Member Function Documentation

DtSnapshotManager& DtSnapshotManager::operator= ( const DtSnapshotManager & )

private

Not implemented.

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 bool DtSnapshotManager::isBaseSnapshot ( DtInMemorySnapshot * ) const

virtual

Returns true if this is the base snapshot.

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::rollbackToSimTime ( double simTime )

virtual

Rolls back the snapshot to the current simulation time. Note that this is only good for this cgf. In a multiple cgf environment calling this method will have unpredictable, and possibly buggy, results.

virtual void DtSnapshotManager::rollbackTo	(	DtInMemorySnapshot *	,
		int	scenarioRunId = `0`
	)

virtual

Rolls back to the given in memory snapshot. If supplied, the new scenario run id.

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 void DtSnapshotManager::setSnapshotHeartbeatTime ( double d )

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 bool DtSnapshotManager::saveSnapshot	(	const DtFilename &	saveFolder,
		DtCompressedFileTransporter &	tr,
		DtIfSaveScenario *	msg,
		const DtScenario &	currentScenario,
		const DtSimulationAddress &	requestor
	)

virtual

Saves the closest snapshot of the given sim time to save. If none exists returns false.

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

virtual

Returns the snapshot closest to the given sim time.

virtual void DtSnapshotManager::removeSnapshotsAfter ( double simTime )

virtual

Removes all snapshots after the given simulation time.

virtual bool DtSnapshotManager::hasSnapshots ( ) const

virtual

Returns true if there are snapshots in the manager.

virtual void DtSnapshotManager::clearAllSnapshots ( )

virtual

Clears out all snapshots. If there is no scenario loaded also closes terrain.

static void DtSnapshotManager::clearAllSnapshotsCallback	(	DtSimMessage *	,
		void *
	)

staticprotected

Will tell all locally vrf simulated object so be ready for reinitialize, delete all the objects.

		void *	usr
