StorageVolumeInfo.storageVolumeInfo object dispatches a StorageVolumeChangeEvent event
object when a storage volume is mounted or unmounted. There are two types of StorageVolumeChangeEvent:
storageVolumeMount and storageVolumeUnmount.
On Linux, the StorageVolumeInfo object only dispatches storageVolumeMount and
storageVolumeUnmount events for physical devices. It does not dispatch events when
the user mounts or unmounts volumes over a network.
Some devices, such as some digital cameras and phones, appear in the
StorageVolumeInfo.getStorageVolumes() array, but they do not dispatch StorageVolumeChangeEvent
objects when mounted or unmounted.

public function StorageVolumeChangeEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, path:File = null, volume:StorageVolume = null)| Language Version: | ActionScript 3.0 |

Creates a StorageVolumeChangeEvent object to pass as an argument to event listeners.
Parameterstype:String — The type of the event, accessible in the type property.
The StorageVolumeChangeEvent class defines two event types, the storageVolumeMount event,
represented by the StorageVolumeChangeEvent.STORAGE_VOLUME_MOUNT constant, and the
storageVolumeUnmount event, represented by the StorageVolumeChangeEvent.STORAGE_VOLUME_UNMOUNT
constant,

clone | () | method |
override public function clone():Event| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 2 |
Duplicates an instance of an Event subclass.
Returns a new Event object that is a copy of the original instance of the Event object.
You do not normally call clone(); the EventDispatcher class calls it automatically
when you redispatch an event—that is, when you call dispatchEvent(event) from a handler
that is handling event.
The new Event object includes all the properties of the original.
When creating your own custom Event class, you must override the
inherited Event.clone() method in order for it to duplicate the
properties of your custom class. If you do not set all the properties that you add
in your event subclass, those properties will not have the correct values when listeners
handle the redispatched event.
In this example, PingEvent is a subclass of Event
and therefore implements its own version of clone().
class PingEvent extends Event {
var URL:String;
public override function clone():Event {
return new PingEvent(type, bubbles, cancelable, URL);
}
}
Event — A new Event object that is identical to the original.

toString | () | method |
override public function toString():String| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 2 |
Returns a string containing all the properties of the Event object. The string is in the following format:
[Event type=value bubbles=value cancelable=value]
String — A string containing all the properties of the Event object.

The StorageVolumeChangeEvent.VOLUME_MOUNT constant defines the value of the
type property of a StorageVolumeChangeEvent when a volume is mounted.
The event has the following properties:

cancelable | false; there is no default behavior to cancel. |
currentTarget | The StorageVolumeChangeEvent object. |
file | A File object representing the storage volume. |
name | The name of the storage volume. |
target | The StorageVolumeChangeEvent object. |
type | "storageVolumeMount" |
