OSD_Timer Class Reference

Working on heterogeneous platforms
we need to use the system call gettimeofday.
This function is portable and it measures ELAPSED
time and CPU time in seconds and microseconds.
Example: OSD_Timer aTimer;
aTimer.Start(); // Start the timers (t1).
..... // Do something.
aTimer.Stop(); // Stop the timers (t2).
aTimer.Show(); // Give the elapsed time between t1 and t2.
// Give also the process CPU time between
// t1 and t2.

#include <OSD_Timer.hxx>

Public Member Functions
DEFINE_STANDARD_ALLOC	OSD_Timer ()
	Builds a Chronometer initialized and stopped.
virtual void	Reset ()
	Stops and reinitializes the timer.
virtual void	Show ()
	Shows both the elapsed time and CPU time on the standard output stream <cout>.The chronometer can be running (Lap Time) or stopped.
virtual void	Show (Standard_OStream &os)
	Shows both the elapsed time and CPU time on the output stream <OS>.
void	Show (Standard_Real &seconds, Standard_Integer &minutes, Standard_Integer &hours, Standard_Real &CPUtime)
	returns both the elapsed time(seconds,minutes,hours) and CPU time.
virtual void	Stop ()
	Stops the Timer.
virtual void	Start ()
	Starts (after Create or Reset) or restarts (after Stop) the Timer.
Standard_Real	ElapsedTime ()
	Returns elapsed time in seconds.
