Example 1 with NonStationParentStation

use of org.opentripplanner.graph_builder.annotation.NonStationParentStation in project OpenTripPlanner by opentripplanner.

the class GTFSPatternHopFactory method linkStopsToParentStations.

/**
 * Links the vertices representing parent stops to their child stops bidirectionally. This is
 * not intended to provide implicit transfers (i.e. child stop to parent station to another
 * child stop) but instead to allow beginning or ending a path (itinerary) at a parent station.
 *
 * Currently this linking is only intended for use in the long distance path service. The
 * pathparsers should ensure that it is effectively ignored in other path services, and even in
 * the long distance path service anywhere but the beginning or end of a path.
