Class 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.
