Method Detail

lcompute

public final void lcompute()

Inhale the data, build a DataAdapter and kick-off the computation.

Specified by:

lcompute in class DRemoteTask

reduce

public final void reduce(DRemoteTask drt)

Specified by:

reduce in class DRemoteTask

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 DTask

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.

postGlobal

protected void postGlobal()

Overrides:

postGlobal in class DRemoteTask
