Detailed Description

cPrecisionClock provides a class to manage high-precision time measurements. All measurements are in seconds unless otherwise-specified.

Constructor & Destructor Documentation

cPrecisionClock::cPrecisionClock (  ) 

Constructor of cPrecisionClock.

Constructor of cPrecisionClock. Clock is initialized to zero.


Member Function Documentation

long cPrecisionClock::getCPUtime (  )  [inline]

For backwards-compatibility...

If all you want is something that tells you the time, this is your function...

Returns:
Return cpu clock in seconds.

double cPrecisionClock::getCurrentTimeSeconds (  ) 

Read the current clock time (seconds) (the time that has elapsed since the last call to "start").

Read the current time of timer. Result is returned in seconds.

Returns:
Return current time in seconds

void cPrecisionClock::reset ( void   ) 

Reset clock to zero.

Reset the clock to zero.

void cPrecisionClock::setTimeoutPeriodSeconds ( double  a_timeoutPeriod  ) 

Set the period before a "timeout" occurs (you need to poll for this).

Set the period in microseconds before timeout occurs. Do not forget to set the timer on by calling method start()

Parameters:
a_timeoutPeriod Timeout period in seconds.

double cPrecisionClock::start ( bool  a_resetClock = false  ) 

Start counting time; optionally reset the clock to zero.

Start the clock from its current time value. To read the latest time from the clock, use method getCurrentTime.

Parameters:
a_resetClock Should we start counting from zero?
Returns:
Returns the current clock time.

double cPrecisionClock::stop (  ) 

Stop counting time; return the elapsed time.

Stop the timer. To resume counting call start().

Returns:
Return time in seconds.

bool cPrecisionClock::timeoutOccurred (  ) 

Returns true if a timeout has occurred.

Check if timer has expired its timeout period. if so return true.

Returns:
Return true if timeout occurred, otherwise false.
