All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.concurrent.Future<java.lang.Void>, Freezable

Direct Known Subclasses:

GLM2.GLMGrid.DeleteGridTsk, GLM2.GLMGrid.UnlockGridTsk, GLMModel.DeleteModelTask, GLMModel.GetScoringModelTask, GLMModel.UnlockModelTask

Enclosing class:

DTask<T extends DTask>

public abstract static class DTask.DKeyTask<T extends DTask.DKeyTask,V extends Iced>
extends DTask<DTask.DKeyTask>

Task to be executed at home of the given key. Basically a wrapper around DTask which enables us to bypass remote/local distinction (RPC versus submitTask).

Method Detail

map

protected abstract void map(V v)

compute2

public final void compute2()

Specified by:

compute2 in class H2O.H2OCountedCompleter

onCompletion

public void onCompletion(jsr166y.CountedCompleter cc)

Description copied from class: jsr166y.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 jsr166y.CountedCompleter

Parameters:

cc - the task invoking this method (which may be this task itself).

submitTask

public void submitTask()

forkTask

public void forkTask()

invokeTask

public T invokeTask()
