public class CTSchedule
extends Schedule

A static schedule for CT models. This class overrides the base class and uses an ArrayList implementation for the first level of the schedule, so that accessing subschedules takes constant time. A CT schedule is an array of schedules. The array always has length X, consisting of the following entries in that order (in a type-safe enumeration),

 CONTINUOUS_ACTORS
 DISCRETE_ACTORS
 DYNAMIC_ACTORS
 EVENT_GENERATORS
 OUTPUT_ACTORS
 OUTPUT_STEP_SIZE_CONTROL_ACTORS
 STATE_TRANSITION_ACTORS
 STATEFUL_ACTORS
 STATE_STEP_SIZE_CONTROL_ACTORS
 WAVEFORM_GENERATORS
 

Each entry is a schedule. Actors in the schedule are ordered according to the order they should be executed.

A typical use of this schedule is to get one of the above schedules. For example, to schedule an execution of dynamic actor schedule, (assume we have a CTScheduler called scheduler) do:

 CTSchedule schedule = scheduler.getSchedule();
 Iterator dynamicActorIterator =
 schedule.get(CTSchedule.DYNAMIC_ACTOR_SCHEDULE).actorIterator();
