* Uses a {@see EDU.oswego.cs.dl.util.concurrent.Sync} object
|
|
| 33 |
* for write operations. All other operations such as {@see #stop(long)}
|
|
| 34 |
* and {@see #stop} just do a normal java synchronization against the SynchornizedSynchChannel
|
|
| 35 |
* object instance. It is assumed that the Async message delivery is not
|
|
| 36 |
* concurrent and therefore does not require synchronization.
