        public TransitionDeterminer​(InterpreterDefaultContext context)

    • Method Detail

      • createSummedProbabilityList

        protected List<Double> createSummedProbabilityList​(List<Double> branchProbabilities)
        Sums the probabilities of the list of probabilities. In a list of summed probabilities, each value of an element in the list has its own probability added by the previous probability. Means, if the the first probabilities in the list of probabilities is 0.3, the value of the first element in the summed probability list is 0.3. If the second probabilities in the list of probabilities is 0.4, the corresponding value in the summed probability list is 0.4+0.3 and so on.
        Parameters:
        branchProbabilities - a list with branch probabilities.
        Returns:
        the summed probability list.

      • determineBranchTransition

        public org.palladiosimulator.pcm.usagemodel.BranchTransition determineBranchTransition​(EList<org.palladiosimulator.pcm.usagemodel.BranchTransition> branchTransitions)
        Determines a branch transition out of a list of branch transitions, with respect to their probabilities.
        Parameters:
        branchTransitions - the list of branch transition.
        Returns:
        a branch transition.

      • determineProbabilisticBranchTransition

        public org.palladiosimulator.pcm.seff.ProbabilisticBranchTransition determineProbabilisticBranchTransition​(EList<org.palladiosimulator.pcm.seff.AbstractBranchTransition> probabilisticBranchTransitions)
        Determines a probabilistic branch transition out of a list of probabilistic branch transitions, with respect to their probabilities.
        Parameters:
        probabilisticBranchTransitions - the list of probabilistic branch transition.
        Returns:
        a probabilistic branch transition.

      • determineTransition

        public org.palladiosimulator.pcm.seff.AbstractBranchTransition determineTransition​(EList<org.palladiosimulator.pcm.seff.AbstractBranchTransition> abstractBranchTransitions)
        Determines a branch transition in the list of branch transitions. The list can only contains either probabilistic or guarded branch transitions.
        Parameters:
        abstractBranchTransitions - the list with branch transitions.
        Returns:
        the determined AbstractBranchTransition.

      • extractProbabiltiesRDSEFF

        protected List<Double> extractProbabiltiesRDSEFF​(EList<org.palladiosimulator.pcm.seff.AbstractBranchTransition> probabilisticBranchTransitions)
        Extracts the probabilities of a list of ProbabilisticBranchTransition.
        Parameters:
        probabilisticBranchTransitions - the list of ProbabilisticBranchTransition.
        Returns:
        a list only containing the probabilities.

      • extractProbabiltiesUsageModel

        protected List<Double> extractProbabiltiesUsageModel​(EList<org.palladiosimulator.pcm.usagemodel.BranchTransition> branchTransitions)
        Extracts the probabilities of a list of BranchTransition.
        Parameters:
        branchTransitions - the list of BranchTransition.
        Returns:
        a list only containing the probabilities.
