Constructor & Destructor Documentation
Default constructor. Create a new timer. The timer is stopped.
Copy constructor. Create a new timer from an existing timer.
Destructor. Destructs a timer object.
Member Function Documentation
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
Dump the timer's contents.
Get clock time. Return the accumulated clock (real) time in seconds.
Get CPU time. Return the accumulated CPU time in seconds. CPU time is the sum of user time and system time.
Get user time. Return the accumulated system time in seconds.
Get user time. Return the accumulated user time in seconds.
Return true if the timer is running.
- Returns:
- bool true if the timer is running, false otherwise
Test if the instance is valid. Allways returns true.
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
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
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
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
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
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
Clear the timer without stopping. The timer is cleared, but not stopped (if running).
- See also:
- clear
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
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
