All Implemented Interfaces:

java.util.EventListener, javax.swing.event.ChangeListener, NFEModelListener, BehavioralLayer, FeatureSelectableLayer, SelectionEditableLayer, GeoObjectLayer, HoverableLayer, Layer, SelectableLayer

Direct Known Subclasses:

NFEManipulableFeatureLayerRenderer

public class NFEFeatureLayerRenderer
extends NFERenderer<NFEFeatureElementGeoObject>
implements NFEModelListener, FeatureSelectableLayer, SelectionEditableLayer

MapCanvas Layer implementation for rendering an NFE feature layer. It is automatically subscribed for listening its network's and feature layer's events to reflect the state and show the same elements with the same properties. Additionally to the basic selection feature provided by the basic NFERenderer, it allows selecting features as a whole (all the feature's feature elements are selected)
