I've hit a few places in the past and will attempt to drudge them up, but no
warranties here.
How about a case where you create a timer as a local variable in a function
and add a weak listener. Since there are no strong references to the Timer I
beilieve it is eligible for garbage colleciton, and I'm pretty sure I've
seen that problem more than once.
public function setTimer():void
{
var timer:Timer = new Timer(15000);
timer.addEventListener(TimerEvent.TIMER,timerFired,false,0,true);
}
public function timerFired(event:TimerEvent):void
{
//May never get called because Timer could be garbage collected before
firing
}
I think the safest way to do the above if you don't want to declare timer as
a member variable of the class is to use a strong reference and clean it up
public function setTimer():void
{
var timer:Timer = new Timer(15000);
timer.addEventListener(TimerEvent.TIMER,timerFired);
}
public function timerFired(event:TimerEvent):void
{
event.target.removeEventListener(TimerEvent.TIMER,timerFired);
//Yay! Should also make it here!
}
Typed that in GMail and unverified, as stated above, but may get the
conversation started at least
