void	analyse(PCMPhenotype pheno, IProgressMonitor monitor)	Analyses the current PCM instance from the blackboard.

Method Detail

analyse

public void analyse(PCMPhenotype pheno,
                    IProgressMonitor monitor)
             throws CoreException,
                    de.uka.ipd.sdq.workflow.jobs.UserCanceledException,
                    de.uka.ipd.sdq.workflow.jobs.JobFailedException,
                    AnalysisFailedException

Description copied from interface: IAnalysis

Analyses the current PCM instance from the blackboard. This method can only be called after calling #initialise(MDSDBlackboard, ILaunchConfiguration, ILaunch). The PCM instance for this PCMPhenotype has to be copied to the Blackboard into partition LoadPCMModelsIntoBlackboardJob.PCM_MODELS_PARTITION_ID before callings this. Otherwise, a wrong PCM model is analysed. The Analysis has to store the results for this PCMPhenotype, so that IAnalysis.retrieveResultsFor(PCMPhenotype, Criterion) can be called on it multiple times. The results should be stored in a memory-efficient way.

Specified by:

analyse in interface IAnalysis

Parameters:

pheno - TODO

Throws:

CoreException

de.uka.ipd.sdq.workflow.jobs.UserCanceledException

de.uka.ipd.sdq.workflow.jobs.JobFailedException

AnalysisFailedException

initialise

public void initialise(DSEWorkflowConfiguration configuration)
                throws CoreException

Description copied from interface: IAnalysis

Saves the passed Run Configuration information so that we do not have to pass them as parameters all the time. For real analyses, you need to call setBlackboard before this so that the objectives can be determined from the usage model. For the AnalysisProxy it is ok to call this first, you then need to call setBlackboard before calling IAnalysis.analyse(PCMPhenotype, IProgressMonitor), #retrieveLastResultsForObjective(Objective), #getObjectives(), or IAnalysis.hasObjectivePerUsageScenario().

Specified by:

initialise in interface IAnalysis

Throws:

CoreException

getCriterions

public List<org.opt4j.core.Criterion> getCriterions()
                                             throws CoreException

Description copied from interface: IAnalysis

Can only be called after initialisation (#initialise(MDSDBlackboard, ILaunchConfiguration, ILaunch, IProgressMonitor)).

Specified by:

getCriterions in interface IAnalysis

Overrides:

getCriterions in class AbstractAnalysis

Returns:

Throws:

CoreException

retrieveResultsFor

public IAnalysisResult retrieveResultsFor(PCMPhenotype pheno,
                                          org.opt4j.core.Criterion criterion)
                                   throws CoreException,
                                          AnalysisFailedException

Description copied from interface: IAnalysis

This method can only be called after calling a #analyse() for this phenotype and the current PCM models of this candidate have to be in the Blackboard partition LoadPCMModelsIntoBlackboardJob.PCM_MODELS_PARTITION_ID FIXME: Make this method independent of the blackboard state. Currently, the SimuComAnalysis and the LQN analyses still require the current PCM model to be on the blackboard.

Specified by:

retrieveResultsFor in interface IAnalysis

Parameters:

pheno - TODO

Returns:

Throws:

CoreException

AnalysisFailedException

hasObjectivePerUsageScenario

public boolean hasObjectivePerUsageScenario()
                                     throws CoreException

Description copied from interface: IAnalysis

Returns whether this analysis provides one objective per usage scenario. This method can be called before calling #initialise(MDSDBlackboard, ILaunchConfiguration, ILaunch, IProgressMonitor).

Specified by:

hasObjectivePerUsageScenario in interface IAnalysis

Throws:

CoreException

setBlackboard

public void setBlackboard(de.uka.ipd.sdq.workflow.mdsd.blackboard.MDSDBlackboard blackboard)

Specified by:
