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.

| Versión de producto: | Flex 3 |
| Versiones de motor de ejecución: | 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.
Esta propiedad se puede utilizar como origen para la vinculación de datos. Cuando se modifica esta propiedad, distribuye el evento collectionChange .

source:Array| Versión del lenguaje: | ActionScript 3.0 |
| Versión de producto: | Flex 3 |
| Versiones de motor de ejecución: | 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.

| 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. |

of the item(s) specified in the items property. |
oldLocation | the previous location in the collection
of the item specified in the items property. |
