All Implemented Interfaces:

java.lang.Runnable

public class SimScheduler
extends SimTaskQueue

A time-driven task queue that provides the backbone of the RP1 simulator; this class extends SimTaskQueue by adding clock-driven delays between sunsequent tasks so that they are executed according to a time sequence. It does this by overloading the waitForNextTask from SimTaskQueue. In SimTaskQueue, waitForNextTask returns a task as soon as one is available. In SimScheduler, it waits until the next task in the queue is scheduled for processing. Note that sometimes tasks with a startTime value of zero meaning "for immediate execution." Such tasks will cause the waitForNextTask method to return control to the calling application without delay.
