Class NACompactStreetDirectionsAgent

java.lang.Object
  com.esri.arcgis.networkanalyst.NACompactStreetDirectionsAgent

All Implemented Interfaces:

com.esri.arcgis.interop.RemoteObjRef, INAAgent, INACompactStreetDirectionsAgent, INACompactStreetDirectionsAgent2, IPersist, IPersistStream, ISupportErrorInfo, Externalizable, Serializable

public class NACompactStreetDirectionsAgent
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, INAAgent, INACompactStreetDirectionsAgent, INACompactStreetDirectionsAgent2, IPersist, IPersistStream, ISupportErrorInfo, Externalizable

Generates compact driving directions for network analysis results.

Remarks

The NACompactStreetDirectionsAgent object generates driving directions on a route or multiple routes. It generates directions that contain less information and compressed geometries representing the traversed streets. Due to their smaller size, these directions are better suited for passing across low bandwidth connections in server applications. To return these directions using NAServer, rather than using this object directly, set the property INAServerRouteParams2::ReturnCompactDirections or INAServerClosestFacilityParams2::ReturnCompactDirections to true.

You get the NACompactStreetDirectionsAgent from the NAContext's list of agents using the name "CompactStreetDirectionsAgent". For example:

Set pStreetAgent = NAContext.Agents.ItemByName("CompactStreetDirectionsAgent")
