de.uka.ipd.sdq.workflow.jobs.DynamicSequentialBlackboardInteractingJob<BlackboardType>

Type Parameters:

BlackboardType - The type of the blackboard needed by all jobs in the sequential workflow

All Implemented Interfaces:

IBlackboardInteractingJob<BlackboardType>, ICompositeJob, IJob, Iterable<IJob>, Collection<IJob>, List<IJob>

public class DynamicSequentialBlackboardInteractingJob<BlackboardType extends Blackboard<?>>
extends DynamicSequentialJob
implements IBlackboardInteractingJob<BlackboardType>

A sequential workflow which may contain jobs which need access to a common blackboard for information exchange. By default, the cleanup method of all jobs is called right after their execution before starting the next job. In addition, the job is removed from the job list to ensure, objects are freed for the garbage collection. This job implementation allows to extend the job queue dynamically during execution.
