GeocodingIndexClassExtensionClass Class

A class extension for building and maintaining geocoding indexes.

Product Availability

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


The GeocodingIndexClassExtension is an object class extension for geocoding index Tables that are automatically maintained. This object only applies to pre-9.2 locator indexes.

Supported Platforms

Windows, Solaris, Linux

Extended Error Information

Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.


Interfaces Description
IClassExtension (esriGeoDatabase) Provides access to members that initialize and shutdown the class extension.
IGeocodingIndexCompute Provides access to members that calculate geocoding index values.
IObjectClassExtension (esriGeoDatabase) Indicator interface for object class extensions.
IRelatedObjectClassEvents (esriGeoDatabase) Provides access to events that occur when related objects are created.
ISupportErrorInfo (esriSystem)


When you register a Table as a geocoding index, use the IClassSchemaEdit::AlterClassExtensionCLSID method. With this method, you must specify a PropertySet that contains properties for the object class extension. The properties that this PropertySet must contain are:

For an example of setting up a geocoding index Table so that it is maintained automatically, see the Geocoding Index Maintenance sample in the Developer Samples section of the ArcObjects Developer Help system.
