use of org.opentripplanner.routing.core.StateEditor in project OpenTripPlanner by opentripplanner.

the class StreetBikeRentalLink method traverse.

Example 2 with StateEditor

use of org.opentripplanner.routing.core.StateEditor in project OpenTripPlanner by opentripplanner.

the class StreetTransitLink method traverse.
