Flash AS3 class Object calling methods

Question

HI all, i have a class file named Main.as and another class calledr icon.as

package {

    import icon;
    public class main {
        public var _time:String;
        function main() {

            _time="01:10";
            iconObj=new icon(this);

        }
        function timerFunction() {
            _time=newTime;
        }
    }
}

package {

    public class icon {
        public var mytime:NUmber;
        function icon(mainObj:*) {

            trace("My time "+mainObj._time)

        }

    }
}

//sample outout

// My time 01:10

How do i get the current update from the main class without calling the MainObj repeatedly. Is this possible in Flash AS3, or any other alternate method for this idea.

Check out the Observer Pattern. You can have a clock which notifies its observers once the time changes.

Ther are already libraries simplifing this job for you like as3-signals. You can also use flash.events.EventDispatcher for the same task.

If you "need to get the time from main class" you will have to ask for it, like "mainObj.time".

Store a reference to the Main class object locally in Icon

package 
{
    public class Icon 
    {
        public var mytime:NUmber;
        //store an instance of Main obj here.
        public var mainObj:Main;
        public function Icon(mainObj:Main) 
        {
           this.mainObj = mainObj;
        }
        //call this method whenever you want time
        public function readTime():void
        {
           trace("My time " + mainObj._time);
        }
    }
}
