Pacchettomx.collections
Interfacciapublic interface IList extends IEventDispatcher
Implementatori ArrayList, AsyncListView, ListCollectionView, NumericDataProvider

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

A collection of items organized in an ordinal fashion. Provides access and manipulation methods based on index.

An IList may be a view onto data that has been retrieved from a remote location. When writing for a collection that may be remote, it is important to handle the case where data may not yet be available, which is indicated by the ItemPendingError.

The ICollectionView is an alternative to the IList.

Descrizione delle proprietà

length

proprietà
length:int  [sola lettura]

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

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

Descrizione dei metodi

addItem

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

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

Adds the specified item to the end of the list. Equivalent to addItemAt(item, length).

Parametri

item:Object — The item to add.

addItemAt

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

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

Adds the item at the specified index. The index of any item greater than the index of the added item is increased by one. If the the specified index is less than zero or greater than the length of the list, a RangeError is thrown.

Parametri

item:Object — The item to place at the index.
 
index:int — The index at which to place the item.


Genera
RangeError — if index is less than 0 or greater than the length of the list.

getItemAt

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

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

Gets the item at the specified index.

Parametri

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.

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

Genera
ItemPendingError — if the data for that index needs to be loaded from a remote location.
 
RangeError — if index < 0 or index >= length.

getItemIndex

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

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

Returns the index of the item if it is in the list such that getItemAt(index) == item.

Note: unlike IViewCursor.findxxx() methods, The getItemIndex() method cannot take a parameter with only a subset of the fields in the item being serched for; this method always searches for an item that exactly matches the input parameter.

Parametri

item:Object — The item to find.

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

itemUpdated

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

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

Notifies the view that an item has been updated. This is useful if the contents of the view do not implement IEventDispatcher and dispatches a PropertyChangeEvent. If a property is specified the view may be able to optimize its notification mechanism. Otherwise it may choose to simply refresh the whole view.

Parametri

item:Object — The item within the view that was updated.
 
property:Object (default = null) — The name of the property that was updated.
 
oldValue:Object (default = null) — The old value of that property. (If property was null, this can be the old value of the item.)
 
newValue:Object (default = null) — The new value of that property. (If property was null, there's no need to specify this as the item is assumed to be the new value.)

Elementi API correlati

removeAll

()metodo 
public function removeAll():void

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

Removes all items from the list.

If any item is not local and an asynchronous operation must be performed, an ItemPendingError will be thrown.

See the ItemPendingError documentation as well as the collections documentation for more information on using the ItemPendingError.

removeItemAt

()metodo 
public function removeItemAt(index:int):Object

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

Removes the item at the specified index and returns it. Any items that were after this index are now one index earlier.

Parametri

index:int — The index from which to remove the item.

Restituisce
Object — The item that was removed.

Genera
RangeError — is index is less than 0 or greater than length.

setItemAt

()metodo 
public function setItemAt(item:Object, index:int):Object

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

Places the item at the specified index. If an item was already at that index the new item will replace it and it will be returned.
