    • reachable

      public Map<GeoLocation, Duration> reachable(GeoLocation location, LocalTime earliestDeparture, LocalTime latestArrival, TravelDirection direction) throws InterruptedException
      Returns a map of locations reachable within the given time windows, and the corresponding cost of each location's shortest path duration.
      Parameters:
      location - the location, not null
      earliestDeparture - the earliest departure time, not null
      latestArrival - the latest arrival time, not null
      direction - the direction of travel, not null
      Returns:
      an ordered map of reachable locations, with associated costs
      Throws:
      InterruptedException - if the thread is interrupted

    • reachable

      public Map<GeoLocation, Duration> reachable(GeoLocation location, LocalTime earliestDeparture, LocalTime latestArrival, TravelDirection direction, Map<GeoLocation, List<Trip>> extra) throws InterruptedException
      Returns a map of locations reachable within the given time windows, and the corresponding cost of each location's shortest path duration.
      Parameters:
      location - the location, not null
      earliestDeparture - the earliest departure time, not null
      latestArrival - the latest arrival time, not null
      direction - the direction of travel, not null
      extra - additional trips to be included, ignored if null or empty
      Returns:
      an ordered map of reachable locations, with associated costs
      Throws:
      InterruptedException - if the thread is interrupted

      earliestDeparture - the earliest departure time, not null
      latestArrival - the latest arrival time, not null
      direction - the direction of travel, not null
      consumer - a consumer of reachable locations, with associated costs
      Throws:
      InterruptedException - if the thread is interrupted
