ClosestFacilityTask class final
A class that implements the closest facility task.
The closest facility task class uses a transportation network to measure the cost of traveling between incidents and facilities and determines which are nearest to one other. When finding closest facilities, you can specify how many to find and whether the direction of travel is toward or away from them.
