import nme.Lib;


class ThreadingExample extends Sprite {
	
	
	public function new () {
		
		super ();
		
		var data = new ShareData ();
		
		var first = Thread.create (setValue);
		var second = Thread.create (retrieveValue);
		
		first.sendMessage (data);
		second.sendMessage (data);
		
	}
	
	
	private function setValue ():Void {
		
		var data = Thread.readMessage (true);
		data.value = 100;
		
	}
	
	
	private function retrieveValue ():Void {
		
		var data = Thread.readMessage (true);
		trace ("The value is " + data.value);
		
	}
	
	
}

	private function setValue (newValue:Int):Int {
		
		mutex.acquire ();
		value = newValue;
		mutex.release ();
		return newValue;
