Default solver parameters for the specified network analysis layer.

Remarks

GetSolverParameters returns the NAServerSolverParams object (NAServerRouteParams, NAServerClosestFacilityParams, NAServerServiceAreaParams, NAServerLocationAllocationParams, NAServerODCostMatrixParams, NAServerVRPParams) corresponding to the NALayer name passed in. The parameter object returned will have defaults based on the NALayer it is referencing.

You can pass this resulting object into the Solve method on INAServer to perform network analysis.

Product Availability

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

public INAServerSolverResults solve(INAServerSolverParams nAServerSolverParams)
                             throws IOException,
                                    AutomationException

Perform network analysis based on the input solve parameters.

Remarks

Solve performs network analysis based on the NAServerSolverParams object (NAServerRouteParams, NAServerClosestFacilityParams, NAServerServiceAreaParams) that was passed in and returns it's output through an NAServerSolverResults object (NAServerRouteResults, NAServerClosestFacilityResults, NAServerServiceAreaParams).

Product Availability

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

Specified by:

solve in interface INAServer

Parameters:

nAServerSolverParams - A reference to a com.esri.arcgis.networkanalyst.INAServerSolverParams (in)

Returns:

A reference to a com.esri.arcgis.networkanalyst.INAServerSolverResults

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getSolverParameters2

public INAServerSolverParams getSolverParameters2(String nALayerName,
                                                  String layerToken,
                                                  boolean populateNAClasses)
                                           throws IOException,
                                                  AutomationException

Default solver parameters for the specified network analysis layer.

Remarks

GetSolverParameters2 returns the NAServerSolverParams object (NAServerRouteParams, NAServerClosestFacilityParams, NAServerServiceAreaParams, NAServerLocationAllocationParams, NAServerODCostMatrixParams, NAServerVRPParams) corresponding to the NALayerName and LayerToken passed in. if PopulateNAClasses was set to True, returned NAServerSolverParams instance will contain correspondent recordsets populated with content of NAClasses.

As opposed to GetSolverParameters, NAServerSolverParams instance returned by GetSolverParameters2 does not contain MapDescription and ImageDescription populated, which significantly reduces response size.

You can pass this resulting object into the Solve method on INAServer to perform network analysis.

LayerToken can be obtained from NAServerSolverResults object if the instance of NAServerSolverParams previously passed to the Solve method had SaveLayerOnServer set to True.

This method can be useful when, for example, multiple clients are working with a shared network analysis layer stored on server, or shared layer originally was created and saved on server by another client process.

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

Specified by:

getSolverParameters2 in interface INAServer2

Parameters:

nALayerName - The nALayerName (in)
