|
* ForkJoinWorkerThreads are managed by ForkJoinPools and perform |
| 26 |
|
* ForkJoinTasks. For explanation, see the internal documentation |
| 27 |
|
* of class ForkJoinPool. |
| 28 |
+ |
* |
| 29 |
+ |
* This class just maintains links to its pool and WorkQueue. The |
| 30 |
+ |
* pool field is set immediately upon construction, but the |
| 31 |
+ |
* workQueue field is not set until a call to registerWorker |
| 32 |
+ |
* completes. This leads to a visibility race, that is tolerated |
| 33 |
+ |
* by requiring that the workQueue field is only accessed by the |
| 34 |
+ |
* owning thread. |
