Questions tagged [arraycollection]

The ArrayCollection class is a wrapper class that exposes an Array as a collection in Flex which can be accessed and manipulated. Use this tag for questions related to arraycollection.

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 example, if you use the removeItemAt() method on an ArrayCollection, you remove the item from the underlying Array.
