Timers allow callbacks to be made at a specific time in the future. They are ordinarily created via TimerList methods, and they must be associated with an TimerList object in order to be runnable.

bool scheduled ()
| scheduled |
[const]
Returns: true if the timer has been scheduled, and the callback associated with this timer has not been called yet.
const TimeVal& expiry ()
| expiry |
[const]
Returns: the expiry time of the XorpTimer
bool time_remaining (TimeVal& remain)
| time_remaining |
[const]
Get the remaining time until the timer expires.
Parameters:
remain | the return-by-reference value with the remaining time until the timer expires. If the current time is beyond the expire time (e.g., if we are behind schedule with the timer processing), the return time is zero. |
Returns: true if the remaining time has meaningful value (e.g., if timer was scheduled), otherwise false.
void schedule_now (int priority = XorpTask::PRIORITY_DEFAULT)
| schedule_now |
Expire the XorpTimer object when the TimerList is next run.
void schedule_at (const TimeVal& when,
int priority = XorpTask::PRIORITY_DEFAULT)
| schedule_at |
Schedule the XorpTimer object at a given time.
void schedule_after (const TimeVal& wait,
int priority = XorpTask::PRIORITY_DEFAULT)
| schedule_after |
Schedule the XorpTimer object to expire in wait after the current time.
void schedule_after_ms (int ms,
int priority = XorpTask::PRIORITY_DEFAULT)
| schedule_after_ms |
Schedule the XorpTimer object.
Parameters:
ms | milliseconds from the current time. |
void reschedule_after (const TimeVal& wait)
| reschedule_after |
Reschedule the XorpTimer object.
Parameters:
wait | time from the most recent expiry. |
void reschedule_after_ms (int ms)
| reschedule_after_ms |
Reschedule the XorpTimer object.
Parameters:
ms | milliseconds from the most recent expiry. |
void unschedule ()
| unschedule |
Unschedule the XorpTimer object. The XorpTimer callback is not invoked.
void clear ()
| clear |
Release reference to underlying state.
