AFAIK, any instances will remain in memory if there is a reference to it
anywhere. Even if you call the remove methods, they just remove them from
the Stage/screen but not from the memory stack. You will have to remove any
references in any instances in order to garbage collect them properly.

Subject: [Flashcoders] would this bother you?

hello flashcoders,

i have two fundamental questions. they somewhat keep bothering me:

1. what are the datatypes of a MovieClip instance and a Textfield
instance after calling removeMovieClip()/removeTextField() on that
MovieClip/Textfield instance?

2. do they remain in the memory after
removeMovieClip()/removeTextField()? do i need to delete the
references to them in order to have them garbage collected?

pls see below:

var tn:MovieClip = this.createEmptyMovieClip(tn, 0);
var tn_nested:MovieClip = tn.createEmptyMovieClip(tnNested, 0);
var tf_nested:TextField = tn.createTextField(tf, 1, 0, 100, 100, 100);
tf_nested.text = hello world!;
tn.loadMovie(http://assets0.twitter.com/images/twitter.png?1175908827;);

destroy_btn.onRelease = function(){
tf_nested.removeTextField();

tn.removeMovieClip();

trace(is tn instanceof MovieClip after removeMovieClip: +(tn
instanceof MovieClip));//false
trace(is tn instanceof Object after removeMovieClip: +(tn
instanceof Object));//false
trace(tn type after removeMovieClip: + typeof(tn));//movieclip
trace(is tf_nested instanceof Object after removeMovieClip:
+(tf_nested instanceof Object));//false
trace(tf_nested type after removeMovieClip:
+(typeof(tf_nested)));//movieclip
trace(tn is +tn+; tf_nested is +tf_nested);//tn is ; tf_nested
is

delete tf_nested;
delete tn;

trace(newline+delete tn);
trace(tn after destroy: +(tn instanceof MovieClip));
trace(tn after destroy: +(tn instanceof Object));
trace(tn type after destroy: + typeof(tn));
trace(tf_nested type after destroy: +(typeof(tf_nested)));
}

Thanks much Dan and David, That makes it clear!

If you want to free up memory you need to 'delete' all the references,
not just removeMovieClip.  I grabbed this from the livedocs:

Usage 4: The following example shows the behavior of delete on object
references:

-
var ref1:Object = new Object();
ref1.name = Jody;
// copy the reference variable into a new variable
// and delete ref1
ref2 = ref1;
delete ref1;
trace(ref1.name +ref1.name); //output: ref1.name undefined
trace(ref2.name +ref2.name); //output: ref2.name Jody

If ref1 had not been copied into ref2, the object would have been
deleted when ref1 was deleted because there would be no references to
it. If you delete ref2, there are no references to the object; it is
destroyed, and the memory it used becomes available.
--

If only have one reference to the object, like in your code, then the
delete should do just fine to free the memory.  If you have copied it a
few times, then you will need to keep track of those copies in order to
free the memory.
