And here’s an example I’m using in production which runs more than one task in
parallel. As you can see, it’s very easy to use:
public function embedFonts(render:Function):void{
if(fontsEmbedded()){
render();
} else {
var tasks:Array = [];
var font:FontVO = getAppliedFont();
if(!font.embedded){
tasks.push(new LoadFontTask(font));
}
font = getBulletFont();
if(font && !font.embedded){
tasks.push(new LoadFontTask(font));
}
var task:CompoundAsyncTask = new CompoundAsyncTask(tasks);
task.done(function(task:AsyncTask):void{
if(task.completed){
// we're good
render();
} else {
// status is "failed" -- we're failing silently
}
});
task.run();
}
}
And the LoadFontTask class looks like this:
public class LoadFontTask extends AsyncTask
{
public function LoadFontTask(font:FontVO)
{
super();
this.font = font;
}
private var font:FontVO;
override public function run(data:Object = null):void{
var fp:FontProxy = getProxy(FontProxy.NAME) as FontProxy;
fp.loadNow(font,fontLoadDone);
}
private function fontLoadDone():void{
if(font.embedded){
complete();
} else {
fail();
}
}
}
