weka.core.AbstractInstance

weka.core.DenseInstance

weka.etplugin.DataInstance

All Implemented Interfaces:

Serializable, Copyable, Instance, RevisionHandler, TechnicalInformationHandler

public class DataInstance
extends DenseInstance
implements TechnicalInformationHandler

Wrapper class that stores the evaluation data of each classification performed alongside the graphical components to represent that evaluation in the Entropy Triangle. It handles the tooltip windows and the color of the DataPoints if the ActionListener is added, i.e., to the ColorBar.

Constructor Detail

DataInstance

public DataInstance(Instances dataset,
            double weight,
            double[] attValues)

Constructor that initializes instance variable with given values for the given dataset.

Parameters:

dataset - the Instances dataset that this instance belong

weight - the weight of this instance in the dataset

attValues - an array with the attributes values of this instance in double format

DataInstance

public DataInstance(Instances dataset,
            Instance instance)

Constructor that initializes instance variable with given values.

Parameters:

dataset - the Instances dataset that this instance belong

instance - the instance from which the attribute values and the weight are to be copied

Method Detail

setToolTips

public void setToolTips()

Sets and updates the tooltip windows of the DataPoints of this object. This method should be called when any of the information showed in the tooltip may have changed.

setColorChangeListener

public ActionListener setColorChangeListener(ColorBar colorBar)

Sets an ActionListener to sync the foreground color of the points of this instance in a graph with the given ColorBar.

Parameters:

colorBar - the object from where to get the new colors

Returns:

ActionListener the ActionListener that can be used by the ColorBar to change the color of the DataPoints of this DataInstance.

ColorBar

setPopupMenus

public void setPopupMenus(EntropyTrianglePanel etPanel)

Sets the right-click menu behavior for the points of this instance.

Parameters:

etPanel - the panel where the points of this instance is being drawn

copy

public Object copy()

Produces a shallow copy of this instance. The copy has access to the same dataset.

Specified by:

copy in interface Copyable

Overrides:

copy in class DenseInstance

Returns:

the shallow copy

getTechnicalInformation

public TechnicalInformation getTechnicalInformation()

Returns an instance of a TechnicalInformation object, containing detailed information about the technical background of this class, e.g., paper reference or book this class is based on.

Specified by:

getTechnicalInformation in interface TechnicalInformationHandler

Returns:

the technical information about this class
