Class AbstractFeature

java.lang.Object

oracle.spatial.network.nfe.vis.maps.geoobject.AbstractFeature

All Implemented Interfaces:

java.lang.Cloneable, GeoObject

Direct Known Subclasses:

GeometryFeature

public abstract class AbstractFeature
extends java.lang.Object
implements GeoObject

Defines an abstract class that represents a geospatial feature. A feature is defined by a spatial attribute and a set of non-complex (and non-spatial) attributes. Each spatial type, must extend this abstract class. Examples of features include geometry feature, annotation text feature, and topology feature.
