RE: [flexcoders] Re: Tools for listing objects
Using a dictionary isnt completely
reliable because the garbage collector will only free up what it needs. If the
window isnt taking too much space the collector may not go ahead and
clean it up for a while. The weak reference only says take it if you
need it but its not guaranteed that if the only reference is weak
that it will disappear immediately. Thats why we trigger garbage
collection by creating a bunch of objects, its to force the GC into
thinking it needs the space for allocation.

Ok, I get it. So, if i were to write a method which forced a bunch
of anonymouse objects to be created, the GC should fire, and i
should be able to tell if it worked? Let me give that a try.

Matt-
Your solutions didnt work for me, I suspect its because all the
children we create/destroy in this app are done via the popup
manager. Regardless how many children we created that way, I'm
always finding that:
this.childDescriptors.toString();
var o:Object = ObjectUtil.getClassInfo(Application.application);
trace(ObjectUtil.toString(o));
and Application.application.getChildren().toString()
return the
same
things, whether there is 0 or 100 windows open. So far, the best
I've found for our needs is:
var childList:IChildList = this.systemManager.rawChildren;
for(var i:int=0;ichildList.numChildren;i++){
trace(childList.getChildAt(i));
}
My fear is that there may be orphans, windows which have been
removed from the display list but which are still active in
memory.
Any idea how to check on that?

currently in existance? We are looking to verify that we have
truely cleaned up objects no longer in use, and released them
to the GC, but without a tool like this, we cant tell what
exists and what doesnt. Does anyone have any tips?

Theres no way to know if garbage

For (var i:int=0; I 1; i++)
New Object();
That should trigger the garbage collector hopefully.

Implying that the screens arent really being destroyed. Perhaps
I
didnt wait long enough, so 5 minutes later, I tried the same
thing,
with the same results. Maybe 5 minutes isnt long enough, so I'll
leave it running over night and try again in the morning. But,
the
fundemental question is, have i done enough to remove the
screens?
Should the garbage collector clean the unused ones up, or have i
somehow left a reference lingering?
We have a very complex app, which I want to ensure we clean up
all
unused objects, but im having trouble finding a way to verify
they
are removed.

[flexcoders] Re: Tools for listing objects
Matt-
Your solutions didnt work for me, I suspect its because all the
children we create/destroy in this app are done via the popup
manager. Regardless how many children we created that way, I'm
always finding that:
this.childDescriptors.toString();
var o:Object = ObjectUtil.getClassInfo(Application.application);
trace(ObjectUtil.toString(o));
and Application.application.getChildren().toString() return the same
things, whether there is 0 or 100 windows open. So far, the best
I've found for our needs is:
var childList:IChildList = this.systemManager.rawChildren;
for(var i:int=0;ichildList.numChildren;i++){
trace(childList.getChildAt(i));
}
My fear is that there may be orphans, windows which have been
removed from the display list but which are still active in memory.
Any idea how to check on that?

[flexcoders] Re: Tools for listing objects
Darn, I've been able to prove to myself that the object can still
exist in memory but not be in the rawchildren. How can i get a
handle on these orphans? Do I need to resort to creating a
Dictionary Object with weak keys, and store an reference of every
object created in there? Is there a more elegant solution?

RE: [flexcoders] Re: Tools for listing objects
Weve been thinking about trying to
expose a tool that would give you an accurate count of objects but its
not something near-term. If the object is not on the display list (not in raw
children) but is still sticking around then you clearly have a reference to it
somewhere. Typically it would be an event listener that wasnt added
with a weak key or something that is referred to by another class that is on
the display list. Unfortunately I dont have a good technique for
finding those L
