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

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?

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.

Beautiful. At last Adobe added this functionality :) – Lucas Gabriel Sánchez Oct 24 '12 at 13:48
As of 3/31/2014, the method is not actually documented. There is no mention of `getQualifiedDefinitionNames` at the documentation link for ApplicationDomain. The method does, however, work, and it returns a `Vector.` of the classes defined in that particular ApplicationDomain. Also note that it doesn't return definitions of parent domains, even though getDefinition/hasDefinition will return true for classes defined in parent domains. – Triynko Mar 31 '14 at 19:06

It is documented there but you need to set the player version to 11.3 or above to see it. Up the top under the page title. – Glen Blanchard May 15 '14 at 05:12
@GlenBlanchard +1 for introducing me to the filters! Thanks! – Tom Auger Jul 14 '14 at 20:15

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

Excellent, I will use SWFExplorer Thanks! – Lucas Gabriel Sánchez Nov 10 '10 at 15:41 — Lucas Gabriel Sánchez, Nov 10 '10 at 15:41

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.

And then what? I have access to all classes, namespaces and functions of the loaded SWF? can I run: `var someSymbolSprite:Sprite = Sprite(new SomeSymbol())`? – Lucas Gabriel Sánchez Nov 10 '10 at 12:35
Yes, you can access every symbol in the loaded swf, just as if they was declared in the current movie. – blue112 Nov 10 '10 at 13:27

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.

But that's the same of the example, I have to know that the symbol `SomeSymbol` exists. I want a list of all symbols without hardcoding everyone. — Lucas Gabriel Sánchez, Nov 10 '10 at 15:38
