IList
interface. Operations on an ArrayList instance modify the
data source; for example, if you use the removeItemAt()
method on an ArrayList, you remove the item from the underlying
Array.
This base class will not throw ItemPendingErrors but it
is possible that a subclass might.

length:int [읽기 전용] | 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
Get the number of items in the list. An ArrayList should always know its length so it shouldn't return -1, though a subclass may override that behavior.
이 속성은 데이터 바인딩에 대한 소스로 사용할 수 있습니다. 이 속성을 수정하면 collectionChange 이벤트를 전달합니다.
구현
public function get length():intsource | 속성 |
source:Array| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 3 |
| 런타임 버전: | Flash Player 9, AIR 1.1 |
The source array for this ArrayList.
Any changes done through the IList interface will be reflected in the
source array.
If no source array was supplied the ArrayList will create one internally.
Changes made directly to the underlying Array (e.g., calling
theList.source.pop() will not cause CollectionEvents
to be dispatched.

Dispatched when the IList has been updated in some way.
The CollectionEvent.COLLECTION_CHANGE constant defines the value of thetype property of the event object for an event that is
dispatched when a collection has changed.
The properties of the event object have the following values. Not all properties are meaningful for all kinds of events. See the detailed property descriptions for more information.
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
items | An Array of objects with
information about the items affected by the event.
The contents of this field depend on the event kind;
for details see the items property |
kind | The kind of event. The valid values are defined in the CollectionEventKind class as constants. |
location | Location within the target collection
of the item(s) specified in the items property. |
oldLocation | the previous location in the collection
of the item specified in the items property. |
