ArcObjects Library Reference (NetworkAnalyst)

NAServerRecordSet CoClass

Deprecated as of 10.0. A container for a RecordSet of network locations.

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
INAServerLocations	Deprecated as of 10.0. Provides access to objects that can be used to load network locations in NAServer.
INAServerLocations2	Deprecated as of 10.0. Provides access to objects that can be used to load network locations in NAServer.
INAServerRecordSet	Deprecated as of 10.0. Provides access to a RecordSet containing network locations.
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

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 NAServerRecordSet object holds a RecordSet object representing network locations.

The NAServerRecordSet object can be passed into any of the properties of the NAServerSolverParams objects that expect an INAServerLocations interface pointer (for example, Stops, Barriers, Facilities, or Incidents).

At a minimum, the RecordSet needs a shape field with a point geometry type. You can also add fields to be used when loading the network locations. For example, if you specify the network location fields "SourceID" (int), "SourceOID" (int), "PosAlong" (double), and "SideOfEdge" (int), the values in these fields will specify the network location rather than perform a spatial search to determine the network location.

Any other fields can be added to the RecordSet and can be used when loading network locations. INAServerSolverParams.NAClassCandidateFieldMaps determines which properties map to NAClass fields.
