RevisionComparePresenter

java.lang.Object
- org.tweetyproject.beliefdynamics.gui.RevisionComparePresenter

All Implemented Interfaces:

java.awt.event.ActionListener, java.awt.event.ItemListener, java.util.EventListener, javax.swing.event.ChangeListener
```
public class RevisionComparePresenter
extends java.lang.Object
implements java.awt.event.ItemListener, javax.swing.event.ChangeListener, java.awt.event.ActionListener
```
This class couples the RevisionCompare 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.
