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

		Description
	AvgNumPoints	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#]     public void IGeometryDef__(IFeatureClass featureClass)
    {
        //The code below shows how to get to IGeometryDef from a feature class.
        string shapeFieldName = featureClass.ShapeFieldName;
        IFields fields = featureClass.Fields;
        int geometryIndex = fields.FindField(shapeFieldName);
        IField field = fields.get_Field(geometryIndex);
        IGeometryDef geometryDef = field.GeometryDef;
    }

[Visual Basic 6.0] The code below shows how to get to IGeometryDef from a feature class.

Dim lGeomIndex As Long
Dim sShpName As String
Dim pFields As IFields
Dim pField As IField
Dim pGeometryDef As IGeometryDef
sShpName = pFeatureClass.ShapeFieldName
Set pFields = pFeatureClass.Fields
lGeomIndex = pFields.FindField(sShpName)
Set pField = pFields.Field(lGeomIndex)
Set pGeometryDef = pField.GeometryDef
