Class SimpleRevisionComparePresenter

java.lang.Object

net.sf.tweety.lp.asp.beliefdynamics.gui.SimpleRevisionComparePresenter

All Implemented Interfaces:

ActionListener, ItemListener, EventListener, ChangeListener

public class SimpleRevisionComparePresenter
extends Object
implements ItemListener, ChangeListener, ActionListener

This class couples the SimpleRevisionCompare View and Model, it needs to know the implementation used to load external belief base files, see FileHandler interface. The presenter reacts to user inputs on the view and proofs if the changes are valid and then delegates them to the model. It also registers the view as a PropertyListener to the correct model. This gui is based on the RevisionCompare gui from the beliefdynamics.gui package.
