[Java] Class AbstractForkJoinWorker

java.lang.Object
  jsr166y.RecursiveTask
      groovyx.gpars.forkjoin.AbstractForkJoinWorker

public abstract class AbstractForkJoinWorker
extends RecursiveTask

Implements the ForkJoin worker contract. Subclasses need to implement the compute() to perform the actual Fork/Join algorithm leveraging the options provided by the AbstractForkJoinWorker class. The AbstractForJoinWorker class takes care of the child sub-processes.

Method Detail

compute

@Override
protected final java.lang.Object compute()

computeTask

protected java.lang.Object computeTask()

forkOffChild

protected final void forkOffChild(AbstractForkJoinWorker child)

Forks a child task. Makes sure it has a means to indicate back completion. The worker is stored in the internal list of workers for evidence and easy result retrieval through getChildrenResults().

Parameters:: child - The child task

getChildrenResults

@SuppressWarnings({"unchecked"})
public final java.util.List getChildrenResults()

Waits for and returns the results of the child tasks.

Returns:: A list of results returned from the child tasks
