Examples of ptolemy.actor.sched.StaticSchedulingDirector

ptolemy.actor.sched.StaticSchedulingDirector
A director that uses static scheduling to govern the execution of the CompositeActor it belongs to.
This class does not directly implement a scheduling algorithm, but defers to its contained scheduler. The contained scheduler creates an instance of the Schedule class which determines the number of times each actor should be fired and their firing order. This allows new scheduling algorithms to be easily created for existing domains.
This class is generally useful for statically scheduled domains where a schedule can be constructed once and used to repeatedly execute the model. The Scheduler class caches the schedule until the model changes so that the schedule does not have to be recomputed. @author Jie Liu, Steve Neuendorffer @version $Id: StaticSchedulingDirector.java,v 1.91 2006/06/20 23:05:36 hyzheng Exp $ @since Ptolemy II 0.2 @Pt.ProposedRating Green (neuendor) @Pt.AcceptedRating Yellow (neuendor) @see ptolemy.actor.Director @see Scheduler @see Schedule
