Remarks
NAHierarchySettings specify if a particular network analyst solver should use a hierarchy. For example, the route, closest facility, OD matrix, and VRP solvers can use hierarchy if it is present in the network. The hierarchy can be used to solve quickly on large networks by modifying the shortest path solver to look at the road hierarchy and favor the higher level roads to reach the destination. This interface specifies how the values stored in a hierarchy attribute are mapped to the solver needs.
