* a one-shot action serving a variable number of parties. The typical |
| 89 |
|
* idiom is for the method setting this up to first register, then |
| 90 |
|
* start the actions, then deregister, as in: |
| 108 |
|
* int p = phaser.arriveAndDeregister(); // deregister self ... |
| 109 |
|
* p = phaser.awaitAdvance(p); // ... and await arrival |
| 110 |
|
* otherActions(); // do other things while tasks execute |
| 111 |
< |
* phaser.awaitAdvance(p); // awit final completion |
| 111 |
> |
* phaser.awaitAdvance(p); // await final completion |
| 112 |
|
* } |

* However, to efficiently maintain atomicity, these values are |
| 196 |
|
* packed into a single (atomic) long. Termination uses the sign |
| 197 |
|
* bit of 32 bit representation of phase, so phase is set to -1 on |
| 198 |
< |
* termination. Good performace relies on keeping state decoding |
