Method Detail

getRawResult

public final V getRawResult()

Description copied from class: CountedCompleter

Returns the result of the computation. By default returns null, which is appropriate for Void actions, but in other cases should be overridden, almost always to return a field or function of a field that holds the result upon completion.

Overrides:

getRawResult in class CountedCompleter<V>

Returns:

the result of the computation

compute

public final void compute()

Description copied from class: CountedCompleter

The main computation performed by this task.

Specified by:

compute in class CountedCompleter<V>
