Class NFEFeature

java.lang.Object

oracle.spatial.network.nfe.model.NFEBasicModelObject

oracle.spatial.network.nfe.model.feature.NFEFeature

All Implemented Interfaces:

NFEModelObject

Direct Known Subclasses:

NFEBasicFeature

public abstract class NFEFeature
extends NFEBasicModelObject

This is the base class for representing a single network feature in memory. A feature must belong to a feature layer, otherwise, it is considered a standalone feature. When a feature belongs to a feature layer, any change to a feature property is notified to its parent feature layer. Also, any change notified from a feature's feature element, is notified to the feature layer.
