public class SimulatedLinkingResource
extends AbstractScheduledResource

Realizes a LinkingResource. Adds the latency time to the passed demand in #consumeResource(SimuComSimProcess, double), and they is loaded by latency + demand / throughput.

Constructor Detail

SimulatedLinkingResource

public SimulatedLinkingResource(org.palladiosimulator.pcm.resourceenvironment.LinkingResource linkingResource,
                                SimuComModel simuComModel,
                                String resourceContainerID)

Method Detail

getId

public String getId()

createActiveResource

protected de.uka.ipd.sdq.scheduler.IActiveResource createActiveResource(SimuComModel simuComModel)

Description copied from class: AbstractScheduledResource

Subclasses are responsible for creating the IActiveResource to use internally. Is called in the constructor.

Specified by:

createActiveResource in class AbstractScheduledResource

Returns:

the IActiveResource resource to use as determined by the subclasses.

calculateDemand

protected double calculateDemand(double demand)

Description copied from class: AbstractScheduledResource

Template method. Implementers have to use the given demand and return the time span needed to process the demand on this resource.

Specified by:

calculateDemand in class AbstractScheduledResource

Parameters:

demand - The demand issued to this resource in units understood by the resource

Returns:

The service time, given in seconds

consumeResource

public void consumeResource(SimuComSimProcess process,
                            int resourceServiceID,
                            Map<String,Serializable> parameterMap,
                            double abstractDemand)

Description copied from class: AbstractScheduledResource

Called by client of this resource to make the resource simulate resource processing. This is the queueing network service center part of our simulation. Allows passing of additional parameters.

Specified by:

consumeResource in class AbstractScheduledResource

Parameters:

abstractDemand - : may be zero, in that case only the latency is considered.

process - The thread or job requesting the processing of its demand

resourceServiceID - The id of the resource service to be called for resource consumption

parameterMap - Additional parameters which can be used by the resource. Map can be empty.

getRemainingDemandForProcess

public double getRemainingDemandForProcess(SimuComSimProcess thread)

Specified by:

getRemainingDemandForProcess in class AbstractScheduledResource

updateDemand

public void updateDemand(SimuComSimProcess thread,
                         double demand)

Specified by:

updateDemand in class AbstractScheduledResource

getScheduledResource

public de.uka.ipd.sdq.scheduler.IActiveResource getScheduledResource()

Specified by:

getScheduledResource in class AbstractScheduledResource

activateResource

public void activateResource()

Description copied from class: AbstractScheduledResource

Called by the framework to inform that the resource should start its lifecycle

Overrides:

activateResource in class AbstractScheduledResource

deactivateResource

public void deactivateResource()

Description copied from class: AbstractScheduledResource

Called by the framework to inform the resource that the simulation has been stopped. Fires a IStateListener#stateChanged() event.

Overrides:

deactivateResource in class AbstractScheduledResource

getNextResourceId

public static String getNextResourceId()

getLinkingResource

public org.palladiosimulator.pcm.resourceenvironment.LinkingResource getLinkingResource()

setThroughput

public void setThroughput(String throughput)

Change the linking resource throughput after its creation.

Parameters:

throughput - the new throughput specification

setLatency

public void setLatency(String latency)

Change the linking resource latency after its creation.

Parameters:

latency - the new latency specification
