Interface Scheduler

All Superinterfaces:

Executor

All Known Implementing Classes:

ConcurrentScheduler

public interface Scheduler
extends Executor

The Scheduler interface represents a means to execute a task immediately or after a specified delay. This queues the task for the requested period of time before it is executed, if a delay is specified. How the task is executed is dependent on the implementation, however it will normally use a thread pool.

Method Detail

execute

void execute(Runnable task,
             long delay)

This will execute the task within the executor after the time specified has expired. If the time specified is zero then it will be executed immediately. Once the scheduler has been stopped then this method will no longer accept runnable tasks.

Parameters:

task - this is the task to schedule for execution

delay - the time in milliseconds to wait for execution

execute

void execute(Runnable task,
             long delay,
             TimeUnit unit)

This will execute the task within the executor after the time specified has expired. If the time specified is zero then it will be executed immediately. Once the scheduler has been stopped then this method will no longer accept runnable tasks.

Parameters:

task - this is the task to schedule for execution

delay - this is the delay to wait before execution

unit - this is the duration time unit to wait for
