int64_t AssignStreams(int64_t stream)
Assign a fixed random variable stream number to the random variables used by this model...
Smart pointer class similar to boost::intrusive_ptr.

virtual Vector DoGetPosition(void) const =0
double GetRelativeSpeed(Ptr< const MobilityModel > other) const
def start()
Definition: core.py:1855
Forward calls to a chain of Callback.
virtual ~MobilityModel()=0
Keep track of the current position and velocity of an object.
ns3::TracedCallback< Ptr< const MobilityModel > > m_courseChangeTrace
Used to alert subscribers that a change in direction, velocity, or position has occurred.
static TypeId GetTypeId(void)
Register this type with the TypeId system.
double GetDistanceFrom(Ptr< const MobilityModel > position) const
Every class exported by the ns3 library is enclosed in the ns3 namespace.
void SetPosition(const Vector &position)
void NotifyCourseChange(void) const
Must be invoked by subclasses when the course of the position changes to notify course change listene...
Vector GetPosition(void) const
virtual void DoSetPosition(const Vector &position)=0
A base class which provides memory management and object aggregation.
Definition: object.h:87
virtual Vector DoGetVelocity(void) const =0
virtual int64_t DoAssignStreams(int64_t start)
The default implementation does nothing but return the passed-in parameter.
a unique identifier for an interface.
