Package de.uka.ipd.sdq.simucomframework

Class AbstractMain

  • All Implemented Interfaces:
    ISimulationControl, org.osgi.framework.BundleActivator
    public abstract class AbstractMain
extends Object
implements ISimulationControl, org.osgi.framework.BundleActivator
    Base class for simulation instances. It contains a generic simulation start and stop logic as well as basic error handling mechanisms. The code generated for each SimuCom instance contains the class main.SimuComControl that inherits from this one and provides the missing information. Excerpt from main.SimuComControl: public class SimuComControl extends de.uka.ipd.sdq.simucomframework.AbstractMain TODO This class currently serves too many concerns, e.g., creation of execution result calculators and mixing of usage response time calculator creation and handling of stop conditions. Therefore, some refactorings are needed. [Lehrig]

        Throws:
        Exception

      • run

        protected SimulationResult run​(IStatusObserver statusObserver,
                               SimuComConfig config,
                               boolean isRemoteRun)
        Run a simulation using the given configuration and report to the given observer
        Parameters:
        statusObserver - Observer to notify about the simulation's progress
        config - Configuration options for the simulation
        isRemoteRun - True if this simulation runs remotely and has no access to the local sensorframework
        Returns:
        A status code indicating success or failure of the simulation

      • stop

        protected void stop()
        Request a simulation stop

      • getModel

        public SimuComModel getModel()
        Returns:
        The simucom model used in this simulation run

      • getErrorThrowable

        public Throwable getErrorThrowable()
        Description copied from interface: ISimulationControl
        Returns an exception which caused the simulation to terminate in case of simulation errors as indicated by the SimuComResult returned by the startSimulation method
        Specified by:
        getErrorThrowable in interface ISimulationControl
        Returns:
        An error object in case an exception occurred during simulation execution

      • prepareSimulation

        public void prepareSimulation​(AbstractSimulationConfig config,
                              IStatusObserver observer,
                              boolean isRemoteRun)
        Description copied from interface: ISimulationControl
        Prepare a simulation run
        Specified by:
        prepareSimulation in interface ISimulationControl
        Parameters:
        config - The configuration object which sets many simulation parameters like stop conditions, storage location, etc.
        observer - An observer which gets notifications on the simulation progress
        isRemoteRun - If true, the simulation uses an own, temporary result store instead of the sensorfactory storage passed in the simulation parameter object. Use this for remote simulation docks which do not have access to the local sensor factory storages

      • startSimulation

        public SimulationResult startSimulation​(AbstractSimulationConfig config,
                                        IStatusObserver observer,
                                        boolean isRemoteRun)
        Description copied from interface: ISimulationControl
        Start a simulation run
        Specified by:
        startSimulation in interface ISimulationControl
        Parameters:
        config - The configuration object which sets many simulation parameters like stop conditions, storage location, etc.
        observer - An observer which gets notifications on the simulation progress
        isRemoteRun - If true, the simulation uses an own, temporary result store instead of the sensorfactory storage passed in the simulation parameter object. Use this for remote simulation docks which do not have access to the local sensor factory storages
        Returns:
        The result of the simulation run

      • getWorkloads

        protected abstract IWorkloadDriver[] getWorkloads​(SimuComConfig config,

        Template method pattern. Child classes have to implement this to return workload drivers to use in the simulation. The workload drivers are used to generate the simulated users.
        Parameters:
        config - the simulation configuration data
        Returns:
        Workload drivers to use in the simulation run
