ArcObjects Library Reference (Geometry)

Path CoClass

A sequence of connected segments.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

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.
