZ	Indicates if the featureClass has Z values.
	SpatialReference	The spatial reference for the dataset.

CoClasses that implement IGeometryDef

CoClasses and Classes	Description
GeometryDef	Esri Geometry Definition object.

Remarks

The IGeometryDef interface provides read-only access to the GeometryDef properties.

The AvgNumPoints, GridCount and GridSize properties are all attributes of the geodatabase spatial index. Shapefiles will return 0 for GridCount.

[C#]

The following code shows how to get the GeometryDef of a feature class:

// Get the GeometryDef from the feature class's shape field.
String shapeFieldName=featureClass.ShapeFieldName;
int shapeFieldIndex=featureClass.FindField(shapeFieldName);
IFields fields=featureClass.Fields;
IField shapeField=fields.get_Field(shapeFieldIndex);
IGeometryDef geometryDef=shapeField.GeometryDef;

[Visual Basic .NET]

The following code shows how to get the GeometryDef of a feature class:

' Get the GeometryDef from the feature class's shape field.
Dim shapeFieldName As String=featureClass.ShapeFieldName
Dim shapeFieldIndex As Integer=featureClass.FindField(shapeFieldName)
Dim fields As IFields=featureClass.Fields
Dim shapeField As IField=fields.Field(shapeFieldIndex)
Dim geometryDef As IGeometryDef=shapeField.GeometryDef
