Detailed Description

Class for simple performance measurements.

Holds a reference start time and allows to retrieve the time elapsed since that time

Member Typedef Documentation

DurationType

typedef double iAPerformanceTimer::DurationType

the time resolution type to use

Constructor & Destructor Documentation

iAPerformanceTimer()

iAPerformanceTimer::iAPerformanceTimer

(

)

Create a performance helper.

Records the start time just as start() does

~iAPerformanceTimer()

iAPerformanceTimer::~iAPerformanceTimer

(

)

destructor

Member Function Documentation

elapsed()

iAPerformanceTimer::DurationType iAPerformanceTimer::elapsed

(

)

const

retrieve the time elapsed since the reference start time

start()

void iAPerformanceTimer::start

(

)

Sets the reference start time.

Only needed if measurement should start at a time after construction (as constructor already sets it), or if class is reused to time multiple events

Member Data Documentation

DurationSecondFactor

const double iAPerformanceTimer::DurationSecondFactor = 1000000.0

static

factor for how many counts are one second Has to match the DurationType!
