Class WorkerThread

java.lang.Object
  java.lang.Thread
      vanetsim.simulation.WorkerThread

All Implemented Interfaces:

java.lang.Runnable

public final class WorkerThread
extends java.lang.Thread

This thread is meant to run parallel with multiple others to gain advantage of multiple CPUs. All simulation tasks are initiated from this class!

Constructor Detail

WorkerThread

public WorkerThread(Region[] ourRegions,
                    int timePerStep)

The main constructor for the worker thread. Don't use any other constructor inherited from the Thread class as all parameters are essential!

Parameters:

ourRegions - the regions which are assigned to us.

timePerStep - the time in milliseconds for one step

Method Detail

setBarriers

public void setBarriers(java.util.concurrent.CyclicBarrier barrierStart,
                        java.util.concurrent.CyclicBarrier barrierDuringWork,
                        java.util.concurrent.CyclicBarrier barrierFinish)

Set CyclicBarriers for thread synchronization.

Parameters:

barrierStart - the barrier for starting

barrierDuringWork - the barrier after adjusting the speed

barrierFinish - the barrier after completing all tasks

addChangedRegion

public void addChangedRegion(int i)

Adds a region to the list of changed region (so that it gets updated).

Parameters:

i - the number of the region in this thread

run

public void run()

The main method. All simulation is initiated from here!

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread
