This object is new at ArcGIS 9.3.
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
| Interfaces | Description |
|---|---|
| IClone (esriSystem) | Provides access to members that control cloning of objects. |
| IPersist | Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile. |
| IPersistStream (esriSystem) | |
| ISpatialReferenceAuthority | Provides access to the authority-related metadata for a spatial reference object. |
| ISupportErrorInfo | Indicates whether a specific interface can return Automation error objects. |
| ITransformation | Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on. |
| ITransformationGEN | Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on. ITransformationGEN is generic version of ITransformation. |
