Class PlanRecord

java.lang.Object
  zeus.actors.PlanRecord

All Implemented Interfaces:

SuppliedRequester

public class PlanRecord

extends java.lang.Object

implements SuppliedRequester

PlanRecord is used to manage the execution of a (primitive, mutable or infered) task. The field task is the primitive task being executed, the field thread is the ZeusTask that is actually being run
