Class Countdown<T, SELF extends Countdown<T,SELF>>

java.lang.Object
dev.bouncingelf10.timelesslib.api.countdown.Countdown<T,SELF>
Type Parameters:
T - Context type (e.g. the server or client instance) passed to handlers.
SELF - Concrete subtype, so builder-style methods return the right type. See ServerCountdown / ClientCountdown.
All Implemented Interfaces:
TaskHandle
Direct Known Subclasses:
ClientCountdown, ServerCountdown
public abstract class Countdown<T, SELF extends Countdown<T,SELF>> extends Object implements TaskHandle
A single countdown-to-zero task, produced by ServerCountdownManager.start(Duration) / ClientCountdownManager.start(Duration).
Implements the same TaskHandle lifecycle (cancel(), pause(), resume()) as a plain scheduled task, plus richer countdown-shaped notifications (tick, finish, threshold, custom-interval handlers).
