com.nomagic.magicdraw.simulation.execution.SimulationExecutionListener is a listener for various events that can occur during execution of a model. 

	public class SimulationExecutionListener { 
        void configLoaded(Element config, SimulationExecution execution);   
        void executionStarted(SimulationExecution execution); 
        void beforeContextInitialized(SimulationExecution execution);
        void contextInitialized(SimulationExecution execution); 
        void executionTerminated(SimulationExecution execution);
        void elementActivated(Element element, Collection<?> values, ActivationContext context); 
		void elementDeactivated(Element element, Collection<?> values, ActivationContext context); 
		void eventTriggered(SignalInstance signal); 
		void operationCalled(Operation operation, List<ParameterValue> parameterValues, Object_ caller, Object_ target, boolean isSynchronous); 
		void behaviorCalled(Behavior behavior, List<ParameterValue> parameterValues, Object_ caller, Object_ target, boolean isSynchronous); 
		void objectCreated(Object_ sender, Object_ object); 
        void beforeObjectDestroyed(Object_ object)
        void valueChange(StructuredValue context, FeatureValue feature, Object oldValue, Object newValue)
        void objectStateActivated(StructuredValue context, State newState) 
		void busyStatusChange(StructuredValue context, Object oldValue, Object newValue);
    }
TEXT


To register a created execution listener to a global list, that ensures this listener to be added to each created SimulationExecution, use the following code:

SimulationManager.registerSimulationExecutionListener(listener); //listener is an instance of SimulationExecutionListener.
TEXT


If the SimulationExecution is already created, listener can be registered directly to that specific execution by calling the following:

Open APIFunction

SimulationManager.registerSimulationExecutionListener(SimulationExecutionListener listener, SimulationExecution execution)

Registers SimulationExecutionListener dynamically during the execution.

SimulationManager.unregisterSimulationExecutionListener(SimulationExecutionListener listener, SimulationExecution execution)

Unregisters SimulationExecutionListener.
