work

public int work()

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

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).
