```
public double runFor(double interval)
```
    Description copied from interface: Simulation
    
    Runs the simulation for a specific period of time and then immediately returns. In order to complete the whole simulation you need to invoke this method multiple times Note: Should be used only in the synchronous mode (after starting the simulation with Simulation.startSync()).
    
    Specified by:
    
    runFor in interface Simulation
    
    Parameters:
    
    interval - The interval for which the simulation should be run (in seconds)
    
    Returns:
    
    Clock at the end of simulation interval (in seconds)
  - start
```
public double start()
```
    Description copied from interface: Simulation
    
    Starts simulation execution and waits for all entities to finish, i.e. until all entities threads reach non-RUNNABLE state or there are no more events in the future event queue.
    Note: This method should be called only after all the entities have been setup and added. The method blocks until the simulation is ended.
    
    Specified by:
    
    start in interface Simulation
    
    Returns:
    
    the last clock time

    Description copied from interface: Simulation
    
    Starts simulation execution in synchronous mode, retuning immediately. You need to call Simulation.runFor(double) method subsequently to actually process simulation steps. Note: This method should be called only after all the entities have been setup and added. The method returns immediately after preparing the internal state of the simulation.

  - terminateAt
```
public boolean terminateAt(double time)
```
    Description copied from interface: Simulation
    
    Schedules the termination of the simulation for a given time (in seconds).

If no event happens, the clock is increased to simulate time passing. The clock increment is defined according to: (i) the lower Datacenter.getSchedulingInterval() between existing Datacenters; or (ii) Simulation.getMinTimeBetweenEvents() in case no Datacenter has its schedulingInterval set.
    
    Specified by:
    
    terminateAt in interface Simulation
    
    Parameters:
    
    time - the time at which the simulation has to be terminated (in seconds)

    Description copied from interface: Simulation
    
    Adds an EventListener object that will be notified when the simulation is paused. When this Listener is notified, it will receive an EventInfo informing the time the pause occurred.
    This object is just information about the event that happened. In fact, it isn't generated an actual SimEvent for a pause event because there is not need for that.
    
    Specified by:
    
    addOnSimulationPauseListener in interface Simulation
    
    Parameters:
    
    listener - the event listener to add
    
    Returns:
  - addOnSimulationStartListener
```
public final Simulation addOnSimulationStartListener(EventListener<EventInfo> listener)
```
    Specified by:
    
    addOnSimulationStartListener in interface Simulation
  - removeOnSimulationPauseListener
```
public boolean removeOnSimulationPauseListener(EventListener<EventInfo> listener)
```
    Description copied from interface: Simulation
    
    Removes a listener from the onSimulationPausedListener List.
    
    Specified by:
    
    removeOnSimulationPauseListener in interface Simulation
    
    Parameters:
    
    listener - the listener to remove
    
    Returns:
    
    true if the listener was found and removed, false otherwise
  - addOnEventProcessingListener
```
public final Simulation addOnEventProcessingListener(EventListener<SimEvent> listener)
```
    Description copied from interface: Simulation
    
    Adds a EventListener object that will be notified when any event is processed by CloudSim. When this Listener is notified, it will receive the SimEvent that was processed.
    
    Specified by:
    
    addOnEventProcessingListener in interface Simulation
    
    Parameters:
    
    listener - the event listener to add
    
    Returns:
  - removeOnEventProcessingListener
```
public boolean removeOnEventProcessingListener(EventListener<SimEvent> listener)
```
    Description copied from interface: Simulation
    
    Removes a listener from the onEventProcessingListener List.
    
    Specified by:
    
    removeOnEventProcessingListener in interface Simulation
    
    Parameters:
    
    listener - the listener to remove
    
    Returns:
    
    true if the listener was found and removed, false otherwise
  - addOnClockTickListener
```
public Simulation addOnClockTickListener(EventListener<EventInfo> listener)
```
    Description copied from interface: Simulation
    
    Adds a EventListener object that will be notified every time when the simulation clock advances. Notifications are sent in a second interval to avoid notification flood. Thus, if the clock changes, for instance, from 1.0, to 1.1, 2.0, 2.1, 2.2, 2.5 and then 3.2, notifications will just be sent for the times 1, 2 and 3 that represent the integer part of the simulation time.
    
    Specified by:
    
    addOnClockTickListener in interface Simulation
    
    Parameters:
    
    listener - the event listener to add
    
    Returns:
  - removeOnClockTickListener
```
public boolean removeOnClockTickListener(EventListener<? extends EventInfo> listener)
```
    Description copied from interface: Simulation
    
    Removes a listener from the onClockTickListener List.
    
    Specified by:
    
    removeOnClockTickListener in interface Simulation
    
    Parameters:
    
    listener - the listener to remove
    
    Returns:
    
    true if the listener was found and removed, false otherwise
  - getNetworkTopology
```
public NetworkTopology getNetworkTopology()
```
    Description copied from interface: Simulation
    
    Gets the network topology used for Network simulations.
    
    Specified by:
    
    getNetworkTopology in interface Simulation
    
    Returns:
  - setNetworkTopology
```
public void setNetworkTopology(NetworkTopology networkTopology)
```
    Description copied from interface: Simulation
    
    Sets the network topology used for Network simulations.
    
    Specified by:
    
    setNetworkTopology in interface Simulation
    
    Parameters:
    
    networkTopology - the network topology to set
  - getLastCloudletProcessingUpdate
```
public double getLastCloudletProcessingUpdate()
```
    Description copied from interface: Simulation
    
    Gets the last time (in seconds) some Cloudlet was processed in the simulation.
    
    Specified by:
    
    getLastCloudletProcessingUpdate in interface Simulation
  - setLastCloudletProcessingUpdate
```
public void setLastCloudletProcessingUpdate(double lastCloudletProcessingUpdate)
```
    Description copied from interface: Simulation
    
    Sets the last time (in seconds) some Cloudlet was processed in the simulation.
    
    Specified by:
    
    setLastCloudletProcessingUpdate in interface Simulation
