VectorCollection

Package | org.apache.flex.collections
Class | public class VectorCollection
Inheritance | VectorCollection ListCollectionView flash.utils.Proxy
Implements | ICollectionView

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

Property Detail

source | property

`source:*`

The source of data in the VectorCollection. The VectorCollection object does not represent any changes that you make directly to the source Vector. Always use the ICollectionView or IList methods to modify the collection.

This property can be used as the source for data binding.

Implementation
`public function get source():*`
`public function set source(value:any):void`
Constructor Detail

VectorCollection | () | Constructor

`public function VectorCollection(source:* = null)`

Constructor.

Creates a new VectorCollection using the specified source vector. If no Vector is specified an empty vector of type<*> will be used.

Due to the way the compiler (not the runtime) checks Vectors, we need to leave the source as an <*> until a compiler change can be implemented.

Parameters

| `source:*` (default = `null`)``
