flex에서 httpservice를 actionscript에 적용해서 하는 예제

포토뷰어라는 예제에 있는 것을 추출해 왔습니다
항상 모듈화라는 숙제를 가지고 보니 이런 좋은 예제가 아닌가 합니다.

package samples.photoviewer
{
 import flash.events.*;

 import mx.collections.ArrayCollection;
 import mx.collections.IViewCursor;
 import mx.core.Application;
 import mx.rpc.events.ResultEvent;
 import mx.rpc.http.HTTPService;
 import mx.utils.ArrayUtil;

 public class PhotoService
 {
  private var service:HTTPService;

        [Bindable]
  public var galleries:ArrayCollection;

  public function PhotoService(url:String)
  {
   service = new HTTPService();
   service.url = url;
   service.addEventListener(ResultEvent.RESULT, resultHandler);
   service.send();
  } // httpservice를 이용한 호출

  private function resultHandler(event:ResultEvent):void
  {
      var result:ArrayCollection = event.result.galleries.gallery is ArrayCollection
          ? event.result.galleries.gallery as ArrayCollection
          : new ArrayCollection(ArrayUtil.toArray(event.result.galleries.gallery));
      var temp:ArrayCollection = new ArrayCollection();
      var cursor:IViewCursor = result.createCursor();
      while (!cursor.afterLast)
      {
          temp.addItem(new Gallery(cursor.current));
          cursor.moveNext();
      }
      galleries = temp;
  }
 }
} // 결과를 arraycollection으로 적용

이 actionscript를 적용해서 구현을 한 예제를 보면

Viewstack을 가지고 처리를 해주는 것이다.
아울러 여기서 보여주는 콤포넌트에 대해서는 다음시간에 따로 설명을 하도록 하겠습니다.
조금씩 업무별로 가는 프레임웍에 대한 레퍼런스가 만들어지면 올리도록 하겠슴당 ㅋ
