      rp1.simulator.SimTaskQueue

All Implemented Interfaces:

java.lang.Runnable

Direct Known Subclasses:

SimScheduler

public class SimTaskQueue
extends java.lang.Thread

Provides queue of objects of type SimTask; this class is extended by SimScheduler to provide the backbone of the RP1 simulation. When tasks are added to the queue, they are inserted in order of the values of the time and priority fields and insertion sequence. The waitForNextTask method provides a way of getting the next task for processing or waiting until a new task is added. The SimScheduler extends this method by adding a clock-based delay to create an execution schedule for tasks.
