Detailed Description

The simulation engine is controlled by a single,top-level class called the Simulation Manager.

All the objects in the simulation backend are owned by the Simulation Manager. The Simulation Manager will be called via a tick() member function once each simulation frame, at which time it will process incoming messages and provide execution control to all the other objects it manages.

Constructor & Destructor Documentation

DtSimManager::DtSimManager ( DtExerciseConn * connection )

constructor

virtual DtSimManager::~DtSimManager ( )

virtual

destructor

DtSimManager::DtSimManager ( const DtSimManager & orig )

private

Copy constructor - not implemented.

Note: This class is not copyable.

Member Function Documentation

DtSimManager& DtSimManager::operator= ( const DtSimManager & orig )

private

Assignment operator - not implemented.

Note: This class is not assignable.

virtual bool DtSimManager::init ( )

virtual

creates all the other pieces.

Note that the object id generator is created and set in the DtVrfObjectIdGenerator class as the default generator to use. If yo have not set a new creator in the factory, reset in the DtVrfObjectIdGenerator class after init() is called

virtual bool DtSimManager::createExerciseClock ( )

virtual

Exercise clock for back-end.

Maintains concept of simulation time, frame rate and the various frame rate modes (variable, fixed-frame best effort, fixed-frame run to complete). If application is HLA13 or HLA1516 (i.e. if DtHLA is defined), creates a clock of type DtHlaExerciseClock. Otherwise, creates a a clock of type DtExerciseClock. DtHlaExerciseClock is extended to include the concept of HLA time management mode. Clock may optionally be configured to enable time regulating and constrained modes. Configurable through the vrfSim.mtl parameter file.

virtual bool DtSimManager::createScheduler ( )

virtual

virtual bool DtSimManager::createMessageInterface ( )

virtual

virtual bool DtSimManager::createFrameRateMonitor ( )

virtual

virtual bool DtSimManager::createVrfSimSettingsManager ( )

virtual

Creates the DtVrfSimSettingsManager.

virtual void DtSimManager::tick ( )

virtual

Ticks the scheduler and then all registered tick callbacks.

Calls sleep().

virtual void DtSimManager::setTargetFrameRate ( int rate )

virtual

The frame rate above which the back-end will call sleep() in order to yield CPU time to other processes.

Once the frame rate drops below this level, the back-end will no longer sleep. This parameter only takes effect when the simulation is running in variable frame mode.

virtual int DtSimManager::targetFrameRate ( ) const

virtual

The frame rate above which the back-end will call sleep() in order to yield CPU time to other processes.

Once the frame rate drops below this level, the back-end will no longer sleep. This parameter only takes effect when the simulation is running in variable frame mode.

virtual void DtSimManager::sleep ( ) const

virtual

Calls DtSleep(0.01) when the simulation is paused or when the mean frame rate is above the frame rate specified by targetFrameRate().

virtual bool DtSimManager::deliverMessage ( const DtSimInterfaceMessage & msg )

virtual

virtual bool DtSimManager::receiveMessage ( const DtSimInterfaceMessage & msg )

virtual

virtual bool DtSimManager::createAndDeliverMessage	(	const DtSimulationAddress &	recipient,
		const DtSimInterfaceContent &	content,
		bool	overrideTimestampOrder = `true`
	)

virtual

virtual void DtSimManager::addTickEntry	(	DtSimTickFunction	tickFunction,
		void *	userData
	)

virtual

Callback that will be called every simulation tick of the system.

Note: DtSimTickFunction was previously (VRF 3.10) a method that took an argument of DtSimTickArguments*, but now takes a void*. This has been changed to make it more consistent with other callbacks in VR-Forces. A special subclass of DtSimTickArguments is no longer required. Simply pass any pointer in when registering the callback, and this same pointer will be passed back to the callback method when it is invoked.

virtual void DtSimManager::removeTickEntry	(	DtSimTickFunction	tickFunction,
		void *	userData
	)

virtual

Callback that will be called every simulation tick of the system.
