Detailed Description

A simple start/stop watch with high resolution.

Accumulates the number of passed microseconds while runnning.

Note

This timer needs to be started manually.

Constructor & Destructor Documentation

StartStopHR()

crawlservpp::Timer::StartStopHR::StartStopHR ( )

inline

Constructor initializing the values.

Note

Other than Timer::Simple and Timer::SimpleHR, this timer will not be started automatically on creation.

Member Function Documentation

clear()

void crawlservpp::Timer::StartStopHR::clear ( )

inline

Resets the internal state of the timer.

References duration, and timePoint.

reset()

void crawlservpp::Timer::StartStopHR::reset ( )

inline

Resets the timer.

Warning

The number of microseconds stored internally will be lost.

References duration, and timePoint.

start()

void crawlservpp::Timer::StartStopHR::start ( )

inline

Starts the timer.

Microseconds will be accumulated starting from now on.

If the timer is already running, it will first be stopped, i.e. the number of microseconds stored internally will be refreshed.

stop

References crawlservpp::Helper::DateTime::now(), stop(), and timePoint.

stop()

void crawlservpp::Timer::StartStopHR::stop ( )

inline

Stops the timer.

The number of microseconds stored internally will be refreshed.

start

References duration, crawlservpp::Helper::DateTime::now(), and timePoint.

Referenced by start(), and totalStr().

totalStr()

std::string crawlservpp::Timer::StartStopHR::totalStr ( )

inline

Gets the total duration as formatted string.

If the timer is currenty running, it will first be stopped, i.e. the number of microseconds passed will be refreshed.

Returns

The number of microseconds stored internally, formatted as string.

References duration, crawlservpp::Helper::DateTime::microsecondsToString(), stop(), and timePoint.

Member Data Documentation

duration

std::chrono::high_resolution_clock::duration crawlservpp::Timer::StartStopHR::duration

protected

Duration of previous runs.

Equals std::chrono::high_resolution_clock::duration::zero() if no time has been measured yet (excluding the current run).

Referenced by clear(), reset(), stop(), and totalStr().

timePoint

std::chrono::high_resolution_clock::time_point crawlservpp::Timer::StartStopHR::timePoint

protected

(Time) point of start.

Equals std::chrono::high_resolution_clock::time_point::min() if the timer has not been started yet or is currently stopped.

Referenced by clear(), reset(), start(), stop(), and totalStr().
