Detailed Description

Timer Class

Definition at line 30 of file timer.h.

Constructor & Destructor Documentation

BALL::Timer::Timer

(

)

Default constructor. Create a new timer. The timer is stopped.

BALL::Timer::Timer

(

Timer &

timer

)

Copy constructor. Create a new timer from an existing timer.

virtual BALL::Timer::~Timer ( )

virtual

Destructor. Destructs a timer object.

Member Function Documentation

void BALL::Timer::clear

(

)

Starting, Stopping and Resetting the timer Clear and stop the timer. This sets the timer to zero and stops it when running.

See Also

reset

void BALL::Timer::dump	(	::std::ostream &	s = ::std::cout,
		Size	depth = 0L
	)		const

Dump the timer's contents.

double BALL::Timer::getClockTime

(

)

const

Get clock time. Return the accumulated clock (real) time in seconds.

BALL_INLINE double BALL::Timer::getCPUTime

(

)

const

Get CPU time. Return the accumulated CPU time in seconds. CPU time is the sum of user time and system time.

Definition at line 20 of file timer.h.

double BALL::Timer::getSystemTime

(

)

const

Get user time. Return the accumulated system time in seconds.

double BALL::Timer::getUserTime

(

)

const

Get user time. Return the accumulated user time in seconds.

BALL_INLINE bool BALL::Timer::isRunning

(

)

const

Return true if the timer is running.

Returns

bool true if the timer is running, false otherwise

Definition at line 14 of file timer.h.

BALL_INLINE bool BALL::Timer::isValid

(

)

const

Test if the instance is valid. Allways returns true.

Definition at line 8 of file timer.h.

BALL_INLINE bool BALL::Timer::operator!=

(

const Timer &

timer

)

const

Inequality operator. Return false if two timers differ in any way, i.e. they differ in either the clock, user, or system time or have a different running status.

Parameters

timer

the timer to compare with

Returns

bool true on inequality, false otherwise

Definition at line 26 of file timer.h.

BALL_INLINE bool BALL::Timer::operator<

(

const Timer &

timer

)

const

Lesser than operator. Return true, if the timer is in all timings lesser than the timer to be compared with (clock, user and system time).

Parameters

timer

the timer to compare with

Returns

bool true if all times are lesser

Definition at line 32 of file timer.h.

BALL_INLINE bool BALL::Timer::operator<=

(

const Timer &

timer

)

const

Lesser or equal operator. Return true, if the timer is in all timings lesser or equal than the timer to be compared with (clock, user and system time).

Parameters

timer

the timer to compare with

Returns

bool true if all times are lesser or equal

Definition at line 44 of file timer.h.

Timer& BALL::Timer::operator=

(

const Timer &

timer

)

Assignment operator. Assigns a timer from another. The two timer will then run synchronously.

Returns

Timer *this

bool BALL::Timer::operator==

(

const Timer &

timer

)

const

Equality operator. Return true if two timers are equal, i.e. they contain exactly the same time intervals for clock, user and system time and have the same running status.

Parameters

timer

the timer to compare with

Returns

bool true on equality, false otherwise

BALL_INLINE bool BALL::Timer::operator>

(

const Timer &

timer

)

const

Greater operator. Return true, if the timer is in all timings greater than the timer to be compared with (clock, user and system time).

Parameters

timer

the timer to compare with

Returns

bool true if all times are greater

Definition at line 38 of file timer.h.

BALL_INLINE bool BALL::Timer::operator>=

(

const Timer &

timer

)

const

Greater or equal operator. Return true, if the timer is in all timings greater or equal than the timer to be compared with (clock, user and system time).

Parameters

timer

the timer to compare with

Returns

bool true if all times are greater or equal

Definition at line 50 of file timer.h.

void BALL::Timer::reset

(

)

Clear the timer without stopping. The timer is cleared, but not stopped (if running).

See Also

clear

bool BALL::Timer::start

(

)

Start the timer. The timer is started. If the timer is already running, false is returned.

Returns

bool false if the timer was already running, true otherwise

bool BALL::Timer::stop

(

)

Stop the timer. The timer is stopped. If the timer was not running, false is returned.

Returns

bool false if the was not running, true otherwise
