Interface IGeometryDef

All Superinterfaces:

Serializable

All Known Subinterfaces:

IGeometryDefEdit

All Known Implementing Classes:

GeometryDef

public interface IGeometryDef
extends Serializable

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

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.

Product Availability

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