public class ServiceValidator
extends TripValidator

This will validate that service date information is coherent, and attempt to deduce or validate the range of dates covered by a GTFS feed. It turns the GTFS system of repeating weekly calendars and exceptions (calendar dates) into a single large table listing which services run on which days. This in turn allows us to build a histogram of service duration on each day. As an intermediate result it builds a table of service duration by service ID and mode of transport. Makes one object representing each service ID. That object will contain a calendar (for repeating service on specific days of the week) and potentially multiple CalendarDates defining exceptions to the base calendar. TODO build histogram of stop times, check against calendar and declared feed validity dates

                         List<StopTime> stopTimes,

Description copied from class: TripValidator

This method will be called on each trip in the feed.

Specified by:

validateTrip in class TripValidator

Parameters:

trip - the trip whose stop_times are provided in the other parameter.

stopTimes - a List of all the stop times in the given trip, in order of increasing stop_sequence.

complete

public void complete(ValidationResult validationResult)

You'd think we'd want to do this during the loading phase. But during the loading phase we don't have a reading connection to the entity tables in the database. Rather than make the Feed object read-write, we want to leave it completely read-only.

Overrides:

complete in class Validator

Parameters:

validationResult - can be written into
