How to copy an ArrayCollection by value

March 21st, 2008

I came across the requirement to copy an ArrayCollection by value instead of by reference. Here is the solutions I used:

1
2
3
4
5

private var myCollection:ArrayCollection = new ArrayCollection();
 
for (var k:Number = 0; k < myCurrentCollection.length; k++) {
	myCollection.addItem(mx.utils.ObjectUtil.copy(myCurrentCollection[k]));
}

    Just saw this, it works and is simpler.

    newAC = ObjectUtil.copy (oldAC) as ArrayCollection;

    Call to a possibly undefined method copy.
