Constructor & Destructor Documentation

DtFrameRateMonitor::DtFrameRateMonitor

(

)

Default constructor; note that if this form is used and a sim manager is not set, reports will not be sent (but console output can still be generated.)

DtFrameRateMonitor::DtFrameRateMonitor

(

DtSimManager *

simManager

)

standard constructor

DtFrameRateMonitor::DtFrameRateMonitor

(

const DtFrameRateMonitor &

orig

)

copy constructor; report timer is currently not copied.

virtual DtFrameRateMonitor::~DtFrameRateMonitor ( )

destructor

Member Function Documentation

const DtFrameRateMonitor& DtFrameRateMonitor::operator=

(

const DtFrameRateMonitor &

orig

)

assignment operator; see copy constructor above.

virtual bool DtFrameRateMonitor::init ( )

virtual

Calls register callbacks.

virtual void DtFrameRateMonitor::setSimManager ( DtSimManager *  simManager )

virtual

If the default constructor was used, you can supply a sim manager later; however, if you do, you must also call registerInterfaceCallbacks().

virtual bool DtFrameRateMonitor::registerInterfaceCallbacks ( )

virtual

Note

Requires that a valid simManager was provided at construction time.

virtual

virtual double DtFrameRateMonitor::maximumFrameRate ( )

virtual

virtual double DtFrameRateMonitor::simTimeToRealTimeRatio ( )

virtual

virtual void DtFrameRateMonitor::addSample ( double  frameTime )

virtual

If the frameTime is > 0, it calculates the current frame rate as 1/frameTime.

Then it adds this frameTime (either 0 or calculated value) to its averager as another sample point.

virtual double DtFrameRateMonitor::lastSample ( ) const

virtual

Returns

The last sample point added. (Should be the last reported value of 1/frameTime).

virtual void DtFrameRateMonitor::reset ( bool  sendReport = false )

virtual

Clear out the array of frame rates and start over.

If sendReport is true, will send out a frame rate report if there are any requestors

virtual void DtFrameRateMonitor::setNumberOfFramesToAverage ( unsigned int  numFramesToAverage )

virtual

Can also be set in a frameRateRequestMessage. A zero turns off averaging.
