mx.collections.ArrayCollection (Flex 3)

Pacote	mx.collections
Classe	public class ArrayCollection
Herança	ArrayCollection ListCollectionView Proxy Object
Implementa	IExternalizable

The ArrayCollection class is a wrapper class that exposes an Array as a collection that can be accessed and manipulated using the methods and properties of the ICollectionView or IList interfaces. Operations on a ArrayCollection instance modify the data source; for exemplo, if you use the removeItemAt() method on an ArrayCollection, you remove the item from the underlying Array.
