Constructor Detail

ALPrequentialEvaluationTask

public ALPrequentialEvaluationTask()

Constructor which sets the color coding to black.

ALPrequentialEvaluationTask

public ALPrequentialEvaluationTask(java.awt.Color colorCoding)

Constructor with which a color coding can be set.

Parameters:

colorCoding - the color used by the task

Method Detail

getPurposeString

public java.lang.String getPurposeString()

Description copied from class: AbstractOptionHandler

Dictionary with option texts and objects

Specified by:

getPurposeString in interface OptionHandler

Overrides:

getPurposeString in class AbstractOptionHandler

Returns:

the string with the purpose of this object

getTaskResultType

public java.lang.Class<?> getTaskResultType()

Description copied from interface: Task

Gets the result type of this task. Tasks can return LearningCurve, LearningEvaluation, Classifier, String, Instances..

Returns:

a class object of the result of this task

doMainTask

protected java.lang.Object doMainTask(TaskMonitor monitor,
                                      ObjectRepository repository)

Description copied from class: MainTask

This method performs this task. AbstractTask implements doTask, that uses doTaskImpl. MainTask implements doTaskImpl using doMainTask so its extensions only need to implement doMainTask.

Specified by:

doMainTask in class MainTask

Parameters:

monitor - the TaskMonitor to use

repository - the ObjectRepository to use

Returns:

an object with the result of this task

getSubtaskThreads

public java.util.List<ALTaskThread> getSubtaskThreads()

Description copied from class: MetaMainTask

Get the list of threads for all subtasks and recursively the children's subtasks.

Specified by:

getSubtaskThreads in class ALMainTask

Returns:

list of subtask threads, recursively generated
