類別public class StorageVolumeChangeEvent
繼承StorageVolumeChangeEvent Inheritance Event Inheritance Object

語言版本: ActionScript 3.0
執行階段版本: AIR 2

當儲存空間掛接或解除掛接時,StorageVolumeInfo.storageVolumeInfo 物件會傳送 StorageVolumeChangeEvent 事件物件。StorageVolumeChangeEvent 類型有兩種:storageVolumeMountstorageVolumeUnmount

在 Linux 上,StorageVolumeInfo 物件只會針對實體裝置傳送 storageVolumeMountstorageVolumeUnmount 事件。當使用者透過網路掛接或解除掛接磁碟時,不會傳送事件。

某些裝置 (例如一些數位相機及電話) 在掛接或解除掛接時,會出現在 StorageVolumeInfo.getStorageVolumes() 陣列,但它們不會傳送 StorageVolumeChangeEvent 物件。

複製 Event 子類別的實體。

傳回新的 Event 物件,此物件是原始 Event 物件實體的副本。 您通常不會呼叫 clone(),因為 EventDispatcher 類別會在您重新傳送事件時自動呼叫它 (也就是說,當您從正在處理 event 的處理常式呼叫dispatchEvent(event) 的時候)。

新的 Event 物件包含原始物件的所有屬性。

在建立自己的自訂 Event 類別時,您必須覆寫繼承的 Event.clone() 方法,才能讓其複製自訂類別的屬性。 如果您沒有對加入事件子類別的所有屬性進行設定,這些屬性將無法在偵聽程式處理重新傳送的事件時,提供正確的值。

在這個範例中,PingEventEvent 的子類別,因此會實作專屬的 clone() 版本。

     class PingEvent extends Event {
         var URL:String;
         
     public override function clone():Event {
              return new PingEvent(type, bubbles, cancelable, URL);
        }
     }
