Delayed

AI-generated Key Takeaways

• The Delayed interface is used for objects that require delayed action after a specific time.

• Implementations must define a compareTo method for ordering, aligning with the getDelay method.

• getDelay returns the remaining delay time, with zero or negative values signifying delay completion.

• Delayed acts as a mix-in style interface, extending functionality for scheduling tasks with a delay.

public interface Delayed implements Comparable<Delayed>

Known Indirect Subclasses RunnableScheduledFuture<V>, ScheduledFuture<V> RunnableScheduledFuture<V> A ScheduledFuture that is Runnable.  ScheduledFuture<V> A delayed result-bearing action that can be cancelled.

A mix-in style interface for marking objects that should be acted upon after a given delay.

An implementation of this interface must define a compareTo method that provides an ordering consistent with its getDelay method.

Public Method Summary

abstract long

getDelay(TimeUnit unit) Returns the remaining delay associated with this object, in the given time unit.

Inherited Method Summary

From interface java.lang.Comparable

abstract int

compareTo(Delayed o) Compares this object with the specified object for order.

Public Methods

public abstract long getDelay (TimeUnit unit)

Returns the remaining delay associated with this object, in the given time unit.

Parameters

unit	the time unit

Returns

• the remaining delay; zero or negative values indicate that the delay has already elapsed
