套件flash.system
類別public final class ApplicationDomain
繼承ApplicationDomain Inheritance Object

語言版本: ActionScript 3.0
執行階段版本: AIR 1.0, Flash Player 9, Flash Lite 4

ApplicationDomain 類別是分離之類別定義群組的容器。 應用程式網域的用途為分割位於相同安全性網域中的類別。 這些網域能允許相同的類別具有多項定義,並允許其子系重新使用父輩定義。

應用程式網域會在透過 Loader 類別載入外部 SWF 檔時使用。 位於載入之 SWF 檔中使用的所有 ActionScript 3.0 定義,都會儲存在應用程式網域中,該網域則由 LoaderContext 物件 (會傳遞作為 Loader 物件之 load()loadBytes() 方法的 context 參數) 的 applicationDomain 屬性所指定。 LoaderInfo 物件也含有唯讀的 applicationDomain 屬性。

SWF 檔中的所有程式碼,都是為了存在於應用程式網域中而定義。 目前的應用程式網域也就是您的主應用程式的執行位置。 系統網域包含所有的應用程式網域 (其中也包括目前的網域),這表示其中含有所有的 Flash Player 類別。

每個應用程式網域 (除了系統網域以外) 都具有相關聯的父網域。 您的主應用程式之應用程式網域的父網域,就是系統網域。 只有在其父輩尚未定義載入的類別時,這些類別才會獲得定義。 因此,您不能以較新的定義覆寫載入類別的定義。

有關應用程式網域的使用範例,請參閱「ActionScript 3.0 開發人員指南」

ApplicationDomain() 建構函數能讓您建立 ApplicationDomain 物件。

參數
parentDomain:ApplicationDomain (default = null) — 如果沒有傳入父網域,這個應用程式網域便會將系統網域當做父輩。
方法詳細資訊

getDefinition

()方法
public function getDefinition(name:String):Object

語言版本: ActionScript 3.0
執行階段版本: AIR 1.0, Flash Player 9, Flash Lite 4

會從指定的應用程式網域取得公用定義。 定義可以是類別、名稱空間或函數的定義。

參數

name:String — 定義的名稱。

傳回值
Object — 與定義相關聯的物件。

擲回值
ReferenceError — 具有指定之名稱的公用定義不存在。

getQualifiedDefinitionNames

()方法 
public function getQualifiedDefinitionNames():Vector.<String>

語言版本: ActionScript 3.0
執行階段版本: Flash Player 11.3, AIR 3.3

會從指定的應用程式網域取得公用定義的所有完整名稱。定義可以是類別、名稱空間或函數的定義。從這個方法傳回的名稱可傳遞至 getDefinition() 方法,以取得實際定義的物件。

傳回的 Vector 屬於 String 類型,而每個 String 的格式為:package.path::definitionName

如果 definitionName 在最上層套件中,則會忽略 package.path::

以下列類別定義為列:

     package my.Example
     {
       public class SampleClass extends Sprite
       { }
     }

這個方法會傳回「my.Example::SampleClass」。

傳回值
Vector.<String> — 屬於定義名稱之字串的未排序 Vector。如果沒有定義,則為空的 Vector。傳回 <String>。

擲回值
SecurityError — 這個定義屬於呼叫程式碼無法存取的網域。

hasDefinition

()方法 
public function hasDefinition(name:String):Boolean

語言版本: ActionScript 3.0
執行階段版本: AIR 1.0, Flash Player 9, Flash Lite 4

ApplicationDomainExample.as

下列範例將示範執行階段類別的載入作業,以及如何呼叫位於其它 SWF 中的類別之公用方法。

注意:

  • 由於 ClassLoader 類別會載入 SWF 檔,所以本機安全性必須處於檔案系統層級。
  • 若要執行此範例,則 ApplicationDomainExample.swf 檔案所在的資料夾中必須有名為 RuntimeClasses.swf 的 SWF 檔。

請先從下列程式碼中建立 RuntimeClasses.swf 檔案:

 package {
   import flash.display.Sprite;
   public class RuntimeClasses extends Sprite
   {
     public function RuntimeClasses()
     {}
      
     public function greet():String {
       return("Hello World");
     }
   }
 }
 

然後實作下列程式碼,

package {
    import flash.display.DisplayObject;
    import flash.display.Sprite;
    import flash.errors.IllegalOperationError;
    import flash.events.Event;
    import flash.text.TextField;

    public class ApplicationDomainExample extends Sprite {
        private var loader:ClassLoader;
        private var tf:TextField = new TextField();

        public function ApplicationDomainExample() {
            addChild(tf);

            loader = new ClassLoader();
            loader.addEventListener(ClassLoader.LOAD_ERROR,loadErrorHandler);
            loader.addEventListener(ClassLoader.CLASS_LOADED,classLoadedHandler);
            loader.load("RuntimeClasses.swf");
        }

        private function loadErrorHandler(e:Event):void {
            tf.text = "Load failed";
            throw new IllegalOperationError("Cannot load the specified file.");
        }

        private function classLoadedHandler(e:Event):void {
            var runtimeClassRef:Class = loader.getClass("RuntimeClasses");
            var greeter:Object = new runtimeClassRef();

