```
public abstract class ViewEventFeaturesListener
extends org.apache.wicket.ajax.AbstractDefaultAjaxBehavior
```
Provides a behavior that invokes a callback event whenever the map view changes. Specifically, this behavior will monitor the map's ol.View for 'center' and 'resolution' events. In addition to providing information on the current view, it will also provide all of the features in the view extent for the provided layer.
