anonymous_namespace{framerate_gui.cpp}::PerformanceData Struct Reference

Public Member Functions
	PerformanceData (double expected_rate)
	Initialize a data element with an expected collection rate. More...
void	Add (TimingMeasurement start_time, TimingMeasurement end_time)
	Collect a complete measurement, given start and ending times for a processing block.
void	BeginAccumulate (TimingMeasurement start_time)
	Begin an accumulation of multiple measurements into a single value, from a given start time.
void	AddAccumulate (TimingMeasurement duration)
	Accumulate a period onto the current measurement.
void	AddPause (TimingMeasurement start_time)
	Indicate a pause/expected discontinuity in processing the element.
double	GetAverageDurationMilliseconds (int count)
	Get average cycle processing time over a number of data points.
double	GetRate ()
	Get current rate of a performance element, based on approximately the past one second of data.

Data Fields
TimingMeasurement	durations [NUM_FRAMERATE_POINTS]
	Time spent processing each cycle of the performance element, circular buffer.
TimingMeasurement	timestamps [NUM_FRAMERATE_POINTS]
	Start time of each cycle of the performance element, circular buffer.
double	expected_rate
	Expected number of cycles per second when the system is running without slowdowns.
int	next_index
	Next index to write to in durations and timestamps.
int	prev_index
	Last index written to in durations and timestamps.
int	num_valid
	Number of data points recorded, clamped to NUM_FRAMERATE_POINTS.
TimingMeasurement	acc_duration
	Current accumulated duration.
TimingMeasurement	acc_timestamp
	Start time for current accumulation cycle.

Static Public Attributes
static const TimingMeasurement	INVALID_DURATION = UINT64_MAX
	Duration value indicating the value is not valid should be considered a gap in measurements.

Constructor & Destructor Documentation

PerformanceData()

anonymous_namespace{framerate_gui.cpp}::PerformanceData::PerformanceData ( double  expected_rate )

inlineexplicit

Initialize a data element with an expected collection rate.

Parameters

expected_rate

Expected number of cycles per second of the performance element. Use 1 if unknown or not relevant. The rate is used for highlighting slow-running elements in the GUI.
