Definition: object.h:88
The SimulatorImpl base class.
virtual EventId ScheduleDestroy(EventImpl *event)=0

virtual uint32_t GetSystemId() const =0
Get the system id of this simulator.
virtual EventId Schedule(const Time &delay, EventImpl *event)=0
Schedule a future event execution (in the same context).
static TypeId GetTypeId(void)
Get the registered TypeId for this class.
virtual void Destroy()=0
Execute the events scheduled with ScheduleDestroy().
virtual bool IsExpired(const EventId &id) const =0
Check if an event has already run or been cancelled.
virtual void Run(void)=0
Run the simulation.
virtual void Remove(const EventId &id)=0
Remove an event from the event list.

virtual void Stop(void)=0
Tell the Simulator the calling event should be the last one executed.
virtual bool IsFinished(void) const =0
Check if the simulation should finish.
virtual uint64_t GetEventCount(void) const =0
Get the number of events executed.
