Hi Vivian,

Please email me so we can figure out a time that might work. jaward at adobe dot com

James, I am from SF bayarea and its been a while since you came and delivered any presentation here in San Francisco or San Jose! How can we schedule couple of events with you here in the bay area. By the way our user group name in Silvafug and we meet in Adobe offices in SF and SJ, twice every month. You have been to our meetings before but that was long time back.

Hi Matt,

Thanks for clarifying. Classes don’t get linked in unless they are explicitly referenced. In the full source you can see how I force that:

    if (0)
    {
      var someClasses:SomeClasses = new SomeClasses();
    }

You might want to note that when using SWCs, this will not work unless it is fully included. Otherwise, the class has to be referenced prior to the “search” as flash uses an on demand system for library classes. Otherwise, hats off to you! Great little tool!

The new more cleaner code based on Roland’s suggestions is:

    var a:Array = getDefinitionNames(systemManager.loaderInfo);
 
    allClasses.dataProvider = a;
 
    ifooClasses.dataProvider = new ArrayCollection();
    metafooClasses.dataProvider = new ArrayCollection();
 
    for each (var cn:String in a)
    {
      var t:Type = Type.forName(cn);
 
      if (t.hasMetaData("MetaFoo"))
      {
        metafooClasses.dataProvider.addItem(cn);
      }
 
      if (ClassUtils.isImplementationOf(t.clazz, IFoo);
      {
        ifooClasses.dataProvider.addItem(cn);
      }
    }

Much nicer! Thanks again Roland.

I was actually trying to figure out a solution for this last night. Thanks for the timely post, James.

Awesome! Thanks Roland! That simplifies the code quite a bit.

Hehe, ow, and while I’m at it, the Type class has a hasMetaData() method:

t.hasMetaData(“MetaFoo”);

Nice post James!
One thing though, I think this would be a neater way of doing the interface check:

ClassUtils.isImplementationOf(t.clazz, IFoo);

cheers,

Roland
