|
* An {@link ExecutorService} for running {@link ForkJoinTask}s. |
| 523 |
|
* Lifecycle control. The low word contains the number of workers |
| 524 |
|
* that are (probably) executing tasks. This value is atomically |
| 525 |
|
* incremented before a worker gets a task to run, and decremented |
| 526 |
< |
* when worker has no tasks and cannot find any. Bits 16-18 |
| 526 |
> |
* when a worker has no tasks and cannot find any. Bits 16-18 |
| 527 |
|
* contain runLevel value. When all are zero, the pool is |
| 528 |
|
* running. Level transitions are monotonic (running -> shutdown |
| 529 |
|
* -> terminating -> terminated) so each transition adds a bit. |
