Abstract interface class to the AIS data service. This service provides access to Automatic Identification System (AIS) data, which is used to track and monitor real world ships. This data can be used to create and simulate clutter entities in a simulation.

Member Function Documentation

virtual bool DtAisDataServiceInterface::isDataLoaded ( ) const

pure virtual

Returns true if AIS data has been loaded.

Implemented in DtAisDataManager.

virtual DtAisDataJob::Ptr DtAisDataServiceInterface::findTracksInArea	(	const DtVertexList &	areaVertices,
		bool	unownedOnly = `true`
	)

pure virtual

Starts a query for all tracks in the specified area. If unownedOnly is true (the default) then only unowned tracks are returned.

Implemented in DtAisDataManager.

virtual DtAisDataJob::Ptr DtAisDataServiceInterface::findTracksInAreaDuringTime	(	const DtVertexList &	areaVertices,
		double	startSimTime,
		double	endSimTime,
		bool	unownedOnly
	)

pure virtual

Starts a query for all tracks in the specified area. If unownedOnly is true (the default) then only unowned tracks are returned.

Implemented in DtAisDataManager.

virtual const DtAisTrack* DtAisDataServiceInterface::trackInfo ( DtMmsi trackId ) const

pure virtual

Returns information for the track with the specified MMSI, or nullptr if it could not be found. Will always return nullptr if isDataLoaded() returns false;.

Implemented in DtAisDataManager.

virtual DtAisDataJob::Ptr DtAisDataServiceInterface::requestOwnershipOfTracks ( const DtMmsiSet & trackIds )

pure virtual

Request ownership of the specified given tracks.

Implemented in DtAisDataManager.

virtual DtAisDataJob::Ptr DtAisDataServiceInterface::releaseOwnershipOfTracks ( const DtMmsiSet & trackIds )

pure virtual

Release ownership of the specified tracks.

Implemented in DtAisDataManager.

virtual double DtAisDataServiceInterface::aisTimeFromSimTime ( double simTime ) const

pure virtual

Converts a sim time to AIS data time. Needed to understand how sim time relates to the timestamps in the AIS track data.

Implemented in DtAisDataManager.

virtual double DtAisDataServiceInterface::simTimeFromAisTime ( double aisTime ) const

pure virtual

Converts the AIS data time to sim time. Needed to understand how sim time relates to the timestamps in the AIS track data.

Implemented in DtAisDataManager.

virtual double DtAisDataServiceInterface::finalDataSimTime ( ) const

pure virtual

Returns the sim time for the last point of AIS data available.

Implemented in DtAisDataManager.

virtual bool DtAisDataServiceInterface::getFirstPointAfterTime	(	const DtAisTrack &	track,
		double	simTime,
		DtPathPointIter &	pathPointIter
	)		const

pure virtual

Find the first point in the track's path that occurs after (or at) the specified sim time. If no points meet this criteria, returns false and sets pathPointIter to the end of the path. (i.e. path.end()) Otherwise, returns true and pathPointIter parameter is set to the iterator to this point.

Implemented in DtAisDataManager.

virtual bool DtAisDataServiceInterface::getLastPointBeforeTime	(	const DtAisTrack &	track,
		double	simTime,
		DtPathPointIter &	pathPointIter
	)		const

pure virtual

Find the last point in the track's path that occurs before (or at) the specified sim time. If no points meet this criteria, returns false and sets pathPointIter to the end of the path. (i.e. path.end()) Otherwise, returns true and pathPointIter parameter is set to the iterator to this point.

Implemented in DtAisDataManager.

virtual DtPathPointIter DtAisDataServiceInterface::getEndOfpath ( const DtAisTrack & track ) const

pure virtual

Returns an iterator to the end of the path (i.e. path.end()).

Implemented in DtAisDataManager.

virtual void DtAisDataServiceInterface::resetData ( )

pure virtual

Marks AIS data to be reset. Data will not be unloaded, but ownership of all tracks will be reset to unowned.

Implemented in DtAisDataManager.

virtual void DtAisDataServiceInterface::clearData ( )

pure virtual

Marks AIS data to be cleared. Data will be completely unloaded.

Implemented in DtAisDataManager.

DtAisDataServiceInterface& DtAisDataServiceInterface::operator= ( const DtAisDataServiceInterface & )

private

Assignment operator not implemented.
