Creates a datum.
Windows, Solaris, Linux
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.
|IClone (esriSystem)||Provides access to members that control cloning of objects.|
|IDatum||Provides access to members that control the properties of all horizontal datums.|
|IDatumEdit||Provides access to members that control the properties of a horizontal datum.|
|IESRISpatialReference||Provides access to members that control the import/export operations components of a spatial reference system. This interface is same as IESRISpatialReferenceGEN.|
|IESRISpatialReferenceGEN||Provides access to members that generate well known string (WKS) representations of spatial reference objects.|
|IESRISpatialReferenceGEN2||Provides access to members that generate well known string representations for spatial reference objects. The strings include authority metadata.|
|IHVDatum||Indicator interface for a horizontal or vertical.|
|ISpatialReferenceAuthority||Provides access to the authority-related metadata for a spatial reference object.|
|ISpatialReferenceInfo||Provides access to members that control the properties common to all components of a spatial reference system.|
The IClone::IsIdentical method is not implemented.
