Sharing code between swfs

Lets say I have two swfs A and B, and at runtime, swf A loads swf B, and I wish to share code between them, to minimize file size and download times.

If swf B has some code (say. com.blah.HelloWorld), I tell the compiler to have swf B's source in swf A's classpath, but only do a compile-time link and not actually compile com.blah.HelloWorld into swf A.

This works, and I have tried it, using a the -includes and -externs compiler options.

However, My problem is that I wish to do this the other way. i.e. swf A and B (and potentially swf C) all need com.blah.HelloWorld, but I want com.blah.HelloWorld to be compiled into just swf A, have it as an external reference in swf B ( and potentially C as well.)

I tried doing this using the externs and includes, but I get ReferenceErrors when I do this.

I want to do this without a having a separate rsl, so I can reduce the number of http requests. Is this possible?

Solution

  • You can split your flex application into modules.

    Or you can access individual classes from an SWF loaded at runtime using the getDefinition method of the ApplicationDomain class:

    var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoad);
loader.load(new URLRequest("c.swf"));
//..
private function onLoad(e:Event):void
{
  var domain:ApplicationDomain = LoaderInfo(e.target).applicationDomain;
  var Type:Class = domain.getDefinition("pack.MyComponent") as Class;
  var myBox:Sprite = new Type();
  addChild(myBox);
}
