How to getDefinitionByName of a packageless class in AS3?

Question

Say you have a flexunit test that looks like this:

package foo {
    import flexunit.framework.TestCase;
    import flash.utils.getDefinitionByName;
    import flash.utils.getQualifiedSuperclassName;
    class DescribeTypeTest {
      public function testDescribeInnerType():void {
        var currentInstance:ChildBar = new ChildBar();
        trace(getDefinitionByName(getQualifiedSuperclassName(currentInstance)));
      }
    }
}
class Bar{}
class ChildBar extends Bar{}

Which throws the exception "Error #1065: Variable Bar is not defined." It only applies to inner classes (classes outside the package).

Does anyone have any way to get this to work?

Not sure if there is any workaround, but just to confirm:

http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/utils/package.html#getDefinitionByName():

getDefinitionByName () function
public function getDefinitionByName(name:String):Object Language Version : ActionScript 3.0 Runtime Versions : AIR 1.0, Flash Player 9 Returns a reference to the class object of the class specified by the name parameter.

Parameters

name:String — The name of a class. Returns Object — Returns a reference to the class object of the class specified by the name parameter.

Throws ReferenceError — No public definition exists with the specified name.

Since both Bar and ChildBar are non-public, you're getting that ReferenceError.

I just tested following code with Flex 3.3 (AIR app):

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml"
    creationComplete="t();">
    <mx:Script>
        <![CDATA[
            import flash.utils.describeType;
            import flash.utils.getQualifiedSuperclassName;
            private function t():void {
                trace(getDefinitionByName(getQualifiedSuperclassName(new FooBar())));
            }
        ]]>
    </mx:Script>
</mx:WindowedApplication>

Bar.as

package
{
    public class Bar
    {
    }
}

FooBar.as

package
{
    public class FooBar extends Bar
    {
        public function FooBar()
        {
            super();
        }        
    }
}

As a trace result I see:

[SWF] DefTest.swf - 1,024,228 bytes after decompression
[class Bar]

Can you confirm this? Does that helps?

Can't be inside the package. The point is to load private (packageless) classes. — , Jun 17 '09 at 15:09
