virtual void ns3::SimulatorImpl::Cancel ( const EventId &  ev  )  [pure virtual]

Set the cancel bit on this event: the event's associated function will not be invoked when it expires. This method has the same visible effect as the ns3::Simulator::remove method but its algorithmic complexity is much lower: it has O(1) complexity. This method has the exact same semantics as ns3::EventId::cancel. Note that it is not possible to cancel events which were scheduled for the "destroy" time. Doing so will result in a program error (crash).

Parameters:
ev the event to cancel

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual void ns3::SimulatorImpl::Destroy (  )  [pure virtual]

Every event scheduled by the Simulator::insertAtDestroy method is invoked. Then, we ensure that any memory allocated by the Simulator is freed. This method is typically invoked at the end of a simulation to avoid false-positive reports by a leak checker. After this method has been invoked, it is actually possible to restart a new simulation with a set of calls to Simulator::run and Simulator::insert_*.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual uint32_t ns3::SimulatorImpl::GetContext ( void   )  const [pure virtual]
Returns:
the current simulation context

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual Time ns3::SimulatorImpl::GetDelayLeft ( const EventId &  id  )  const [pure virtual]
Parameters:
id the event id to analyse
Returns:
the delay left until the input event id expires. if the event is not running, this method returns zero.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual Time ns3::SimulatorImpl::GetMaximumSimulationTime ( void   )  const [pure virtual]
Returns:
the maximum simulation time at which an event can be scheduled.

The returned value will always be bigger than or equal to Simulator::Now.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual uint32_t ns3::SimulatorImpl::GetSystemId (  )  const [pure virtual]
Returns:
the system id for this simulator; used for MPI or other distributed simulations

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

Reimplemented from ns3::Object.

Reimplemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual bool ns3::SimulatorImpl::IsExpired ( const EventId &  ev  )  const [pure virtual]

This method has O(1) complexity. Note that it is not possible to test for the expiration of events which were scheduled for the "destroy" time. Doing so will result in a program error (crash). An event is said to "expire" when it starts being scheduled which means that if the code executed by the event calls this function, it will get true.

Parameters:
ev the event to test for expiration
Returns:
true if the event has expired, false otherwise.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual bool ns3::SimulatorImpl::IsFinished ( void   )  const [pure virtual]

If there are no more events lefts to be scheduled, or if simulation time has already reached the "stop time" (see Simulator::Stop()), return true. Return false otherwise.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual Time ns3::SimulatorImpl::Next ( void   )  const [pure virtual]

If Simulator::IsFinished returns true, the behavior of this method is undefined. Otherwise, it returns the microsecond-based time of the next event expected to be scheduled.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual Time ns3::SimulatorImpl::Now ( void   )  const [pure virtual]

Return the "current simulation time".

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual void ns3::SimulatorImpl::Remove ( const EventId &  ev  )  [pure virtual]

Remove an event from the event list. This method has the same visible effect as the ns3::EventId::Cancel method but its algorithmic complexity is much higher: it has often O(log(n)) complexity, sometimes O(n), sometimes worse. Note that it is not possible to remove events which were scheduled for the "destroy" time. Doing so will result in a program error (crash).

Parameters:
ev the event to remove from the list of scheduled events.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual void ns3::SimulatorImpl::Run ( void   )  [pure virtual]

Run the simulation until one of:

  • no events are present anymore
  • the user called Simulator::stop
  • the user called Simulator::stopAtUs and the expiration time of the next event to be processed is greater than or equal to the stop time.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual void ns3::SimulatorImpl::RunOneEvent ( void   )  [pure virtual]

Process only the next simulation event, then return immediately.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual EventId ns3::SimulatorImpl::Schedule ( Time const &  time,
EventImpl *  event 
) [pure virtual]
Parameters:
time delay until the event expires
event the event to schedule
Returns:
a unique identifier for the newly-scheduled event.

This method will be typically used by language bindings to delegate events to their own subclass of the EventImpl base class.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual EventId ns3::SimulatorImpl::ScheduleDestroy ( EventImpl *  event  )  [pure virtual]
Parameters:
event the event to schedule
Returns:
a unique identifier for the newly-scheduled event.

This method will be typically used by language bindings to delegate events to their own subclass of the EventImpl base class.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual EventId ns3::SimulatorImpl::ScheduleNow ( EventImpl *  event  )  [pure virtual]
Parameters:
event the event to schedule
Returns:
a unique identifier for the newly-scheduled event.

This method will be typically used by language bindings to delegate events to their own subclass of the EventImpl base class.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual void ns3::SimulatorImpl::ScheduleWithContext ( uint32_t  context,
Time const &  time,
EventImpl *  event 
) [pure virtual]
Parameters:
time delay until the event expires
context event context
event the event to schedule
Returns:
a unique identifier for the newly-scheduled event.

This method will be typically used by language bindings to delegate events to their own subclass of the EventImpl base class.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual void ns3::SimulatorImpl::SetScheduler ( ObjectFactory  schedulerFactory  )  [pure virtual]
Parameters:
schedulerFactory a new event scheduler factory

The event scheduler can be set at any time: the events scheduled in the previous scheduler will be transfered to the new scheduler before we start to use it.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual void ns3::SimulatorImpl::Stop ( Time const &  time  )  [pure virtual]

Force the Simulator::run method to return to the caller when the expiration time of the next event to be processed is greater than or equal to the stop time. The stop time is relative to the current simulation time.

Parameters:
time the stop time, relative to the current time.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.

virtual void ns3::SimulatorImpl::Stop ( void   )  [pure virtual]

If an event invokes this method, it will be the last event scheduled by the Simulator::run method before returning to the caller.

Implemented in ns3::DistributedSimulatorImpl, ns3::DefaultSimulatorImpl, and ns3::RealtimeSimulatorImpl.
