List of all members.

Public Methods
	timer ()
	Default constructs the timer object.
void	clear ()
	Clears the memory belonging to tms_begin & tms_end and sets elapsed_begin and elapsed_end to 0.
void	start ()
	Starts the timer.
void	stop ()
	Stops the timer.
size_t	real_time () const
	Computes the real time used. This is typically the sum of the user and system times.
size_t	user_time () const
	Computes the user time used. This is the time that the program spends in the user space, executing user space code.
size_t	system_time () const
	Computes the system time used. This is the time that the program spends in the kernel space, executing kernel space code.

Member Function Documentation

void eqn_cruncher::timer::clear (    )  [inline]

Clears the memory belonging to tms_begin & tms_end and sets elapsed_begin and elapsed_end to 0.

size_t eqn_cruncher::timer::real_time (    )  const [inline]

Computes the real time used. This is typically the sum of the user and system times. Returns: The real time.

void eqn_cruncher::timer::start (    )  [inline]

Starts the timer.

void eqn_cruncher::timer::stop (    )  [inline]

Stops the timer.

size_t eqn_cruncher::timer::system_time (    )  const [inline]

Computes the system time used. This is the time that the program spends in the kernel space, executing kernel space code. Returns: The system time.

size_t eqn_cruncher::timer::user_time (    )  const [inline]

Computes the user time used. This is the time that the program spends in the user space, executing user space code. Returns: The user time.
