All Implemented Interfaces:

Runnable

Deprecated. As of version 4.0, to be removed in 8.0 or later. It has been replaced with TaskManager

public class TaskScheduler

extends Thread

TaskScheduler can iterate over scheduled tasks until there are no more to schedule, or until a shutdown time. To use, create an array of tasks. Instantiate the TaskScheduler, then start() it (to run on a thread) or run() it (to run on the current thread). It is recommended you run it on its own thread if the schedules for your tasks can cause TaskScheduler to sleep.
