A container for the closest facility solver settings and return parameters used by NAServer.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Network Analyst Extension.
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 |
|---|---|
| INAClosestFacilitySolver | Provides access to the closest facility solver. |
| INAServerClosestFacilityParams | Provides access to properties that specify the closest facility solver settings and return parameters used during network analysis with NAServer. |
| INAServerClosestFacilityParams2 | Provides access to properties that specify the route solver settings and return parameters used during network analysis with NAServer. |
| INAServerClosestFacilityParams3 | Provides access to properties that specify the route solver settings and return parameters used during network analysis with NAServer. |
| INAServerSolverParams | Provides access to properties that specify the solver settings and return parameters used during network analysis with NAServer. |
| INAServerSolverParams2 | Provides access to properties that specify the solver settings and return parameters used during network analysis with NAServer. |
| INASolverOutputGeneralization | Provides access to generalization parameters used on solver output. |
| INASolverSettings | Provides access to settings common to all solvers. |
| INASolverSettings2 | Provides access to settings common to all solvers. |
| IPersist | Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile. |
| IPersistStream (esriSystem) | |
| ISupportErrorInfo | Indicates whether a specific interface can return Automation error objects. |
| IXMLSerialize (esriSystem) | Provides access to members that XML serialize and deserialize an object to/from XML. |
| IXMLVersionSupport (esriSystem) | Provides access to members that help in serializing an object to different namespaces (versions). |
Remarks
NAServerClosestFacilityParams is used to pass solver settings and return parameters to the NAServer when performing stateless network analysis.
