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..

Specified by:

getTaskResultType in interface Task

Returns:

a class object of the result of this task

doMainTask

public 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

defineImmutableCapabilities

public ImmutableCapabilities defineImmutableCapabilities()

Description copied from interface: CapabilitiesHandler

Defines the set of capabilities the object has. Should be overridden if the object's capabilities do not change.

Specified by:

defineImmutableCapabilities in interface CapabilitiesHandler

Overrides:

defineImmutableCapabilities in class ClassificationMainTask

Returns:

The capabilities of the object.
