Interface IActiveResource

All Known Implementing Classes:

AbstractActiveResource, SimDelayResource, SimFCFSResource, SimProcessorSharingResource, SimProcessorSharingResourceLinuxO1, SimProcessorSharingResourceWindows

public interface IActiveResource

An active resource can execute demands of schedulable processes. Active resources are shared by multiple processes so that they need to use scheduling strategies to assign processing time of the resources to processes.

Method Summary

Modifier and Type	Method	Description

String	getId()	Unique identifier of the resource.
String	getName()	Name of the resource.
int	getQueueLengthFor(SchedulerEntity schedulerEntity, int coreID)	Get the number of processes currently having requests issued to this resource and waiting for the request to complete.
double	getRemainingDemand(ISchedulableProcess process)	Returns the remaining demand for a process.
void	notifyTerminated(ISchedulableProcess simProcess)
void	process(ISchedulableProcess process, int resourceServiceId, Map<String,Serializable> parameterMap, double demand)	Processes the specified demand of the process.
void	registerProcess(ISchedulableProcess runningProcess)
void	removeObserver(IActiveResourceStateSensor observer)
void	start()	Creates the initial events for the resource.
void	stop()
void	updateDemand(ISchedulableProcess process, double demand)	Update (currently consuming) demand for a process.
