Method Detail

compute

public final void compute()

Description copied from class: jsr166y.CountedCompleter

The main computation performed by this task.

Specified by:

compute in class jsr166y.CountedCompleter

compute2

public abstract void compute2()

onExceptionalCompletion

public boolean onExceptionalCompletion(java.lang.Throwable ex,
                              jsr166y.CountedCompleter caller)

Description copied from class: jsr166y.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 jsr166y.CountedCompleter

Parameters:

ex - 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.

priority

public byte priority()

clone

public H2O.H2OCountedCompleter clone()

Overrides:

clone in class java.lang.Object
