    Class method to return filtered arrayCollection

      I am trying to combine a number of related properties and methods into one class. One of those methods is to return all tracks of a cd. A call to the method would look something like this:

      var track:Track = new Track();
      var cdTracks:ArrayCollection = new ArrayCollection();
      cdTracks = track.getCDTracks(cdID);

      The Track Class might look something like:
      private var _theTracks:ArrayCollection;

      public function getCDTracks(cdID:Object):ArrayCollection {
      return _theTracks;

      private function getTracks(cdID:Object):void {
      ... remote object returns tracks that belong to cdID
      ro.addEventListener(ResultEvent.result, tracks_result);

      private function tracks_result(event:ResultEvent):void {
      _theTracks = new ArrayCollection(event.result as Array);
      ------------------------------------------------------------------------------------------ ----

      Obviously this won't work but you get the idea. One other thing i have thought of is to make a call to the db for ALL tracks of ALL cds upon instantiaion, then filter them when the getCDTracks method is run. Although i am a little worried this will really slow down the application when it first runs as this will eventually lead to TONS of data pre-loading when only a minimal amount is required.
