static

virtual void makVrf::DtVrfCheckpointManager::requestSnapshots ( const DtSimulationAddress & addr = DtSimSendToAll )

virtual

Requests snapshots from specified back-end. Request will clear out current map (if DtSimSendToAll) and replace with new information.

virtual void makVrf::DtVrfCheckpointManager::schedulePeriodicSnapshoting	(	bool	enabled,
		double	simTime,
		int	numberOfSnapshotsToKeep
	)

virtual

Enables/disables periodic snapshoting at the specified time interval and save window (in number of snapshots, 0 means all)

virtual void makVrf::DtVrfCheckpointManager::processSnapshotsResponse ( DtSimMessage * )

virtual

virtual bool makVrf::DtVrfCheckpointManager::rollbackTo ( double simTime = -1 )

virtual

Rolls back to given snapshot, or, if snapshot is -1, last snapshot. Returns true if snapshot exists.

virtual bool makVrf::DtVrfCheckpointManager::haveSnapshotsThatCanBeRolledBack ( ) const

virtual

Returns true if there are any snapshots that can be rolled back to.

virtual void makVrf::DtVrfCheckpointManager::clearSnapshots ( )

virtual

Signals to clear out all snapshots.

virtual bool makVrf::DtVrfCheckpointManager::saveCheckpoints ( const std::set< double > & )

virtual

Given a list of sim times to save as an on disk checkpoint, send a message to queue them up to be saved.

virtual bool makVrf::DtVrfCheckpointManager::saveCheckpoint ( double )

virtual

virtual bool makVrf::DtVrfCheckpointManager::saveCheckpoints ( )

virtual

Saves all snapshots for currently unsaved snapshot states.

virtual bool makVrf::DtVrfCheckpointManager::takeSnapshot ( bool force = false )

virtual

Creates a snapshot at the current sim clock time and returns whether or not this scenario is saved on disk. If there is already a snapshot do not send snapshot again unless force is true.

virtual bool makVrf::DtVrfCheckpointManager::takeBaseSnapshot ( )

virtual

Makes this snapshot the new base snapshot.

virtual bool makVrf::DtVrfCheckpointManager::snapshotFor	(	double	simTime,

	)		const

virtual

Returns the available snapshot (if exists) at sim time.

virtual bool makVrf::DtVrfCheckpointManager::hasBaseSnapshot ( double simTime = -1 ) const

virtual

Returns true if has a base snapshot at sim time. If sim time is -1, looks for any base snapshot.

virtual bool makVrf::DtVrfCheckpointManager::hasSnapshot ( double simTime ) const

virtual

Returns true if there is a snapshot at the specified sim time.

virtual bool makVrf::DtVrfCheckpointManager::hasFixedSnapshot ( double simTime ) const

virtual

Returns true if there is a non periodic snapshot at the given sim time.

virtual bool makVrf::DtVrfCheckpointManager::hasPeriodicSnapshot ( double simTime ) const

virtual

Returns true if there is a periodic snapshot at the given sim time.

virtual bool makVrf::DtVrfCheckpointManager::hasSavedScenarioForSnapshot ( double simTime ) const

virtual

Returns true if the snapshot at the sim time has been saved.

virtual bool makVrf::DtVrfCheckpointManager::hasUnaskedUnsavedSavedScenarioForSnapshot ( double simTime ) const

virtual

Has an unasked unsaved snapshot at the given sim time.

virtual bool makVrf::DtVrfCheckpointManager::isSavingCheckpoints ( ) const

virtual

Returns true if there are items scheduled to save.

virtual void makVrf::DtVrfCheckpointManager::setAskedToSaveAtThisSimTime	(	double	simTime,

Convert sim time to a time that can be snapshoted to.

virtual void makVrf::DtVrfCheckpointManager::setScenarioAsSaved ( const DtFilename & )

virtual

If there is a snapshot at the sim time of this scenario, set it as saved.

virtual void makVrf::DtVrfCheckpointManager::clearAllSnapshots ( )

virtual

Sends message to clear all snapshots from all back-ends.

virtual double makVrf::DtVrfCheckpointManager::firstLoadableSimTime ( ) const

The time that will be shown as the "base" snapshot (the snapshot that when rewinding to beginning will set to)

virtual void makVrf::DtVrfCheckpointManager::updateCheckpointsSavedStatus ( )

virtual

Goes through all checkpoints and updates their saved status. Any that have changed will be signalled out as added/removed from save.
