Method Details

analyse

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

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:

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

AnalysisFailedException

org.eclipse.core.runtime.CoreException

retrieveResultsFor

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

FIXME: Make this method independent of the blackboard state.

Specified by:

retrieveResultsFor in interface IAnalysis

Parameters:

pheno - TODO

Returns:

Throws:

AnalysisFailedException

handleException

protected abstract IAnalysisResult handleException(RuntimeException e,
 org.palladiosimulator.solver.core.models.PCMInstance pcm)

try to handle the exception or throw it back.

Parameters:

e -

pcm -

Returns:

getSolverMessageString

protected abstract String getSolverMessageString()

retrieveResult

protected abstract ILQNResult retrieveResult(org.palladiosimulator.solver.core.models.PCMInstance pcm,
 org.palladiosimulator.solver.lqn.LqnModelType model,
 org.opt4j.core.Criterion criterion)
                                      throws AnalysisFailedException

Throws:

AnalysisFailedException

initialise

public void initialise(DSEWorkflowConfiguration configuration)
                throws org.eclipse.core.runtime.CoreException

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:

org.eclipse.core.runtime.CoreException

setBlackboard

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