NAClosestFacilitySolver Class (ArcObjects .NET 10.8 SDK)
|
This document is archived and information here might be outdated. Recommended version. |
Performs closest facility analysis.
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.

NAClosestFacilitySolver is a Network Analyst solver that finds a set of closest facilities from a set of incidents. It can find the closest facility based on any suitable cost attribute and then write the results to an in-memory feature class. It has options to limit the number of facilities to compute to/from any incident by either specifying a maximum number of facilities to find or by specifying a cutoff value. For example, find the three closest facilities from a set of incidents that are no more than 10 Km away. It can also generate the actual path or straight line geometries connecting each facility to each incident. The NAClosestFacilitySolver honors all of the settings of the INASolverSettings interface.
