|
This document is archived and information here might be outdated. Recommended version. |
Provides access to members that return information about the geometry definition.
| 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. |
| Classes | Description |
|---|---|
| GeometryDef | Esri Geometry Definition object. |
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.
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;
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
