Class FlowPlanElement

java.lang.Object
  gr.uoa.di.madgik.execution.plan.element.PlanElementBase
      gr.uoa.di.madgik.execution.plan.element.FlowPlanElement

All Implemented Interfaces:

IPlanElement, Iterable<IPlanElement>, Observer

public class FlowPlanElement
extends PlanElementBase
implements Iterable<IPlanElement>

This plan element acts as a container of other IPlanElements. It orchestrates their execution by executing the elements that are contained in the ElementCollection in parallel and waiting for their completion. If one of the elements is terminated with an error, after all the elements have terminated, the exception indicating the error is re-thrown. If more than one elements finished with an error, only the first error found iterating through the ElementCollection is thrown.
