public class CountDownWatch
extends StopWatch

A count down acts more or less like a stop watch, but in the way that it is not counting up, but counting down. If the StopWatch.start() method is called without setting a setCountDown(long), it will start counting down from the value KEY_COUNTDOWN. If the KEY_AUTOSTART property is set, the count down will begin right after construction. The value retrieved is always the remaining time.

Constructor Detail

CountDownWatch

public CountDownWatch(Map<String,String> prop)

Constructs a new count-down watch. The count-down value is set to KEY_COUNTDOWN (DEFCOUNTDOWN if not given). If the KEY_AUTOSTART property is true, the countdown starts right after the construction phase.

Method Detail

rescanned

public double rescanned(String key,
                        String old,
                        String newval)

If the countdown value changed or the autostart changed, we update the count down value or start the watch.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class StopWatch

getValue

public Number getValue()

Returns the current count-down value. The current value of the stop watch is therefore subtracted from the count-down start value, countdown. Time is in ms.

Specified by:

getValue in interface Value

Overrides:

getValue in class StopWatch

setCountDown

public void setCountDown(long newcount)

Sets a new count-down value. May also be called during an active count-down.

getCountDown

public long getCountDown()

Returns the starting value of the count down. Time is in ms.
