Win32::Win32Timer Class Reference

#include <win32timer.h>

Detailed Description

Win32 implementation of the Time::Timer class.

Uses the QueryPerformanceCounter() functions.

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 Win32::Win32Timer::GetTicks

(

)

const

get current time in ticks

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

A tick is defined as one millisecond (1/1000 seconds).

GetTime()

Timing::Time Win32::Win32Timer::GetTime

(

)

const

get current time in seconds

This returns the timer's current time in seconds.

InternalTime()

__int64 Win32::Win32Timer::InternalTime ( ) const

private

return internal time as 64 bit integer

This returns the internal local time as large integer.

Reset()

void Win32::Win32Timer::Reset

(

)

reset the timer

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

Running()

bool Win32::Win32Timer::Running

(

)

const

return true if currently running

Returns true if the timer is currently running.

Start()

void Win32::Win32Timer::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 Win32::Win32Timer::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.
