Method Detail

canRun

public boolean canRun()

Overrides:

canRun in class ModelingStep<M extends hex.Model>

Returns:

true iff we can call ModelingStep.run() on this modeling step to start a new job.

startJob

protected water.Job<M> startJob()

Description copied from class: ModelingStep

Starts a new Job as part of this step.

Specified by:

startJob in class ModelingStep<M extends hex.Model>

Returns:

the newly started job.

getJobType

protected WorkAllocations.JobType getJobType()

Specified by:

getJobType in class ModelingStep<M extends hex.Model>

makeKey

protected water.Key<Models> makeKey(java.lang.String name,
                                    boolean withCounter)

Overrides:

makeKey in class ModelingStep<M extends hex.Model>

iterateSubSteps

public java.util.Iterator<? extends ModelingStep> iterateSubSteps()

Overrides:

iterateSubSteps in class ModelingStep<M extends hex.Model>

Returns:

an Iterator for the potential sub-steps provided by this modeling step.

getSubStep

protected java.util.Optional<? extends ModelingStep> getSubStep(java.lang.String id)

Overrides:

getSubStep in class ModelingStep<M extends hex.Model>

Returns:

the sub-step (if any) with the given identifier, or null if there's no sub-step
