                 float flength,
                 int lanecount)
Constructs the OFragment. OFragments are created on the GStreet panel. Once created, it will be added to an OStreet.

Method Detail

addVehicle

public void addVehicle(OVehicle car)
Adds OVehicle to the end of the queue. This method is not directly user accessable. Cars are added by the OFragment runTraffic method. The number of cars to be added is detailed in the GDensity panel.

exitVehicle

public void exitVehicle(int index)
Removes OVehicle from the queue. This method is not directly user accessable. Cars are removed by the OFragment runTraffic method. The number of cars to be removed is detailed in the GDensity panel.

getVehMPH

public int getVehMPH()
Gets the OFragment speed limit (works for KPH too).

setVehMPH

public void setVehMPH(int speed)
Sets the OFragment speed limit (works for KPH too).

getLanes

public int getLanes()
Gets the OFragment number of lanes

setLanes

public void setLanes(int lanes)
Sets the OFragment number of lanes

getSLth

public float getSLth()
Gets the OFragment length in seconds

setSLth

public final void setSLth(float slength)
Gets the OFragment length in seconds.

setFLth

public final void setFLth(float length)

getXLth

public float getXLth()
Gets the OFragment length in seconds in the X direction. This is needed for mapping the OFragment.

getYLth

public float getYLth()
Gets the OFragment length in seconds in the Y direction. This is needed for mapping the OFragment.

getPrevLoc

public float getPrevLoc()
Gets the location of the previous OVehicle within the OFragment. This method is used to tell if a car is too close to the car ahead of it.

public void setSSOrnt(double ornt)
Gets the OFragment orientation, or direction in degrees.

getSSOrnt

public double getSSOrnt()
Gets the OFragment orientation, or direction in degrees.

Gets the time till next car enters the OFragment. These are the number of tenth seconds (sec/10) that pass between vehicle entry events. These tenth seconds are entered on the GDensity panel.

setSDensity

public void setSDensity(int sdens)
Sets the time till next car enters the OFragment. These are the number of tenth seconds (sec/10) that pass between vehicle entry events. These tenth seconds are entered on the GDensity panel.

getEDensity

setEDensity

public void setEDensity(float edens)
Sets the OFragment exit density. Exits are entered as a % chance that a vehicle will leave.

isMapped

public boolean isMapped()
True if OFragment has been mapped. Once a fragment has been mapped it contains it's map coordinates and can be drawn on the map without further calculation.

setMapped

public void setMapped(boolean state)
Sets the OFragment mapped state. Once a fragment has been mapped it contains it's map coordinates and can be drawn on the map without further calculation.

getMapX1

public int getMapY1()
Gets the OFragment starting Y map coordinate.

getMapY2

public int getMapY2()
Gets the OFragment ending Y map coordinate.

setMapCoords

public void setMapCoords(int xx1,

                         int yy1,
                         int yy2)
Sets the OFragment starting and ending X and Y map coordinates. Due to the complexities of mapping, the words starting and ending may be somewhat relative.

getVehCount

public int getVehCount()
Gets the number of OVehicles contained in this OFragment.

useVeh

public OVehicle useVeh(int index)
Gets an OVehicle object from this OFragment.

runTraffic

public void runTraffic(OStreet sss)
Create, distroy, move and make turning decisions for OVehicles. Fragments at an intersection are numbered counter-clockwise. This method is called by the JavaDriver runTraffic method.

changeFrag

public void changeFrag(OVehicle veh,
                       OVehicle vehx,
                       OFragment fragx)
Moves an OVehicle from one OFragment to the next. The 'next' is determined before this method is called.
