OSD_Chronometer Class Reference

This class measures CPU time (both user and system) consumed
by current process or thread. The chronometer can be started
and stopped multiple times, and measures cumulative time.

#include <OSD_Chronometer.hxx>

Public Member Functions
void *	operator new (size_t, void *anAddress)
void *	operator new (size_t size)
void	operator delete (void *anAddress)
	OSD_Chronometer (const Standard_Boolean ThisThreadOnly=Standard_False)
	Initializes a stopped Chronometer.
virtual void	Destroy ()
	~OSD_Chronometer ()
virtual void	Reset ()
	Stops and Reinitializes the Chronometer.
virtual void	Stop ()
	Stops the Chronometer.
virtual void	Start ()
	Starts (after Create or Reset) or restarts (after Stop) the chronometer.
virtual void	Show ()
	Shows the current CPU user and system time on the standard output stream <cout>. The chronometer can be running (laps Time) or stopped.
virtual void	Show (Standard_OStream &os)
	Shows the current CPU user and system time on the output stream <os>. The chronometer can be running (laps Time) or stopped.
void	Show (Standard_Real &UserSeconds)
	Returns the current CPU user time in a variable. The chronometer can be running (laps Time) or stopped.
void	Show (Standard_Real &UserSeconds, Standard_Real &SystemSeconds)
	Returns the current CPU user and system time in variables. The chronometer can be running (laps Time) or stopped.
Static Public Member Functions
static void	GetProcessCPU (Standard_Real &UserSeconds, Standard_Real &SystemSeconds)
	Returns CPU time (user and system) consumed by the current process since its start, in seconds. The actual precision of the measurement depends on granularity provided by the system, and is platform-specific.
static void	GetThreadCPU (Standard_Real &UserSeconds, Standard_Real &SystemSeconds)
	Returns CPU time (user and system) consumed by the current thread since its start. Note that this measurement is platform-specific, as threads are implemented and managed differently on different platforms and CPUs.
