AS3中对象的内存使用情况和垃圾回收(Memory usage and garbage collection of Objects in AS3)

 我想知道关于Object类型，特别是当涉及Flash中的垃圾回收时。 
 
 我知道在这样的情况下物品将准备好进行垃圾回收： 
 
// create
var ar:Array = [];

var mc:MovieClip = new MovieClip();
mc.addEventLisntener(blah, blah);

ar.push(mc);
addChild(mc);

// kill & gc
ar.splice(0, 1);
mc.removeEventListener(blah, blah);
removeChild(mc);
 
 但是，如何/将在下面的情况下收集垃圾。 
 
 假设我在我的课程MartysMC中有一个函数，我通过以下方式解析Object ： 
 
package
{
    import flash.display.MovieClip;

    public class MartysMC extends MovieClip
    {
        /**
         * Updates this
         * @param obj An object containing key/value pairs to represent new property values
         */
        public function update(obj:Object):void
        {
            var i:String;
            for(i in obj)
            {
                this[i] = obj[i];
            }
        }
    }
}
 
 现在我利用这个功能： 
 
var mmc:MartysMC = new MartysMC();

var dataObject:Object =
{
    x: 10,
    y: 34,
    alpha: 0.6
};

mmc.update(dataObject);
 
 dataObject会发生什么？ 这会从这里收集垃圾吗？ 即使如此，这条线的目的是什么呢？ 
 
mmc.update({x:15,y:18,name:"marty"});

I want to know about the Object type specifically when it comes to garbage collection in Flash.
 
I know that items will be ready for garbage collection in situations like this:
 
// create
var ar:Array = [];

var mc:MovieClip = new MovieClip();
mc.addEventLisntener(blah, blah);

ar.push(mc);
addChild(mc);

// kill & gc
ar.splice(0, 1);
mc.removeEventListener(blah, blah);
removeChild(mc);
 
But how/will an Object get garbage collected in situations like below.
 
Say I have a function in my class MartysMC that I parse an Object through:
 
package
{
    import flash.display.MovieClip;

    public class MartysMC extends MovieClip
    {
        /**
         * Updates this
         * @param obj An object containing key/value pairs to represent new property values
         */
        public function update(obj:Object):void
        {
            var i:String;
            for(i in obj)
            {
                this[i] = obj[i];
            }
        }
    }
}
 
And now I make use of this function like so:
 
var mmc:MartysMC = new MartysMC();

var dataObject:Object =
{
    x: 10,
    y: 34,
    alpha: 0.6
};

mmc.update(dataObject);
 
What happens to dataObject? Will this get garbage collected from here? Even still, what about the object in this line:
 
mmc.update({x:15,y:18,name:"marty"});
