Detailed Description

A region stores all objects in a specific part of the map. It stores streets, nodes and vehicles.

Constructor & Destructor Documentation

vanetsim.map.Region.Region	(	int	x,
		int	y,
		int	leftBoundary,
		int	rightBoundary,
		int	upperBoundary,
		int	lowerBoundary
	)

inline

Constructor for a region.

Parameters

x	the position on the x axis of the new region
y	the position on the y axis of the new region
leftBoundary	the coordinate of the left boundary
rightBoundary	the coordinate of the right boundary
upperBoundary	the coordinate of the upper boundary

Member Function Documentation

void vanetsim.map.Region.addMixZone	(	Node	node,
		int	radius
	)

inline

adds mix zone at the location of "node" if no mix zone on this location already exists

Node vanetsim.map.Region.addNode	(	Node	node,
		boolean	doCheck
	)

inline

Function to add a node to this region.

Parameters

node	the node to add
doCheck	`true` if a check should be made if this node already exists; else `false` to skip the test

Returns: the node added (might be different from node if it already existed and check was true)

void vanetsim.map.Region.addRSU ( RSU rsu )

inline

Function to add a Road-Side-Units to this region.

Parameters

rsu	the RSU to add

void vanetsim.map.Region.addStreet	(	Street	street,
		boolean	doCheck
	)

inline

Function to add a street to this region. This also checks if it is intersecting with other streets in this region and sets the appropriate flag on the streets!

Parameters

street	the street to add
doCheck	`true` if a check should be made if this street already exists; else `false` to skip the test

synchronized void vanetsim.map.Region.addVehicle	(	Vehicle	vehicle,
		boolean	doCheck
	)

inline

Function to add a vehicle to this region.

Parameters

vehicle	vehicle to add
doCheck	`true` if a check should be made if this vehicle already exists; else `false` to skip the test

void vanetsim.map.Region.calculateJunctions ( )

inline

This function should be called before starting simulation. All nodes calculate if they are junctions and and what their priority streets are. Furthermore, mixing zones are generated.

void vanetsim.map.Region.checkStreetsForBridges ( )

inline

Checks all streets in this region for possible bridges.

void vanetsim.map.Region.cleanVehicles ( )

inline

This function should be called before initializing a new scenario to delete all vehicles.

void vanetsim.map.Region.clearMixZones ( )

inline

clear all mix zones from this region.

void vanetsim.map.Region.clearRSUs ( )

inline

clear all RSUs from this region.

void vanetsim.map.Region.clearTrafficLights ( )

inline

This function deletes all traffic lights in this region

void vanetsim.map.Region.createBacklink	(	WorkerThread	thread,
		int	numberinThread
	)

inline

Creates a backlink to the worker thread which computes this region.

Parameters

thread	the thread
numberinThread	the number in the thread

void vanetsim.map.Region.deleteMixZone ( Node node )

inline

deletes mix zone at the node

Parameters

node	Node where mix zone is placed on

void vanetsim.map.Region.delNode ( Node node )

inline

Delete a node.

Parameters

node the node

void vanetsim.map.Region.delRSU ( RSU rsu )

inline

Delete a Road-Side-Unit.

Parameters

rsu	the RSU to delete

void vanetsim.map.Region.delStreet ( Street street )

inline

Delete a street.

Parameters

street the street

synchronized void vanetsim.map.Region.delVehicle ( Vehicle vehicle )

inline

Function to delete a vehicle from this region.

Parameters

vehicle the vehicle to remove

String [] vanetsim.map.Region.getIntersectionPoints	(	Node	mixNode,
		Region	region12
	)

inline

Gets intersection points between mix-zone and streets. Before evoking check if this node is a mix-zone. Note that the performance of this function is very bad. It has to be evoked before the start of the simulation!

Returns: string array with to intersection String in form of "x1:x2:x3"

int vanetsim.map.Region.getLeftBoundary ( )

inline

Gets the coordinate of the left boundary of this region.

Returns: the coordinate

int vanetsim.map.Region.getLowerBoundary ( )

inline

Gets the coordinate of the lower boundary of this region.

Returns: the coordinate

Node [] vanetsim.map.Region.getMixZoneNodes ( )

inline

Returns all mix zone nodes in this region.

Returns: an array containing all nodes

Node [] vanetsim.map.Region.getNodes ( )

inline

Returns all nodes in this region.

Returns: an array containing all nodes

int vanetsim.map.Region.getRightBoundary ( )

inline

Gets the coordinate of the right boundary of this region.

Returns: the coordinate

RSU [] vanetsim.map.Region.getRSUs ( )

inline

Returns all Road-Side-Units in this region.

Returns: an array containing all RSUs

Street [] vanetsim.map.Region.getStreets ( )

inline

Returns all streets in this region.

Returns: an array containing all streets

int vanetsim.map.Region.getUpperBoundary ( )

inline

Gets the coordinate of the upper boundary of this region.

Returns: the coordinate

Vehicle [] vanetsim.map.Region.getVehicleArray ( )

inline

Creates an array as a copy of the vehicle ArrayList to prevent problems during simulation caused by changing the ArrayList while reading it in another thread. The array is cached so that new ones are only created when needed.

Returns: the array copy of all vehicles in this region or an empty array if there are no elements

ArrayList<Vehicle> vanetsim.map.Region.getVehicleArrayList ( )

inline

Used to return the ArrayList of all vehicles. Note that it can not guaranteed, that no changes are made after you received this.

Returns: the ArrayList containing all vehicles

int vanetsim.map.Region.getX ( )

inline

Function to get the x axis position of this region.

Returns: x axis position

int vanetsim.map.Region.getY ( )

inline

Function to get the y axis position of this region.

Returns: y axis position

void vanetsim.map.Region.prepareLogs ( Node[] nodes )

inline

Method to prepare the log files. Calculates all intersections beetween streets and mix-zones
