Member Function Documentation

◆ Cancel()

void ns3::DefaultSimulatorImpl::Cancel ( const EventId & id )

overridevirtual

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

[in] id the event to cancel

Implements ns3::SimulatorImpl.

Here is the call graph for this function:

◆ Destroy()

void ns3::DefaultSimulatorImpl::Destroy ( )

overridevirtual

Execute the events scheduled with ScheduleDestroy().

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, Simulator::Schedule and Simulator::ScheduleWithContext.

Implements ns3::SimulatorImpl.

Definition at line 79 of file default-simulator-impl.cc.

References m_destroyEvents, NS_LOG_FUNCTION, and NS_LOG_LOGIC.

◆ DoDispose()

void ns3::DefaultSimulatorImpl::DoDispose ( )

overrideprivatevirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::Object.

References ns3::Object::DoDispose(), ns3::Scheduler::Event::impl, m_events, NS_LOG_FUNCTION, ProcessEventsWithContext(), and ns3::SimpleRefCount< T, PARENT, DELETER >::Unref().

Here is the call graph for this function:

◆ GetContext()

uint32_t ns3::DefaultSimulatorImpl::GetContext ( ) const

overridevirtual

Get the current simulation context.

The simulation context is the ns-3 notion of a Logical Process. Events in a single context should only modify state associated with that context. Events for objects in other contexts should be scheduled with ScheduleWithContext() to track the context switches. In other words, events in different contexts should be mutually thread safe, by not modify overlapping model state.

In circumstances where the context can't be determined, such as during object initialization, the enum value NO_CONTEXT should be used.

Returns: The current simulation context

Here is the caller graph for this function:

◆ GetDelayLeft()

Time ns3::DefaultSimulatorImpl::GetDelayLeft ( const EventId & id ) const

overridevirtual

Get the remaining time until this event will execute.

Parameters

[in] 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.

Implements ns3::SimulatorImpl.

Definition at line 293 of file default-simulator-impl.cc.

References IsExpired(), and m_currentTs.

Here is the call graph for this function:

◆ GetEventCount()

uint64_t ns3::DefaultSimulatorImpl::GetEventCount ( ) const

overridevirtual

Get the number of events executed.

Returns: The total number of events executed.

Implements ns3::SimulatorImpl.

Definition at line 384 of file default-simulator-impl.cc.

References m_eventCount.

◆ GetMaximumSimulationTime()

Time ns3::DefaultSimulatorImpl::GetMaximumSimulationTime ( ) const

overridevirtual

Get the maximum representable simulation time.

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.

Implements ns3::SimulatorImpl.

Definition at line 372 of file default-simulator-impl.cc.

◆ GetSystemId()

uint32_t ns3::DefaultSimulatorImpl::GetSystemId ( ) const

overridevirtual

Get the system id of this simulator.

The system id is the identifier for this simulator instance in a distributed simulation. For MPI this is the MPI rank.

Returns: The system id for this simulator.

Implements ns3::SimulatorImpl.

Definition at line 113 of file default-simulator-impl.cc.

◆ GetTypeId()

TypeId ns3::DefaultSimulatorImpl::GetTypeId ( )

static

Register this type.

Returns: The object TypeId.

Here is the caller graph for this function:

◆ IsExpired()

bool ns3::DefaultSimulatorImpl::IsExpired ( const EventId & id ) const

overridevirtual

Check if an event has already run or been cancelled.

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 executed, which means that if the code executed by the event calls this function, it will get true.

Parameters

[in] id The event to test for expiration.

Returns: true if the event has expired, false otherwise.

Here is the caller graph for this function:

◆ IsFinished()

bool ns3::DefaultSimulatorImpl::IsFinished ( ) const

overridevirtual

Check if the simulation should finish.

Reasons to finish are because there are no more events lefts to be scheduled, or if simulation time has already reached the "stop time" (see Simulator::Stop()).

Returns: true if no more events or stop time reached.

void ns3::DefaultSimulatorImpl::Remove ( const EventId & id )
