EDN: ESRI Developer Network
A 2D straight line between a pair of 2D endpoints; can optionally have height, measure and ID attributes at each endpoint.
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 |
|---|---|
| IClone (esriSystem) | Provides access to members that control cloning of objects. |
| IConstructLine | Provides access to members that construct a line segment using other geometries and measures. |
| ICurve | Provides access to properties and methods of all 1 dimensional curves (polylines, segments, boundaries of polygons, etc.). |
| ICurve2 | Provides access to members that extend the functionality of one dimensional curves. |
| ICurve3 | Provides access to members that extend the functionality of one dimensional curves. |
| IGeometry | Provides access to members that describe properties and behavior of all geometric objects. |
| ILine | Provides access to members that identify a straight line segment and defines its properties. |
| ILine2 | Provides access to the coordinates of a line segment in the form of Well Known Structures (WKS). |
| IProximityOperator | Provides access to members that find the distance between two geometries. Not currently implemented for geometries containing elliptic arcs. |
| ISegment | Provides access to members that identify a segment. A segment is a way of getting between two endpoints. |
| ISegmentID | Provides access to members that allow simple manipulations of IDs at the segment level. |
| ISegmentM | Provides access to members that allow simple manipulations of Ms at the segment level. |
| ISegmentZ | Provides access to members that allow simple manipulations of Zs at the segment level. |
| 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.). |
