'is' can only be used to test *instances*

So...

 

function checkImp(className:Class):Boolean

{

    return new className() is
IMyInterface;

}

 

will work.

 

You could also use describeType(className)
and iterate over the <implementsInterface> child tags, but this would be
much more expensive.

Subject: [flexcoders] Beta 2:
Evaluating interfaces



 

Wondering if there is ability
to find out if a Class implements an interface? As in:

function checkImp(className:Class): Boolean {
   return (className is IMyInterface);
}

I'm using the PopUpManager internally, and want to
check that whatever gets passed in implements my interface, first. 

Thanks,
