Product Availability
Available with ArcGIS Desktop.
Description
The TracePathTask object finds a path on the current network between all flags on the current network.
Supported Platforms
Windows
Interfaces
| Interfaces | Description |
|---|---|
| ITracePathTaskResults | Provides access to members that return cost information about the path or tree found by certain trace tasks. |
| ITraceTask | Provides access to members that execute a trace task. |
| ITraceTaskResults | Provides access to members that return the network elements returned by the trace task. |
Remarks
The flags you place on the network must be either all edge flags or all junction flags. You cannot find a path among a mixture of edge and junction flags.
If sets of flags are placed on different connected components in the network, the TracePathTask will attempt to find a path for each connected component.
If you do not specify weights for your trace task, the TracePathTask will return the path with the fewest number of network elements.
If you do specify weights for your trace task, the TracePathTask will treat network elements with negative weight values as having infinite cost.
