Classpublic class NumericDataProvider
InheritanceNumericDataProvider Inheritance OnDemandEventDispatcher Inheritance Object
Implements IList

Language Version: ActionScript 3.0
Product Version: Flex 4.6
Runtime Versions: Flash Player 11, AIR 3

This IList class generates items that are a sequential series of numbers. The numbers range between the minimum and maximum properties. The stepSize property defines the difference between an item and the next item.

This class is used primarily as a data provider for the SpinnerList control; for example:

 <s:SpinnerList>
   <s:dataProvider>
     <s:NumericDataProvider minimum="0" maximum="23" stepSize="1"/>
   </s:dataProvider>
 </s:SpinnerList> 
 

The advantage of this class is that the item values are calculated on demand, instead of stored.

Because the values are calculated instead of stored, the addItem(), addItemAt(), removeAll(), removeItemAt(), itemUpdated() and setItemAt() IList methods are not supported.

Property Detail

length

property
length:int  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 4.6
Runtime Versions: Flash Player 11, AIR 3

The number of items in this collection. 0 means no items while -1 means the length is unknown.



Implementation
    public function get length():int

maximum

property 
maximum:Number

Language Version: ActionScript 3.0
Product Version: Flex 4.6
Runtime Versions: Flash Player 11, AIR 3

The value of the last item. This value must be larger than the minimum value.

The default value is 100.



Implementation
    public function get maximum():Number
    public function set maximum(value:Number):void

minimum

property 
minimum:Number

Language Version: ActionScript 3.0
Product Version: Flex 4.6
Runtime Versions: Flash Player 11, AIR 3

The value of the first item. This value must be smaller than the minimum value.

The default value is 0.



Implementation
    public function get minimum():Number
    public function set minimum(value:Number):void

stepSize

property 
stepSize:Number

Language Version: ActionScript 3.0
Product Version: Flex 4.6
Runtime Versions: Flash Player 11, AIR 3

The stepSize property controls the values of items between the first and last items. For each item, the value is calculated as the sum of the minimum and the item's index multiplied by this property.

For example, if minimum is 10, maximum is 20, and this property is 3, then the item values of this data provider are 10, 13, 16, 19, and 20.

The default value is 1.



Implementation
    public function get stepSize():Number
    public function set stepSize(value:Number):void

Method Detail

addItem

()method
public function addItem(item:Object):void

Language Version: ActionScript 3.0
Product Version: Flex 4.6
Runtime Versions: Flash Player 11, AIR 3

This function is not supported.

Parameters

item:Object

addItemAt

()method 
public function addItemAt(item:Object, index:int):void

Language Version: ActionScript 3.0
Product Version: Flex 4.6
Runtime Versions: Flash Player 11, AIR 3

This function is not supported.

Parameters

item:Object
 
index:int

getItemAt

()method 
public function getItemAt(index:int, prefetch:int = 0):Object

Language Version: ActionScript 3.0
Product Version: Flex 4.6
Runtime Versions: Flash Player 11, AIR 3

Gets the item at the specified index.

Parameters

index:int — The index in the list from which to retrieve the item.
 
prefetch:int (default = 0) — An int indicating both the direction and number of items to fetch during the request if the item is not local.

Returns
Object — The item at that index, or null if there is none.

getItemIndex

()method 
public function getItemIndex(item:Object):int

Parameters

item:Object — The item to find.

Returns
int — The index of the item, or -1 if the item is not in the list.

itemUpdated

()method 
public function itemUpdated(item:Object, property:Object = null, oldValue:Object = null, newValue:Object = null):void