            tf.text = greeter.greet();
        }
    }
}

import flash.display.Loader;
import flash.errors.IllegalOperationError;
import flash.events.Event;
import flash.events.EventDispatcher;
import flash.events.IOErrorEvent;
import flash.events.SecurityErrorEvent;
import flash.net.URLRequest;
import flash.system.ApplicationDomain;
import flash.system.LoaderContext;

class ClassLoader extends EventDispatcher {
    public static var CLASS_LOADED:String = "classLoaded";
    public static var LOAD_ERROR:String = "loadError";
    private var loader:Loader;
    private var swfLib:String;
    private var request:URLRequest;
    private var loadedClass:Class;

    public function ClassLoader() {

        loader = new Loader();
        loader.contentLoaderInfo.addEventListener(Event.COMPLETE,completeHandler);
        loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,ioErrorHandler);
        loader.contentLoaderInfo.addEventListener(SecurityErrorEvent.SECURITY_ERROR,securityErrorHandler);
    }

    public function load(lib:String):void {
        swfLib = lib;
        request = new URLRequest(swfLib);
        var context:LoaderContext = new LoaderContext();
        context.applicationDomain=ApplicationDomain.currentDomain;
        loader.load(request,context);
    }

    public function getClass(className:String):Class {
        try {
            return loader.contentLoaderInfo.applicationDomain.getDefinition(className)  as  Class;
        } catch (e:Error) {
            throw new IllegalOperationError(className + " definition not found in " + swfLib);
        }
        return null;
    }

    private function completeHandler(e:Event):void {
        dispatchEvent(new Event(ClassLoader.CLASS_LOADED));
    }

    private function ioErrorHandler(e:Event):void {
        dispatchEvent(new Event(ClassLoader.LOAD_ERROR));
    }

    private function securityErrorHandler(e:Event):void {
        dispatchEvent(new Event(ClassLoader.LOAD_ERROR));
    }
}
ApplicationDomainExample.2.as

如果有多個 SWF 檔都包含相同名稱的已編譯類別,但是提供不同的實作,您可以將外部載入的 SWF 檔的類別與在本範例之後 SWF 檔的類別相互隔開。 在先前版本中,引用的子 SWF 是使用ApplicationDomain.currentDomain。 在本例中,則是建立新的ApplicationDomain,因此由 SWF 第二次所載入 Greeter 類別的屬性和方法並不會取代第一次所載入 Greeter 類別的屬性和方法。 您可以在 ClassLoaderload 方法中,修改當中的 context.applicationDomain 屬性來進行這項測試作業。

注意:

  • 由於 ClassLoader 類別會載入 SWF 檔,所以本機安全性必須處於檔案系統層級。
  • 為了執行這個範例,"en" 和 "es" 資料夾中必須各自都有名為 Greeter.swf 的 SWF 檔。

請使用下列程式碼,在 "en" 目錄中建立 Greeter.as 檔:

 package {
    import flash.display.Sprite;
    public class Greeter extends Sprite
    {
        public function Greeter()
        {
        }
        
        public function greet():String {
            return("Good Morning");
        }
    }
 }
 

然後在 "es" 目錄中建立非常類似的 Greeter.as 檔案:

 package {
    import flash.display.Sprite;
    public class Greeter extends Sprite
    {
        public function Greeter()
        {
        }
        
        public function greet():String {
            return("Buenos Dias");
        }
    }
}
 

編譯這兩個 SWF 檔,然後實作下列程式碼:

package {
    import flash.display.DisplayObject;
    import flash.display.Sprite;
    import flash.errors.IllegalOperationError;
    import flash.events.Event;
    import flash.text.TextField;
    import flash.text.TextFieldAutoSize;

    public class ApplicationDomainExample2 extends Sprite {
        private var spanishGreeterLoader:ClassLoader;
        private var englishGreeterLoader:ClassLoader;
        private var tf:TextField = new TextField();
        private var greetersLoaded:uint = 0;

        public function ApplicationDomainExample2() {
            tf.autoSize = TextFieldAutoSize.LEFT;
            addChild(tf);

            spanishGreeterLoader = new ClassLoader();
            spanishGreeterLoader.addEventListener(ClassLoader.LOAD_ERROR,loadErrorHandler);
            spanishGreeterLoader.addEventListener(ClassLoader.CLASS_LOADED,classLoadedHandler);
            spanishGreeterLoader.load("es/Greeter.swf");
            
            englishGreeterLoader = new ClassLoader();
            englishGreeterLoader.addEventListener(ClassLoader.LOAD_ERROR,loadErrorHandler);
            englishGreeterLoader.addEventListener(ClassLoader.CLASS_LOADED,classLoadedHandler);
            englishGreeterLoader.load("en/Greeter.swf");
        }

        private function loadErrorHandler(e:Event):void {
            tf.text = "Load failed";
            throw new IllegalOperationError("Cannot load the specified file.");
        }

        private function classLoadedHandler(e:Event):void {
            greetersLoaded++;
            if(greetersLoaded == 2) {
                greet();    
            }
        }
        
        private function greet():void {
            var spanishGreeter:Class = spanishGreeterLoader.getClass("Greeter");
            var englishGreeter:Class = englishGreeterLoader.getClass("Greeter");
            var greeter1 = new spanishGreeter();
            var greeter2 = new englishGreeter();
            
            tf.text = greeter1.greet() + "\n" + greeter2.greet();
        }
    }
}
