NAServerDataLayer	Deprecated as of 10.0. A container that references a data layer containing network locations.

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 INAServerDataLayer interface provides access to a feature layer in the associated map service to load as network locations into an input network analysis class.

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

If the data layer contains 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 in the data layer and can be used when loading network locations. Which fields map to the NAClass fields is a function of INAServerSolverParams.NAClassCandidateFieldMaps.
