Constructor Detail

• ForkJoinWorkerThread

  protected ForkJoinWorkerThread(ForkJoinPool pool)

  Creates a ForkJoinWorkerThread operating in the given pool.

  Parameters:

  pool - the pool this thread works in

  Throws:

  NullPointerException - if pool is null

Method Detail

• getPool

  public ForkJoinPool getPool()

  Returns the pool hosting this thread.

  Returns:

  the pool

• getPoolIndex

  public int getPoolIndex()

  Returns the index number of this thread in its pool. The returned value ranges from zero to the maximum number of threads (minus one) that have ever been created in the pool. This method may be useful for applications that track status or collect results per-worker rather than per-task.

  Returns:

  the index number

• onStart

  protected void onStart()

  Initializes internal state after construction but before processing any tasks. If you override this method, you must invoke super.onStart() at the beginning of the method. Initialization requires care: Most fields must have legal default values, to ensure that attempted accesses from other threads work correctly even before this thread starts processing tasks.

• onTermination

  protected void onTermination(Throwable exception)

  Performs cleanup associated with termination of this worker thread. If you override this method, you must invoke super.onTermination at the end of the overridden method.

  Parameters:

  exception - the exception causing this thread to abort due to an unrecoverable error, or null if completed normally

• run

  public void run()

  This method is required to be public, but should never be called explicitly. It performs the main run loop to execute ForkJoinTasks.

  Specified by:

  run in interface Runnable

  Overrides:

  run in class Thread
