virtual	~DtSnapshotManager ()
virtual bool	init ()
virtual void	tick ()
virtual void	setSimTime (double)
	Sets current simulation time so internal variable for heartbeat and snapshot can be initialized appropriately.

	Default is disabled.
virtual bool	periodicSnapshotsEnabled () const
virtual void	setSnapshotPeriod (double period)
	Default is 1 second.

virtual DtInMemorySnapshot *	takeSnapshot (bool isPeriodic=false, bool makeBase=false)
	Snapshots at the current point.
virtual void	clearOutStaleSnapshots ()
	Clears out snapshots that are not within the window of snapshot keeping.
virtual DtInMemorySnapshot *	snapshotFor (int id) const
	Returns the in memory snapshot for this id.
virtual void	setSnapshotHeartbeatTime (double d)
	Sets the tim to send out all the snapshots. Default is 2 seconds or the periodic snapshot time, whichever is greater.
virtual double	snapshotHeartbeatTime () const
virtual void	sendCurrentSnapshots ()
	Sends the current snapshots out.
virtual bool	saveSnapshot (const DtFilename &saveFolder, DtCompressedFileTransporter &tr, DtIfSaveScenario *msg, const DtScenario &currentScenario, const DtSimulationAddress &requestor)
	Saves the closest snapshot of the given sim time to save.
virtual DtInMemorySnapshot *	snapshotClosestToSimTime (double simTime) const
	Returns the snapshot closest to the given sim time.
virtual void	removeSnapshotsAfter (double simTime)
	Removes all snapshots after the given simulation time.
virtual bool	hasSnapshots () const
	Returns true if there are snapshots in the manager.
virtual void	clearAllSnapshots ()
	Clears out all snapshots. If there is no scenario loaded also closes terrain.

virtual bool DtSnapshotManager::init ( )

virtual

virtual void DtSnapshotManager::tick ( )

virtual

virtual void DtSnapshotManager::setSimTime ( double  )

virtual

Sets current simulation time so internal variable for heartbeat and snapshot can be initialized appropriately.

virtual void DtSnapshotManager::enablePeriodicSnapshots ( bool  flag )

virtual

Default is disabled.

virtual bool DtSnapshotManager::periodicSnapshotsEnabled ( ) const

virtual

virtual void DtSnapshotManager::setSnapshotPeriod ( double  period )

virtual

Default is 1 second.

virtual double DtSnapshotManager::snapshotPeriod ( ) const

virtual

virtual void DtSnapshotManager::setNumberOfSnapshotsToKeep ( int  )

virtual

Number of periodic snapshots to keep around. 0 means keep all.

virtual int DtSnapshotManager::numberOfSnapshotsToKeep ( ) const

virtual

virtual void DtSnapshotManager::setPauseCleanup ( bool  )

virtual

Pauses cleanup of snapshotss.

Use when rolling back just to be sure the rollback snapshot is not mistakenly cleaned up

bool DtSnapshotManager::pauseCleanup ( ) const

inline

virtual void DtSnapshotManager::clear ( bool  allButBase = false )

virtual

virtual DtInMemorySnapshot* DtSnapshotManager::takeSnapshot ( bool  isPeriodic = false, bool  makeBase = false  )

virtual

Snapshots at the current point.

Will not effect the periodic snapshot timing. If makeBase is true makes this snapshot the new "base" snapshot (which is one the front-end can rewind to by a single click). If makeBase is true and periodic is also true, periodic will be turned to non-periodic

virtual void DtSnapshotManager::clearOutStaleSnapshots ( )

virtual

Clears out snapshots that are not within the window of snapshot keeping.

virtual DtInMemorySnapshot* DtSnapshotManager::snapshotFor ( int  id ) const

virtual

Returns the in memory snapshot for this id.

virtual

Sets the tim to send out all the snapshots. Default is 2 seconds or the periodic snapshot time, whichever is greater.

virtual double DtSnapshotManager::snapshotHeartbeatTime ( ) const

virtual

virtual void DtSnapshotManager::sendCurrentSnapshots ( )

virtual

Sends the current snapshots out.

virtual

Saves the closest snapshot of the given sim time to save.

If none exists returns false.

virtual DtInMemorySnapshot* DtSnapshotManager::snapshotClosestToSimTime ( double  simTime ) const
