RepresentationWorkspaceExtension CoClass

Workspace extension to support representations in a geodatabase.

Product Availability

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

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.

Remarks

RepresentationWorkspaceExtension is a workspace extension useful for creating and managing feature class representations. RepresentationClass is a feature class enabled with representation capability using RepresentationRules and Overrides stored within the geodatabase. Use IRepresentationWorkspace.CreateRepresentationClass method to add representation information to a feature class.

IRepresentationWorspaceExtension is the inteface that has methods and properties listed for representation classes present in a workspace.

New RepresentationRules object which is a collection of representation rules based on which features are rendered, has to be created or a reference to rules of an existing representation class has to be made prior to the convertion of a regular feature class into a representation class.
