Method Summary

Modifier and Type	Method and Description
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.

Method Detail

compute2

public void compute2()

Description copied from class: H2O.H2OCountedCompleter

Override compute3() with actual work without having to worry about tryComplete()

Overrides:

compute2 in class H2O.H2OCountedCompleter<FrameUtils.ExportTaskDriver>

onCompletion

public void onCompletion(CountedCompleter caller)

Description copied from class: CountedCompleter

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. By default, this method does nothing.

Overrides:

onCompletion in class CountedCompleter

Parameters:

caller - the task invoking this method (which may be this task itself).

onExceptionalCompletion

public boolean onExceptionalCompletion(java.lang.Throwable t,
                                       CountedCompleter caller)

Description copied from class: CountedCompleter

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. 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.

Overrides:

onExceptionalCompletion in class CountedCompleter

Parameters:

t - the exception

caller - the task invoking this method (which may be this task itself).

Returns:

true if this exception should be propagated to this tasks completer, if one exists.
