simulate

public void simulate(SimulationService simulationService,
                     SimulationItem simulationItem)
              throws RemoteException

Description copied from interface: SimulatorLauncher

Execute une simulation.

Specified by:

simulate in interface SimulatorLauncher

Parameters:

simulationService - le SimulationService qui a initie la simulation

simulationItem - l'item contenant toutes les infos nécessaire au lancement de la simulation IMPORTANT Quoi qu'il arrive

Throws:

RemoteException - Si pour l'execution de la simulation on utilise des resources distantes (serveurs) et que ceux si non pas pu etre contacte. Dans ce cas la simulation n'a pas ete faite et cette exception est levee.

maxSimulationThread

public int maxSimulationThread()

Description copied from interface: SimulatorLauncher

Retourne le nombre maximal de thread de simulations simultanées supporté.

Specified by:

maxSimulationThread in interface SimulatorLauncher

Returns:

un nombre superieur a 0

getCheckProgressionInterval

public int getCheckProgressionInterval()

Description copied from interface: SimulatorLauncher

Retourne l'intervalle de temps a utiliser entre deux verification de progresssion.

Specified by:

getCheckProgressionInterval in interface SimulatorLauncher

Returns:

intervalle (en secondes);

message

protected void message(SimulationControl control,
                       String message)

Display both message on UI (listeners and log).

Parameters:

control -

message -

subProcessSimulate

public SimulationStorage subProcessSimulate(SimulationControl control,
                                            File simulationZip,
                                            String simulationPrescript)
                                     throws Exception

Throws:

Exception

getSimulationStorage

public SimulationStorage getSimulationStorage(SimulationService simulationService,
                                              SimulationControl control)
                                       throws RemoteException

Description copied from interface: SimulatorLauncher

Retourne le storage où est stockée la simulation.

Specified by:

getSimulationStorage in interface SimulatorLauncher

Parameters:

simulationService - le SimulationService qui a initie la simulation

control - le control de la simulation

Returns:

le storage contenant la simulation qui vient d'etre faite ou null en fait au lieu de faire une seul simulation, plusieurs ou ete faite par exemple tout un plan d'analyse. Cette classe est tout de meme responsable du stockage de chaque simulation dans des storages.

Throws:

RemoteException - Si pour l'execution de la simulation on utilise des resources distantes (serveurs) et que ceux si non pas pu etre contacte.

updateControl

public void updateControl(SimulationService simulationService,
                          SimulationControl control)
                   throws RemoteException

Description copied from interface: SimulatorLauncher

Met à jour la progression.

Specified by:

updateControl in interface SimulatorLauncher

Parameters:

simulationService - le SimulationService qui a initie la simulation

control - le control de la simulation

Throws:

RemoteException - Si pour l'execution de la simulation on utilise des resources distantes (serveurs) et que ceux si non pas pu etre contacte.

simulationStopRequest

public void simulationStopRequest(SimulationJob job)

Called if a started simulation has been ask to stop. Tell launcher to stop simulation if possible. Do nothing (no restriction on subprocess launcher).

Specified by:

simulationStopRequest in interface SimulatorLauncher

Parameters:

job - job to stop
