Constructor & Destructor Documentation

virtual MAKVrExchange::DtFrameTimer::~DtFrameTimer ( )

virtual

Virtual DTOR.

MAKVrExchange::DtFrameTimer::DtFrameTimer ( DtPortalConnection *  portalConn )

protected

CTOR.

Member Function Documentation

static DtFrameTimer* MAKVrExchange::DtFrameTimer::create ( DtPortalConnection *  portalConn )

static

Default creation method for instantiating frame timers.

virtual void MAKVrExchange::DtFrameTimer::markFrameStart ( )

virtual

Tells the timer that a frame is beginning.

virtual void MAKVrExchange::DtFrameTimer::markFrameEnd ( )

virtual

Tells the timer that a frame is ending.

virtual void MAKVrExchange::DtFrameTimer::markStart ( FrameSectionType  section )

virtual

Tells the timer that a frame section is starting.

virtual void MAKVrExchange::DtFrameTimer::markEnd ( FrameSectionType  section )

virtual

Tells the timer that a frame section is ending.

virtual void MAKVrExchange::DtFrameTimer::generateReport ( )

virtual

Generates a report based on the recorded statistics since the last report.

Frame and section times and percentages are averaged over the number of frames elapsed since the last report was generated.

virtual void MAKVrExchange::DtFrameTimer::printFrameStatistics ( )

virtual

Prints the statistics from the last report to DtInfo.

virtual const SectionInfoMap& MAKVrExchange::DtFrameTimer::sectionInfo ( ) const

virtual

Accessor for the section info map (read-only).

Note: Should only be called after a generateReport() call and before the next frame start.

virtual double MAKVrExchange::DtFrameTimer::fps ( ) const

virtual

Accessor for the FPS.

Note: Should only be called after a generateReport() call and before the next frame start.

virtual DtString MAKVrExchange::DtFrameTimer::roundPercent ( double  percent )

protectedvirtual

Converts fraction to percent, rounds to int, & appends %.

Member Data Documentation

DtFrameTimerCreator MAKVrExchange::DtFrameTimer::theFrameTimerCreator

static

Storage for the method used to create the frame timer.

Overridden frame timer creators can be set here in order to use a customized frame timer. Make sure the creator is set here before the broker begins processing messages to ensure it is used.
