Class 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.
