This class represents a routing algorithm that is based on the A* algorithm.

The A* algorithm is one of the best graph search algorithms that finds the least-cost path from a given start point to a given end point. It uses a distance-plus-cost heuristic function to determine the order in which the search visits routeSegments in the data.

• System.Object
