org.palladiosimulator.solver.visitors.AggregatedContextSEFFVisitor

public class AggregatedContextSEFFVisitor
extends SeffVisitor

Visitor that builds up the context model including the aggregated usage context. Extends the SeffVisitor and adds the calculation of execution frequencies. Uses the AggregatedContextExternalCallActionHandler instead of the ExternalCallActionHandler.

Constructor Details

AggregatedContextSEFFVisitor

public AggregatedContextSEFFVisitor(ContextWrapper ctxWrp,
 double frequency,
 org.palladiosimulator.pcm.seff.ServiceEffectSpecification seff,
 org.palladiosimulator.pcm.usagemodel.UsageScenario currentScenario)

Method Details

caseResourceDemandingSEFF

public Object caseResourceDemandingSEFF(org.palladiosimulator.pcm.seff.ResourceDemandingSEFF seff)

Extends SeffVisitor.caseResourceDemandingSEFF(ResourceDemandingSEFF): stores the described SEFF in the ComputedAggregatedUsage. Then calls SeffVisitor.caseResourceDemandingSEFF(ResourceDemandingSEFF). Handles resource demanding seffs. Goes to the first action within the seff..

Overrides:

caseResourceDemandingSEFF in class SeffVisitor

Parameters:

seff - the resource demanding seff

Returns:

the resource demanding seff

caseExternalCallAction

public Object caseExternalCallAction(org.palladiosimulator.pcm.seff.ExternalCallAction call)

Overwrites the SeffVisitor.caseExternalCallAction(ExternalCallAction). Does the same, but uses an AggregatedContextExternalCallActionHandler to handle the call, which in turn will instantiate an AggregatedContextSEFFVisitor for the next SEFF.

Overrides:

caseExternalCallAction in class SeffVisitor

Parameters:

call - the external call action

Returns:

the external call action

caseInternalAction

public Object caseInternalAction(org.palladiosimulator.pcm.seff.InternalAction action)

Extends SeffVisitor.caseInternalAction(InternalAction). Adds the calculation of a mean resource demand weighted by frequency of execution. Adds this information to the AggregatedResourceDemand. Then calls SeffVisitor.caseInternalAction(InternalAction). Handles internal actions. Invokes the internalActionHandler, then goes to the next action.

Overrides:

caseInternalAction in class SeffVisitor

Parameters:

action - the internal action

Returns:

the internal action

caseResourceDemandingBehaviour

public Object caseResourceDemandingBehaviour(org.palladiosimulator.pcm.seff.ResourceDemandingBehaviour behaviour)

Gets the frequency to execute this ResourceDemandingBehaviour by checking the container. If it is a BranchTransition or AbstractLoopAction, update the frequency before calling SeffVisitor.caseExternalCallAction(ExternalCallAction). Then resets the frequency for the next action or trasition. Then calls SeffVisitor.caseResourceDemandingBehaviour(ResourceDemandingBehaviour). Handles resource demanding behaviours. Goes to the first action within the behaviour..

Overrides:

caseResourceDemandingBehaviour in class SeffVisitor

Parameters:

behaviour - the resource demanding behaviour

Returns:

the resource demanding behaviour

getCurrentFrequency

public double getCurrentFrequency()

Get the current frequency of this object. This is not equal to the frequency of this ServiceEffectSpecification, because the current frequency reflects the frequency of the currently handled AbstractAction.
