Module: ActionDispatchJourneyRouterWithFiltering

Defined in:
lib/routing_filter/adapters/routers/journey.rb

Prepend the method lookup to intercept find_routes in rails.

This enables us to intercept the incoming route paths before they are recognized by the rails router and transformed to a route set and dispatched to a controller.
