std::map< uint32_t, Ptr< RemoteChannelBundle > > RemoteChannelMap
Simulation virtual time values and global simulation resolution.
Definition: nstime.h:102
Smart pointer class similar to boost::intrusive_ptr.
Definition: ptr.h:73
#define NS_ASSERT(condition)
At runtime, in debugging builds, if this condition is not true, the program prints the source file...

static NullMessageSimulatorImpl * GetInstance(void)
int64x64_t Min(const int64x64_t &a, const int64x64_t &b)
Minimum.
Definition: int64x64.h:197
static void InitializeNullMessageEvents(void)
Setup initial Null Message events for every RemoteChannelBundle.
static void Destroy(void)
Destroy the singleton.
Every class exported by the ns3 library is enclosed in the ns3 namespace.
static Ptr< RemoteChannelBundle > Find(uint32_t systemId)
static Ptr< RemoteChannelBundle > Add(uint32_t systemId)
Add RemoteChannelBundle from this task to MPI task on other side of the link.
void ScheduleNullMessageEvent(Ptr< RemoteChannelBundle > bundle)
static Time GetMaximumSimulationTime(void)
Get the maximum representable simulation time.
