Deprecated as of 10.0. A MapServer object extension for performing network analysis within a stateless environment.

Remarks

At version 10.1, ArcGIS for Server no longer supports performing network analysis via local connections using the GISServer and GISClient APIs. Use the SOAP or REST API instead.

The NAServer is a MapServer object extension that can be used to perform network analysis in a stateless environment using ArcGIS for Server.

                                    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:

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 NAServer 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.

Handles REST requests for SOE.

This method is invoked by ArcGIS Server's REST handler, which intercepts client's request (in URL form), parses it and passes it on to this method in form of parameter values.

The REST SOE developer must add logic to use these parameter values to determine which resource/operation is being requested and accordingly handle these requests and generate responses in the output format indicated by the "outputFormat" parameter. For more information on developing REST SOEs, please consult the Java ArcObjects Developer Guide.

Developer doc: Developing extensions > Server Object Extensions > SOE Web Services > REST Web Services > Developing SOE REST Web Services
Samples: Samples > Server Object Extensions section

Specified by:

handleRESTRequest in interface IRESTRequestHandler

Parameters:

capabilities - The capabilities supported by the SOE. An admin can choose which capabilities are enabled on a particular SOE (in ArcGIS Manager or ArcCatalog), based on certain criteria such as security roles. This list of allowed capabilities is then sent to this method, at runtime, as a comma separated list. (in)

resourceName - Name of the resource being addressed. If empty, its assumed that root resource is being addressed. (in)

operationName - Name of the operation being invoked. If empty, description of resource is returned. (in)

operationInput - Input parameters, in form of comma separated list, to the operation specified by operationName parameter. (in)

outputFormat - OutputFormat of operation. Possible formats are JSON, HTML, AMF, etc. (in)

requestProperties - The requestProperties (in)

responseProperties - The responseProperties (out)

Returns:

Output generated by the SOE

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getSchema

public String getSchema()
                 throws IOException,
                        AutomationException

This method returns the resource hierarchy of a REST based SOE. This hierarchy is in JSON format as shown in the example below:

For an SOE that has a root resource (called "root") with one operation ("operation0"), and 2 sub-resources with one operation each ("operation1" and "operation2" respectively), the schema would look like:

 {
   "name": "MyRESTSOE",
   "description": "My REST SOE with 3 resources and 1 operation each.",
   "isCollection": false,
   "operations": [
   {
      "name": "operation0",
      "parameters": ["param01"],
      "supportedOutputFormats": ["json"]
    }
 ],
 "resources": [
  {
      "name": "subresource1",
      "description": "Sub Resource 1",
      "isCollection": true,
      "operations": [
       {
          "name": "operation1",
          "parameters": ["param10", "param11"],

       }
    ]
  },
