Hello List,
I have two classes Time and Clock, see below. To get good encapsulation,
in the Time class I added a function called clone(). This returns a copy
of the Time instance, instead of a reference to it.
Now I run the code, using an interval that calls the
Clock.getElepasedTime(). While watching the Memory I can see it build
up. Does this mean that with every clone of the Time object it still
holds a reference and therefore doesnt get deleted by the garbage
collector.
Hope somebody can enlighten me..

class Clock
{
private var startTime:Number;
private var elapsedTime:Time;
//constructor method
function Clock(tTime:Time)
{
clockdata = new ClockData()
startTime = getTimer();
}
public function getElepasedTime() : Time
{
var elapsedMilliseconds:Number = getTimer() - startTime;
var elapsedHours:Number = Math.floor(
elapsedMilliseconds / 3600000);
var elapsedSeconds:Number = Math.floor( elapsedMilliseconds
/ 1000);
var elapsedMinutes:Number = Math.floor( elapsedSeconds / 60);
elapsedSeconds = elapsedSeconds%60;
elapsedMinutes = elapsedMinutes%60;
if(elapsedTime == null){
elapsedTime = new Time(elapsedHours , elapsedMinutes ,
elapsedSeconds)
}else{
elapsedTime.hour = elapsedHours;
elapsedTime.minute = elapsedMinutes;
elapsedTime.second = elapsedSeconds;
}
return elapsedTime.clone();
}
}
class Time
{
private var _hour:Number;
private var _minute:Number;
private var _second:Number;
//constructor method
public function Time(hour:Number , minute:Number , second:Number)
{
_hour = hour
_minute = minute
_second = second
}
public function get hour() : Number
{
return _hour
}
public function set hour(nHour:Number) : Void
{

public function get minute() : Number

public function get second() : Number

var minutePrefix:String = ( (_minute < 10) ? '0' : '');
var secondPrefix:String = ( (_second < 10) ? '0' : '');
var hourPrefix :String = ( (_hour < 10) ? '0' : '');
return
String(hourPrefix+_hour+':'+minutePrefix+_minute+':'+secondPrefix+_second);
