IObjectClassDescription Interface

Provides access to members that control Object Class Description.

Description

The IObjectClassDescriptioninterface provides configuration information for ArcCatalog and custom clients to use when creating a new object class or feature class. This interface can be implemented on a class extension or a separate coclass. Regardless of where the interface is implemented, the implementing coclass must be registered to the "ESRI GeoObject Class Descriptions" category using the Component Category Manager. If a feature class is being created, the class description (or class extension) must also implement IFeatureClassDescription.

If the .NET framework is being used, a class description can also be registered using the GeoObjectClassDescriptions static class in the ESRI.ArcGIS.ADF.CATIDs namespace.
