#define NS_OBJECT_ENSURE_REGISTERED(type)
Register an Object subclass with the TypeId system.
Definition: object-base.h:45
Vector GetCurrentPosition(void) const
Get current position vector.
virtual void DoSetPosition(const Vector &position)
Keep track of the current position and velocity of an object.
void Update(void) const
Update position, if not paused, from last position and time of last update.
Every class exported by the ns3 library is enclosed in the ns3 namespace.
static TypeId GetTypeId(void)
Register this type with the TypeId system.
void SetVelocity(const Vector &vel)
Set new velocity vector.
ConstantVelocityMobilityModel()
Create position located at coordinates (0,0,0) with speed (0,0,0).
void NotifyCourseChange(void) const
Must be invoked by subclasses when the course of the position changes to notify course change listene...
Vector GetVelocity(void) const
Get velocity; if paused, will return a zero vector.
void Unpause(void)
Resume mobility from current position at current velocity.
