virtual void DoDispose(void)
The dispose method.
virtual Vector DoGetVelocity(void) const
Returns the current velocity of a node.
bool m_lazyNotify
If true, course change updates are only notified when position is calculated.
void AddWaypoint(const Waypoint &waypoint)
Vector m_velocity
The current velocity vector.
virtual Vector DoGetPosition(void) const
Get current position.
std::deque< Waypoint > m_waypoints
The double ended queue containing the ns3::Waypoint objects.
Keep track of the current position and velocity of an object.
bool m_first
This variable is set to true if there are no waypoints in the std::deque.
virtual void DoSetPosition(const Vector &position)
Sets a new position for the node.
void Update(void) const
Update the underlying state corresponding to the stored waypoints.
static TypeId GetTypeId(void)
Register this type with the TypeId system.
Waypoint m_next
The next ns3::Waypoint in the deque.
void EndMobility(void)
Clear any existing waypoints and set the current waypoint time to infinity.
Waypoint m_current
The ns3::Waypoint currently being used.
Waypoint-based mobility model.
WaypointMobilityModel()
Create a path with no waypoints at location (0,0,0).
Waypoint GetNextWaypoint(void) const
Get the waypoint that this object is traveling towards.
a unique identifier for an interface.
Definition: type-id.h:58
a (time, location) pair.
Definition: waypoint.h:35
bool m_initialPositionIsWaypoint
If true, calling SetPosition with no waypoints creates a waypoint.
uint32_t WaypointsLeft(void) const
Get the number of waypoints left for this object, excluding the next one.
