public class WekaInstanceViewer
extends AbstractGraphicalDisplay
implements DisplayPanelProvider, TextSupplier

Actor for displaying adams.data.instance.Instance objects in a graphical way (using the internal format), like the 'Instance Explorer' tool.

Input/output:
- accepts:
weka.core.Instance
adams.data.instance.Instance

Valid options are:

-D <int> (property: debugLevel)

    as it is.
 

-stop-flow-on-error (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
