DtScheduler Class Reference

Instances of class DtScheduler maintain a list of DtTimer objects. It ticks all timer objects each time it is ticked. It maintains the DtTimers as a sorted list in order of time to fire, so that once a timer is found that is not ready to fire, none of the others will need to be ticked.

virtual void DtScheduler::tick ( )

virtual

Iterates through list of DtTimers. DtTimers are maintained in chronological order of fire time (sooner to later). If resortIsPending() for a given timer, skips the timer (to be resorted at the end of the tick), otherwise calls the timer's tick() function. If a given timer fires and timer should be deleted upon firing, removes and deletes the timer. At the end of the tick, calls doPendingResorts() to re-sort any timers that require it.

virtual void DtScheduler::addTimer ( DtTimer *  timer )

virtual

None of the DtTimer * arguments are const, since all of these routines may modify the timerMgrEntry field of a DtTimer.

Adds a given timer to the scheduler. Sets a pointer to the instance of the scehduler in the given timer, adds the timer, and then calls resort().

virtual void DtScheduler::removeTimer ( DtTimer *  timer )

virtual

If the given timer is non-null and is managed, looks up and removes the timer, and sets the scheduler to null in the timer.

virtual void DtScheduler::reset ( bool  clearAll = false )

virtual

Removes and deletes out 'deleteAfterFire' timers if clearAll is false. If clearAll is true, removes and deletes 'all' timers.

void DtScheduler::reSort

(

DtTimer *

timer

)

Moves timers that have fired to the end of the list of timers. Sorts timers in order of sooner to later fire time.

void DtScheduler::doPendingResorts ( )

protected

Calls reSort() for any timer for which resortPending() returns true.

void DtScheduler::moveToEnd ( DtTimer *  timer )

protected

Removes timer from its current position and adds it to the end.

Member Data Documentation

bool DtScheduler::myInTick

protected

If in tick, ReSort() does NOT resort. Instead, it marks the timer as resortPending. These timers will be resorted at the end of the tick function.
