Example 36 with TripPattern

use of org.opentripplanner.routing.edgetype.TripPattern in project OpenTripPlanner by opentripplanner.

the class GraphIndex method stopTimesForStop.

/**
 * Fetch upcoming vehicle departures from a stop.
 * It goes though all patterns passing the stop for the previous, current and next service date.
 * It uses a priority queue to keep track of the next departures. The queue is shared between all dates, as services
 * from the previous service date can visit the stop later than the current service date's services. This happens
 * eg. with sleeper trains.
 *
 * TODO: Add frequency based trips
 * @param stop Stop object to perform the search for
 * @param startTime Start time for the search. Seconds from UNIX epoch
 * @param timeRange Searches forward for timeRange seconds from startTime
 * @param numberOfDepartures Number of departures to fetch per pattern
 * @param omitNonPickups If true, do not include vehicles that will not pick up passengers.
 * @return
