How to get all definitions in an ApplicationDomain of a loaded SWF? - actionscript-3

Question

When you load a SWF into another, the loader SWF can get specific definitions from the loaded SWF using ApplicationDomain.getDefinition(name:String). For example:
package
{
// ... imports
public class SWFLoader extends Sprite
{
private var loadedAppDomain:ApplicationDomain;
public function SWFLoader()
{
var request:URLRequest = new URLRequest("test.swf");
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onTestLoadComplete);
loader.load(request);
}
private function onTestLoadComplete(event:Event):void
{
var loaderInfo:LoaderInfo = LoaderInfo(event.target);
loadedAppDomain = loaderInfo.applicationDomain;
// Here we can get ANY defined symbol (class, namespace or function according to Adobe Flash help)
var someSymbolClass:Class = Class(loadedAppDomain.getDefinition("SomeSymbol"));
var someSymbolSprite:Sprite = Sprite(new someSymbolClass());
addChild(sprite);
}
}
}
How can I get all of the definitions in a SWF, without specifying each explicitly?

Answer 1

As of Flash Player 11.3, you can use ApplicationDomain.getQualifiedDefinitionNames().
See the official documentation for the method and this blog post about the Flash Player release.

Answer 2

EDIT: This is the quickest solution to your problem : http://www.bytearray.org/?p=175
Hi, you could use this library : https://github.com/claus/as3swf/wiki/
Don't have the time to do deeper test, but here is what i found :
1 - I have created a .swf containing in the library 2 exported MC, $Test and $Test2
2 - Once the .swf loaded by a Loader, i run this code :
var swf : SWF = new SWF(loader.contentLoaderInfo.bytes);
trace(swf);
3 - In the output you'll notice theses lines :
[76:SymbolClass]
Symbols:
[0] TagID: 2, Name: $Test2
[1] TagID: 1, Name: $Test
I think that there is a way to obtain this info directly thru the library API

Answer 3

You have to put the loaded SWF in the current ApplicationDomain.
Use ApplicationDomain.currentDomain to do that, on the ContextLoader info.
loader.load(request, new ContextLoader(false, ApplicationDomain.currentDomain));
It should work.

Following from the answer I received from a previous question I asked here a few days ago (it's about SWC , but in your case, it doesn't really make a difference )
Working with SWCs - getDefinitionByName issue
If both SWFs share the same ApplicationDomain, you should be able to access the loaded SWF classes directly by doing this:
//provided that SomeSymbol extends Sprite...
var someSymbolSprite:Sprite =new SomeSymbol();
On the other hand, you won't be able to do this
var SomeSymbol:Class = getDefinitionByName("SomeSymbol");
unless you create a library of objects from the loaded SWF
var ssym:SomeSymbol;
Check the above link for more details.
