Class FeatureRef<T extends IFeature>

java.lang.Object

org.vast.ogc.xlink.SimpleLink<T>

org.vast.ogc.xlink.CachedReference<T>

org.vast.ogc.gml.FeatureRef<T>

Type Parameters:

T - Target Feature Type

All Implemented Interfaces:

IFeature, IXlinkReference<T>, IResource

Direct Known Subclasses:

ObservationRef, ProcedureRef

public class FeatureRef<T extends IFeature>
extends CachedReference<T>
implements IFeature

Wrapper class for use when an IFeature object is or can be included by reference. This enables fetching and instantiating the target object lazily.
