Class PcmAction

  • Direct Known Subclasses:
    PcmProtoAction, PcmStubAction
    public abstract class PcmAction
extends Object
    Abstract class for implementing PCM actions, i.e., the behavior of components as specified via SEFFs. Refinements of this class could, for instance, add simulate stack frames for performance prototypes or provide code stub generation.

      • actions

        public String actions​(org.palladiosimulator.pcm.seff.AbstractAction action)
        Follows the action path and calls "action" for each action in it. Note that actions do not branch! Branching is solved by a BranchAction, therefore at most one successor is given at any time.

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.StartAction action)
        StartAction. Should be empty, I guess.

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.StopAction action)
        StopAction. Nothing to see here either.

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.CollectionIteratorAction action)
        No idea. We didn't implement this for the last ProtoCom either. FIXME Implement this as it is a crucial part of the bahavior (lehrig)

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.LoopAction action)
        LoopAction is transformed into a simple FOR statement.

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.ExternalCallAction action)
        ExternalCallAction calls a remote service.

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.InternalAction action)
        InteralAction uses a load generator to simulate CPU/HDD usage. Note that ProtoCom does NOT use InfrastructureCalls from the PCM model, because these should be reflected by the underlying middleware and OS!

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.BranchAction action)
        BranchAction is implemented as an IF condition. A BranchAction may have two different transition types: ProbabilisticBranchTransition and GuardedBranchTransition.

      • _branchTransition

        protected CharSequence _branchTransition​(org.palladiosimulator.pcm.seff.BranchAction action,
                                         org.palladiosimulator.pcm.seff.ProbabilisticBranchTransition transition)
        Branch transition for ProbabilisticBranchTransition entities.

      • _branchTransition

        protected CharSequence _branchTransition​(org.palladiosimulator.pcm.seff.BranchAction action,
                                         org.palladiosimulator.pcm.seff.GuardedBranchTransition transition)
        Branch transition for GuardedBranchTransition.

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.AcquireAction action)
        AcquireAction is mapped to the acquire method of Java Collection's semaphore implementation.

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.ReleaseAction action)

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.ForkAction action)
        A ForkAction spawns a new thread for each defined behavior. These should be processed asynchronously in parallel. Please note that manually spawning new threads is discouraged on certain middlewares (like JavaEE)!

      • _action

        protected String _action​(org.palladiosimulator.pcm.seff.EmitEventAction action)
        TODO Think about EmitEventAction. JMS?
