Actionscript 3 :: Determine A Caller's Class?
Apr 21, 2011
since the MXMLC compiler doesn't support mixed access modifiers for setters/getters, i would like to know whether a public setter function is being called from inside or outside of the setter's class. this approach should allow me to maintain a public property but with more security, something like public/private hybrid access. is it possible to use arguments' callee property, or perhaps something else, to determine whether the setter was set internally from the setter's class or if it was set externally?

I have 3 swfs, and let's label them MovieA, MovieB, and MovieC. MovieB is a child of MovieA, and MovieC is a child of MovieB. So the hierarchy goes like this: MovieA -> MovieB -> MovieC. Each of these movies have their own document class, so they are each essentially a class extending MovieClip.
Now I have this other external class which contains only static variables. Let's call this class "TestClass" and let's say one of its static variables is called "testVar". So in MovieB's document class, I imported TestClass and set testVar = "hello world". In MovieC's document class, I imported TestClass and traced TestClass.testVar. When I publish and run MovieB, testVar is successfully traced as "hello world". Now when I publish and run MovieA, testVar is traced as undefined.

i'd like to throw an argument error if a particular function doesn't work without a passed value that also happens to be a public constant of the class containing the function.is there anyway to determine if a class owns a public constant instead of having to iterate thru all of them? something like this:
public static const HALIFAX:String = "halifax";
public static const MONTREAL:String = "montreal";
public static const TORONTO:String = "toronto";[code]....
currently, for this functionality i have to write the city setter function like this:
public function set city(value:String):void
{
if (value != HALIFAX && value != MONTREAL && value != TORONTO)[code].....

I am working on a Flex Front End at the moment, and have been using the Parsley framework for passing messages/events around.
I was wondering if there is a simple way for a function (in this case, an event's constructor) to obtain a reference to the object which called it?
This is to ensure that a certain event that I am defining can only be dispatched by one specified class. My thinking is to check the caller of the constructor somehow, and throw an error if it is not of the correct type.

For this example, I will use 2 classes, Entity and CSpawner. CSpawner is a children of Entity.I want to perform the following condition:if((new CSpawner()) is Entity)It works just like intended.But I want to do this test, without creating a new CSpawner object, something like this:if(CSpawner is Entity)But it doesn't work, because CSpawner is a Class.How do I perform that kind of conditional without creating a new CSpawner object?

In Actionscript 3, if I'm given a Class object, is there any way to determine if that class extends from another given class? I don't want to instantiate the class to check it with the is keyword, though.

I recently found a method (ByteArray.clear()) that FlexBuilder complains is possibly undefined; however, the method is in fact documented in the Flex LiveDocs. It must have been added in a later version of the SDK than I have installed. I'm not asking about this particular method, but I'm giving it as an example of the documentation issue that I'm trying to resolve. My questions are:
How can I determine what version of the SDK or Flash player that a method or property was added in? How can I tell which versions of the SDK are supported on which Flash player versions?
I want to be able to determine from the documentation, instead of compiler or runtime errors, what SDK and Flash player versions are needed to support newly added methods.
With Java I look for the @since javadoc tag when I need to know this, but I can't find an equivalent feature in the Flex docs.

If I've got a public function in a class that I know is being called from an object outside the class, is there any way to access either a reference to the calling object or at least the calling object's type from within that function without passing the caller through as a parameter?

I'm basically trying to refresh a jpg image every second from within my flash project. The code so far:
Code:
//This function is called from the loader's event listener.
//It moves the loaded image into the appropriate container for display
function imgLoaded(event:Event):void
[Code].....
And then it will load the picture, then it will throw the error, then load, then throw, etc...
What do I need to do to avoid this error?

This is the error I am getting....This is the situation I am using addChild and removeChild. I have two main movieclips that this is based around. workss_mc and work_mc. workss_mc is the slideshow, work_mc is the selection grid. When you click on an object in work_mc I am adding adding a child (workss_mc) and removing work_mc at the same time. That works fine; however, in workss_mc I have a back button, this back button is used to remove works_mc once it is removed it sends you back to work_mc. Once you are back on work_mc everything should work completely the same, however, it's like it's ignoring the code.Here is the code for the button:
Code:
urbanthmb_mc.addEventListener(MouseEvent.CLICK, clickHandler);
function clickHandler(event:Event) {
var workss_mc = new mc_workss();[code].......

This code throws an error:
if (modalMessage != null && contains(modalMessage)) {
removeChild(modalMessage); // the error is here
modalMessage = null;
}
The Error is:
[Fault] exception, information=ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
How can this be? I am checking if it is a child beforehand.

I encapsulate my addChild so that I can have an array of all the objects that are on stage for later garbage collection. this is how I do so [code]each gameObject has a property called garbage that is a boolean that is set when ready to be removed. When I set it to tree, this is what happens.ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

I have seached and tried for weeks on this, and I cannot get the grip on this. The simple code below gives the "The supplied DisplayObject must be a child of the caller" error.[code]squareObj is a movieclip in the library which is exported for AS. How can this code be altered to make it work correctly?

I have 2 classes representing 2 objects. From the "whoCalledMe" function, I want to find out what object called the function (without passing that information in as an argument). I've used a make-believe property, "caller", that would give me the reference I'm looking for. Is there a generic way I can get a reference to the caller from there?
package {
public class ObjectCallingTheFunction {
public var IDENTITY:String = "I'm the calling function!";

I having problems setting the child index of a sprite... It works perfectly on the first run of the program, but fails on the second time around. For context this function is in a class which accepts an array of sprites and displays them. My problem is with setChildIndex(_selected as DisplayObject, numChildren-1);
private function enlarge(e:MouseEvent):void{
if (!_open) {
_selected = e.currentTarget;
_selectedOrigX = _selected.x;
_selectedOrigY = _selected.y;
_selectedID = _selected.id;

I made a custom event that's supposed to be fired when a specific function within a class is executed. I listen for this event from within my main script, frame one of my timeline. My CustomEvents.as
package {
import flash.events.Event;
public class CustomEvents extends Event {
public static const PAGE_EMPTY:String = "Page Empty";
[code]...
I know I am reaching the CustomEvents constructor, as the trace within it gets printed.The problem is it seems like the event does not reach the function caller?I was unable to find good examples of how to use simple custom events, so this is how I think it's supposed to be.

With this code I generate 20 bubbles. Made of a Library item. Then I let them scroll accross the stage at various speeds. When each bubble moves off the stage at the right I want to delete it. So I used removeChild, but then I get this The supplied DisplayObject must be a child of the caller" error." What am I doing wrong?

I have to arrays, they both hit detect against each other. When they detect a hit they each launch a method in the custom class as well as splice the entries out of the arrays. Now, I CAN NOT remove the child right their cause that causes them to immediately delete themselves from the stage, I need the death animation to play. I can't remove them in the class cause it says it can only be removed from the caller.
Code:
for(var b=0; b<blastArray.length;b++){
for(var s=0; s<boxArray.length;s++){
if(blastArray[b].hitTestObject(boxArray[s])){ //test if they hit each other
[code]....
If I put removeChild(this) in the boxArray method .die, I get a 2025 error.
If I try parent.removeChild(this), I get, cannot access property of a null object. 1009 error.
