public interface GtfsRelationalDao extends GtfsDao
While GtfsDao has basic methods for retrieving collections of entities and entities by id, GtfsRelationalDao adds some basic methods for retrieving entities using more complex data relations. You can imagine many complex queries that you might perform on GTFS data, most of which will not be included here. These are just some basic relational methods that we use to bootstrap other GTFS classes. To add more complex queries, look at the specific mechanisms provided by classes implementing GtfsRelationalDao and GtfsDao.
