View 2 RepliesFlex :: How To Get Memory Size Of ArrayCollection
Feb 2, 2010I have built an image cache which is an ArrayCollection containing images. I have built functionality so that the cache can hold a max of 250 images. However, the images can be of a different size, so it's better to limit the total memory size of all images in the ArrayCollection. How I can get the total memory size of an ArrayCollection without looping through all the items in the ArrayCollection?

Flex :: Mxml - Components Bound To Empty ArrayCollection At Load Time Don't Render As Expected When The ArrayCollection Is Updated?
Oct 27, 2009I'm new to Flex and am using TileList bound to an ArrayCollection. The array collection is empty at load time, and then updates with the results from am HTTPService call. The problem is that the item renderers aren't being rendered as expected, I'm guessing because there was no data when they were first rendered at load time. Here's simplified example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" >

Actionscript 3 :: Difference Between Primitive / Non-Primitive Objects For Memory Management?
Jul 4, 2011my understanding is that primitive types (uint, string, Number, etc.) of a class do not need to be set to null for garbage collection.
for example, i am not required to write this dispose() method in the following class:
package
{
//Imports
import flash.display.Shape;
[Code]....
if this is true, which i believe it is, what is the difference between objects of primitive types and objects of non primitive types concerning memory allocation?

Php :: Zend_AMF: Get A ArrayCollection From Flex?
Sep 22, 2009I currently have an arrayCollection in Flex and I want to sent it to PHP (Zend_AMF). According to the Zend_AMF wiki, sending an arrayCollection over directly will force Zend_AMF to cast the arrayCollection as an object which is no good. I'd rather have an array of my models. I assume the best way would be to convert the arrayCollection to an array in flex and then send it over. Is this true, and if so how would I do that in Flex 3? If you have a better recommendation,

Flex :: AdvancedDataGridRendererProvider ChildrenField ArrayCollection?
Feb 5, 2010I have a main class ClassA that has a bunch of "normal" properties that are simple datatype like ints, strings, etc. It also has one property ("childItems") that is an ArrayCollection of ClassB.I am using an ArrayCollection of ClassA as the source for an hierarchical data provider for an AdvancedDataGrid. I set the childrenField to "childItems".
I want to display some information about the list of ClassB objects in a nested table and pie chart, an AdvancedDataGridItemRendererProvider (columnIndex = 0, columnSpan = 0, depth = 2) and point it to my custom renderer which is an HBox with the table and the pie chart in it.
In order to see what is being set, I override the "set data" function in my custom renderer and what I see is that each instance of ClassB in the ArrayCollection is passed to the renderer separately.
Here is my question: I expected the whole ArrayCollection of ClassB instances to be passed to the custom renderprovider once and not each item in the child list individually. How do I make the ADG understand that the whole property is supposed to be passed as the data to the renderer and not each entry separately? Btw, when I change the data type of "childItems" from ArrayCollection to ArrayList, the whole list gets passed and I can easily do what I want to do. But based on my understanding, ArrayList is not really supposed to be used and ArrayCollection is better or at least more common.
Flex :: Getting Unique Elements From An ArrayCollection?
Mar 19, 2010I have an ArrayCollection as mentioned below.
private var initDG:ArrayCollection = new ArrayCollection([
{fact: "Order #2314", appName: "AA"},
{fact: "Order #2315", appName: "BB"}[code].....
I want to populate a ComboBox with UNIQUE VALUES of "appName" field from the ArrayCollection initDG.
<mx:ComboBox id="appCombo" dataProvider="{initDG}" labelField="appName"/>
One method I could think is to loop through the Array objects and for each object check and push unique appName entries into another Array. Is there any better solution available?
