I'd like to know for sure that my objects are deleted when I 'null' them and remove listeners etc..
I'm not sure if the debugger in CS4 has a way to display that kind of info. Is there some other way?
Consider the following segment of code:

Do not worry about the syntax of this code. Here is my concern - The loader object which is used to send the HTTP request and which has the onLoadComplete event registered to is not referenced from outside the loadSomeContent() function. Is there a possibility that the loader object will be garbage collected and loadCompleteHandler() will never be called?
I was thinking about Flash GC the other day and came up with a question about how reference counting would work in the following 4 class scenario (assume GuiMain is the movie's document class):
[Code]...
I just noticed a strange behaviour while looking at my application in the Flash Profiler. When I click a button in my TitleWindow then the TitleWindow doesn't get garbage collected after it is removed. I have no idea why that is happening.[code]...
View 2 RepliesI have checked and rechecked, and I do not know why these "buckets" aren't being killed when I run the reset menu function, a fresh set of eyes could really help.
Code:
package com.Views {
import flash.display.MovieClip;
import flash.display.Sprite;
import flash.events.Event;
[Code]...
i'm sure there are a lot of problems, but the only one I care about is destroying those buckets. inside the buckets, I have a listener for "removed from stage", and that kills all the listeners, etc, inside the buckets.
there is a Class A, it has a timer which updates its x position periodically. So all the instance of Class A will update their own x position. There is another Class B which extends Class A and overrides the function which updates position to change y position and call the trace function.
Now what I do now is create two instance alpha1, alpha2 of Class A and other two instance beta1, beta2 of Class B.
- alpha1 is only instantiated, but not added to the stage.
- alpha2 is instantiated, and there after added to the stage.
- beta1 is only instantiated, but not added to the stage.
- beta2 is instantiated, and there after added to the stage.
- let say after few seconds, I remove alpha2 and beta2 from stage.
Now suppose the GC fires collection, who all would be collected ?
This is the situation: I am trying to build an uploader that will take data collected earlier in the form before the upload occurs and then rename the uploaded file with it. I've gotten the upload itself to work, but thus far I have no luck getting any sort of renaming to work, not even by PHP. I tried Loadvars to transfer the variables over and rename it during upload, yet it says "NO" and rejects the post variables when the upload occurs. I even tried loading the variables into an external file and transfering them back to the uploader via cookie, all at the same time. Again it says "NO!", and the file is uploaded as __"filename".jpg. This is my code thus far:

I have that function in the class:
private function fireItemCreated(data: ByteArray): void {
setTimeout(function(): void {
var event: ItemCreatedEvent = new ItemCreatedEvent(data);
dispatchEvent(event);
}, 1000);
}
This function called to dispatch item created event when image thumbnail created.But it delays event on some time to prevent user interface freezes. And I'm guessing what could be happen if garbage collector executes after fireItemCreated function call but before timer event. Does the closure will be removed or it stays until it will be executed?
I'm trying to set up a test that will tell me whether a variable exists in memory or not. I'm running into the problem of my nested function preserving the local variable it uses, called "shouldBeDead". Here's my best effort, which doesn't work for me because the "shouldBeDead" variable is still alive[code]...
View 4 RepliesI recently posted on here about tweening in alphas of thumbnails that I was adding to a movieclip. It seems that the tween is getting garbage collected because not all of the thumbs fade in all the way. I have the tween defined outside of the function, but it is tweening a loader that is created within the function. Could this cause the tween to get garbage collected? if so, how do I fix it?
Here is the pertinent code:
var thumbTween:Tween;
var my_thumb:Loader;
function thumbLoaded(e:Event):void{

I have had a few complications with syncing the notes coming down, then I realized tweens would be the best way to go, so I chose them.The problem is; the notes come down the screen. If there is any lag in performance, any note that is on the screen freezes on the spot, and the new notes come down, and stay in sync.This is telling me it's something to do with the tweens. The timeOuts I have set work fine for spawning notes at the right time, but the tweens are freezing on occasion, Im guessing because the timer for the tween keeps going, but flash does not notice it.Here is the code for adding the notes:
Code:
var myTween:Tween;
var timeWindow = 1;

I've got a custom component (quite complex so I can't post any code here, although that shouldn't matter), that I can add to a view. When the component is deleted from the view or the view is switched I call my own dispose method which removes remaining eventListeners and kills some references so that the component can eventually be nulled and collected by the GC.
All that works perfectly fine until I add a Spark TextInput to the MXML part of the component (it took me hours to find out what is preventing the component to be collected!), so I recon that the TextInput somehow automatically adds some eventListeners.
My question is what are these listeners, or is there anything else I haven't thought of?
can a loader get removed (garbage collected) whilst its still loading? does it have to be added to the stage or to an array?
