Class QueueScheduler

java.lang.Object
  |
  +--edu.iu.iv.common.QueueScheduler

All Implemented Interfaces:

Scheduler

public class QueueScheduler

extends java.lang.Object

implements Scheduler

A basic queue-based scheduler. When algorithms are in the queue, they are run one at a time by a separate thread, which is killed once the queue is emptied. runNow() and schedule() place algorithms at the front and back of the queue, respectively. This means that runNow() will not necessarily start an algorithm immediately - if another algorithm is already running, the scheduler thread will wait until that one is finished before running the new one.
