ActionScript 3.0 :: Differences In Garbage Collection Between Windows And OSX?
Jan 26, 2010I'm still struggling with memory-leak problems in the mega-project I talked about earlier (a children's fashion 'virtual showroom', where up to 600 videos and 3600 hires images can be viewed in one session).I'm monitoring memory use like this:
[AS]memory = Math.floor(System.totalMemory/(1024*1024)*100)/100;[/AS]
I cleaned up a lot of code, reusing objects whenever I can, and removing references (nulling) whenever I can, and I'm now at a point where memory usage is 'under control' on Windows machines, but not so on OSX machines.Results only vary slightly between various browsers on the Mac, and Firefox seems to perform the 'best'.The fact that there's such an obvious difference in memory leaking on Windows and on OSX, leads me to believe that my code is now okay, and that I'm hitting on differences in Garbage Collection-behaviour between the Windows Flash Player and the OSX Flash Player.Should I advice my client against the use of Macs (eventhough they just bought 60 MacBooks just to run this application on) because of this?

Sep 16, 2011I have an array, crewPositionsAC that contains a list of position abreviatations - EP, PR, DR, WR, and so on. These positions are read in through an XML file each time my flex application loads. Also being populated from an XML is a project. Within a project, there are positions (a student assigned to a type of position listed within crewPositionsAC). These positions are not necessarily in the correct hierarchy order dictated by crewPositionsAC. I have all the positions within an ArrayCollection (positionsAC) with the following structure:
positionsAC (arrayCollection)
[0] = Array
[0] = startOffset
[1] = numDays
[code].....
Then, the user can click a button to add another position. When the "Add Crew Member" button is pressed, the user is presented with a list of possible positions to add. Currently, I simply add another array to positionsAC. This results in the recently added crew member to placed on the bottom of the list. I need to take positionsAC and reorder it based on it's [2] item (role) based on the hierarchy defined in the crewPositionsAC. crewPositionsAC has the following structure:
crewPositionsAC:
[0] = EP
[1] = PR
[2] = DR
[3] = WR
* continue until all possible position types are listed

View 2 RepliesXml - Flex Tree Control With Array Collection?
Apr 9, 2012Im trying to populate a tree control with an external xml file brought in via arraycollection but i need to group the xml data to display in the tree Okay my external xml file is called parts.xml and it looks like this:
[Code]...
additionally what i intend is for the user to have huge tree of parts and they select a node at the partnumber level and drag an drop it on to a datagrid where all the other tags of the part gets displayed.
Ive tried and tried many things without any luck. even now im thinking maybe if i looped through the array-collection and created a new array just for the tree to get it to display the way i need it, then when the user dragged and drop a part onto the grid i would have code that would look for that part number in the original arraycollection and add it to a new array just for the datagrid... i still dont know how i would create that new array for the tree!! cause the xml data is grouped by partgroup and then grouped again by parttype before you get the individual part numbers

Flex :: Showing XML Nodes From Array Collection
Jul 14, 2010I've got an XML Doc loaded in. I've created an Horizontal List and referenced the arraycollection as the Data Provider. But what I need to do now is then pull the data out from that. I have 3 nodes / variables. They are id, title, thumbnail. But when I go to pull through the data as : {videos.title} Flex Builder gives me the Error - "Access of undefined property videos". Now I know full well it exists, as when I set the dataProvider to {videos} it pulls through the data without issue.
My code is as follows :
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
minWidth="800" minHeight="600"

How do I go about getting the XML Node : title and of course the thumbnail too?

ActionScript 3.0 :: Garbage Collection And Arrays - Set It To Null, That Space Should Be Deleted?
Sep 25, 2009I have a question about garbage collection in AS3. Let's say that I create a simple class, Item and link a movieclip in my library to this class. Now, in my main program, I create an array of Item's as follows:
Code:
var problemArray:Array = new Array();
function myTest()[code]....
Have the three references in the array that point to the three objects been deleted??? I made sure to set weak referencing on the event listeners that I attached, so I would think they would be marked for garbage collection. I am used to working in C++ so I usually delete all of the items myself and use a destructor in my classes, but since flash uses the garbage collection, I can't even seem to see what the reference count is to even know if my objects are marked for garbage collection. My thought is that an array is just a space in memory and if I set it to null, that space should be deleted, but I'm not sure if it is truly deleting these references or not.
