Detailed Description

Timer.

Timer.

Examples

testsuite/ftp.cpp, testsuite/http.cpp, and testsuite/ping.cpp.

Constructor & Destructor Documentation

Timer()

Timer::Timer ( )

inlinenoexcept

Initializes the timer. The timer is started.

Member Function Documentation

getLiveMicroseconds()

uint64 Timer::getLiveMicroseconds ( ) const

inlinenoexcept

Returns the number of elapsed microseconds since start.

Examples

testsuite/ftp.cpp, and testsuite/http.cpp.

getMeasureFrequency()

static uint64 Timer::getMeasureFrequency ( )

staticnoexcept

Measure frequency (ticks per second).

getMicroseconds()

uint64 Timer::getMicroseconds ( ) const

inlinenoexcept

Returns the number of elapsed microseconds between start and stop times.

Examples

testsuite/ping.cpp.

getNow()

static uint64 Timer::getNow ( )

staticnoexcept

Returns the current time in microseconds.

getNowNS()

static uint64 Timer::getNowNS ( )

staticnoexcept

Returns the current time in nanoseconds.

getRealNow()

static uint64 Timer::getRealNow ( )

staticnoexcept

Returns the current clock time in microseconds. Time can go backwards.

getStartTime()

uint64 Timer::getStartTime ( ) const

inlinenoexcept

Returns the start time in microseconds.

getStopTime()

uint64 Timer::getStopTime ( ) const

inlinenoexcept

Returns the stop time in microseconds.

start()

void Timer::start ( )

inlinenoexcept

Starts the timer.

Examples

testsuite/http.cpp, and testsuite/ping.cpp.

stop()

void Timer::stop ( )

inlinenoexcept

Stops the timer.

Examples

testsuite/ping.cpp.

toTimeNS()

static uint64 Timer::toTimeNS ( XTime  time )

staticnoexcept

Converts XTime to normal 64-bit time (nanoseconds).

toTimeUS()

static uint64 Timer::toTimeUS ( XTime  time )

staticnoexcept

Converts XTime to normal 64-bit time (microseconds).

toXTimeNS()

static XTime Timer::toXTimeNS ( uint64  nanoseconds )

staticnoexcept

Returns XTime from nanoseconds.

toXTimeUS()

static XTime Timer::toXTimeUS ( uint64  microseconds )

staticnoexcept

Returns XTime from microseconds.
