use of org.onebusaway.transit_data_federation.services.transit_graph.RouteEntry in project onebusaway-application-modules by camsys.

the class GtfsRealtimeEntitySource method getRouteId.

/**
 * Given a route id without an agency prefix, we attempt to find a
 * {@link RouteEntry} with the specified id by cycling through the set of
 * agency ids specified in {@link #setAgencyIds(List)}. If a
 * {@link RouteEntry} is found, we return the id of the parent
 * {@link RouteCollectionEntry} as the matching id. This is to deal with the
 * fact that while GTFS deals with underlying routes, internally OneBusAway
 * mostly deals with RouteCollections.
 *
 * If no route is found in the {@link TransitGraphDao} with the specified id
 * for any of the configured agencies, a {@link Id} will be constructed with
 * the first agency id from the agency list.
 *
 * @param routeId
 * @return an Id for {@link RouteCollectionEntry} with a matching
 *         {@link RouteEntry} id
