void |
compute2()
Override compute3() with actual work without having to worry about tryComplete()
|
void |
onCompletion(CountedCompleter caller)
Performs an action when method
CountedCompleter.tryComplete() is invoked
and there are no pending counts, or when the unconditional
method CountedCompleter.complete(java.lang.Void) is invoked. |
boolean |
onExceptionalCompletion(java.lang.Throwable t,
CountedCompleter caller)
Performs an action when method
ForkJoinTask.completeExceptionally(java.lang.Throwable)
is invoked or method CountedCompleter.compute() throws an exception, and
this task has not otherwise already completed normally. |

CountedCompleter
ForkJoinTask.completeExceptionally(java.lang.Throwable)
is invoked or method CountedCompleter.compute()
throws an exception, and
this task has not otherwise already completed normally. On
entry to this method, this task ForkJoinTask.isCompletedAbnormally()
. The return value of this
method controls further propagation: If true
and this
task has a completer, then this completer is also completed
exceptionally. The default implementation of this method does
nothing except return true
