Posix::PosixTimer Class Reference

#include <posixtimer.h>

Detailed Description

Posix implementation of the Time::Timer class.

Under Posix, time measurement uses the QueryPerformanceCounter() methods.

Todo

solve multiprocessor issues of QueryPerformanceCounter() (different processors may return different PerformanceFrequency values, thus, threads should be prevented from switching between processors with thread affinities).

constructor

Member Function Documentation

GetTicks()

Timing::Tick Posix::PosixTimer::GetTicks

(

)

const

get current time in ticks

This returns the timer's current time in "ticks".

GetTime()

Timing::Time Posix::PosixTimer::GetTime

(

)

const

get current time in seconds

This returns the timer's current time in seconds.

InternalTime()

Timing::Time Posix::PosixTimer::InternalTime ( ) const

private

return internal time

This returns the internal local time as large integer.

Reset()

void Posix::PosixTimer::Reset

(

)

reset the timer

Reset the timer so that will start counting at zero again.

Running()

bool Posix::PosixTimer::Running

(

)

const

return true if currently running

Returns true if the timer is currently running.

Start()

void Posix::PosixTimer::Start

(

)

start/continue the timer

Start the timer.

This will update the diffTime member to reflect the accumulated time when the timer was not running (basically the difference between this timer's time and the real system time).

Stop()

void Posix::PosixTimer::Stop

(

)

stop the timer

Stop the timer.

This will record the current realtime, so that the next Start() can measure the time lost between Stop() and Start() which must be taken into account to keep track of the difference between this timer's time and realtime.

ToTime()

Timing::Time Posix::PosixTimer::ToTime ( const timespec & ts ) const

private

Convert timespec to Timing::Time.
