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. |
| IConstructPath | Provides access to members that construct a path using other geometries and measures. |
| ICurve | Provides access to properties and methods of all 1 dimensional curves (polylines, segments, boundaries of polygons, etc.). |
| IGeometry | Provides access to members that describe properties and behavior of all geometric objects. |
| IPath | Provides access to members that identify a path and define its behavior. |
| IPointCollection | Provides access to members that manipulate the points of a Multipoint, Path, Ring, Polyline, Polygon, TriangleFan, TriangleStrip, or MultiPatch. |
| IPointCollection3 | Provides access to members that manipulate the points of a Multipoint. |
| IPointCollection4 | Provides access to members that manipulate the points of a Multipoint, Path, Ring, Polyline, Polygon, TriangleFan, TriangleStrip, or MultiPatch. |
| ISegmentCollection | Provides access to members that manipulate the segments of a path, ring, polyline, or polygon. |
| ISupportErrorInfo | Indicates whether a specific interface can return Automation error objects. |
| ITransform2D | Provides access to methods for transforming geometries using either specific parameters or arbitrary transformation objects (affine transformations, geographic transformations, etc.). |
| ITransform3D | Provides access to methods for transforming 3D geometries using either specific parameters or arbitrary transformation objects. |
| IXMLSerialize (esriSystem) | Provides access to members that XML serialize and deserialize an object to/from XML. |
