I know a solution may already be found but this was my first thought and I
am curious how any of you feel about switch (true) for this problem
switch (true) {
case loadedDisplayObject is MovieClip:
case loadedDisplayObject is Bitmap:
}
Is switch (true) just bad practice? and does 'is' not

Very nice!!! Many thanks Karim
I will test it out and let you know how it goes. :)
Have an excellent day/night!

Hello,
I am using this class:
http://code.google.com/p/as3-multiple-file-preloader/
And I need to determine the display object type (i.e. is it MovieClip
or Bitmap).
trace(getQualifiedClassName(loadedDisplayObject));
Gives me this output (in a loop of 3 images and 1 swf loaded):

trace(getQualifiedClassName(loadedDisplayObject));
Would that be the best way to test for MovieClip or Bitmap?
It fails the empty base class test. It is an extremely bad way.

How about up-casting:
var mc:MovieClip = loadedDisplayObject as MovieClip;
if(mc) {
mc.play();
} else {
//could be a bitmap, but if it's not guaranteed, then you might
need to do more tests.
var bmp:Bitmap = loadedDisplayObject as Bitmap;
}

Sorry, I meant downcast

Ah, I am glad I asked! :D
Any tips on a better way to test display object if it is

Hi,
If your downcast does not work - the as bit - your variable will
be null -it does not throw exceptions.

Excellent! Thanks for
attached a class that does that, hope it helps...
example :
trace( ClassUtils.getFullClassPath( canvas ) ); // flash.display.Bitmap
trace( ClassUtils.getSuperClass( canvas ) ); // flash.display.DisplayObject
