Constructor Detail

AccuracyScorerNodeView

public AccuracyScorerNodeView(AccuracyScorerNodeModel nodeModel)
Creates a new ScorerNodeView displaying the table with the score. The view consists of the table with the example data and the appropriate scoring in the upper part and the summary of correct and wrong classified examples in the lower part.

Parameters:
nodeModel - the underlying NodeModel
Method Detail

modelChanged

public void modelChanged()
Method is invoked when the underlying NodeModel has changed. Also the HiLightHandler have changed. Note, the NodeModel content may be not available. Be sure to modify GUI components in the EventDispatchThread only.

Specified by:
modelChanged in class AbstractNodeView<AccuracyScorerNodeModel>

onClose

protected void onClose()
Invoked when the window is about to be closed. Unregister HiLiteListeners. Dispose internal members.
This method is the first to be called on a close request (right after the view is unregistered from the NodeModel

Specified by:
onClose in class NodeView<AccuracyScorerNodeModel>

onOpen

protected void onOpen()
Invoked when the window has been opened. Register property listeners.
This method is called last on view construction - right before the components are made visible. It is not called on re-opening.

Specified by:
onOpen in class NodeView<AccuracyScorerNodeModel>

createHiLiteMenuItems

Collection<JMenuItem> createHiLiteMenuItems()
Helper function to create new JMenuItems that are in the hilite menu.

Returns:
all those items in an array

hiLite

public void hiLite(KeyEvent event)
Invoked when some item(s) were hilit.

Specified by:
hiLite in interface HiLiteListener
Parameters:
event - contains a list of row keys that were hilit

getNodeModel

protected AccuracyScorerNodeModel getNodeModel()
Get reference to underlying NodeModel, never null.

Overrides:
getNodeModel in class AbstractNodeView<AccuracyScorerNodeModel>
Returns:
NodeModel reference.

unHiLite

public void unHiLite(KeyEvent event)
Checks for all hilit cells the model. If a key noted as unhilit in the event occurs in a hilit cell the cell is unhilit (principle of correctness!!) Invoked when some item(s) were unhilit.

Specified by:
unHiLite in interface HiLiteListener
Parameters:
event - contains a list of row keys that were unhilit

unHiLiteAll

public void unHiLiteAll(KeyEvent event)
Invoked, when everything (all rows) are unhilit.

Specified by:
unHiLiteAll in interface HiLiteListener
Parameters:
event - contains a list of row key that were unhilit
