DirectionsQuery

Summary

Provides access to directions properties and query methods.

Discussion

A DirectionsQuery object is provided as a parameter to the customize method, allowing access to the output directions traversed junctions and traversed edges. The direction points associated with these elements can be accessed allowing them to be customized.
