edu.ucdavis.cstars.client.tasks.ClosestFacilityTask

public class ClosestFacilityTask
extends com.google.gwt.core.client.JavaScriptObject

Helps you find closest facilities around any location (incident) on a network. When finding closest facilities, you can specify how many to find and whether the direction of travel is toward or away from them. Once you've found the closest facilities, you can display the best route to or from them, return the travel cost for each route, and display directions to each facility. You can also specify a cutoff cost beyond which ArcGIS Network Analyst should not search for a facility. For instance, you can set up a closest facility problem to search for hospitals within a 15-minute drive time of the site of an accident. Any hospitals that take longer than 15 minutes to reach will not be included in the results. Note: ClosestFacilityTask, and other closest facility related classes, requires ArcGIS Server 10.0 or above and a "closest facility" layer. A closest facility layer is a layer of type esriNAServerClosestFacilityLayer.
