org.deltava.dao.GetOnlineTrack

public class GetOnlineTrack
extends DAO

A Data Access Object to load VATSIM/IVAO data tracks. This DAO can load from the ONLINE_TRACKS table in each Airline's database, which stores track data already associated with a Flight Report. It can also load "raw" metadta from the online track database which contains information for all Airlines populated from the ServInfo feed by the OnlineTrackTask scheduled task.
