org.geotools.feature.iso.FeatureImpl
   org.geotools.feature.iso.collection.FeatureState

FeatureState
public class FeatureState extends FeatureImpl (Code)
This is *not* a Feature - it is a Delegate used by FeatureCollection implementations as "mix-in", provides implementation of featureCollection events, featureType, and attribute access.

To use cut&paste the following code exactly:

 
 
 

On the bright side this means we can "fix" all the FeatureCollection implementations in one fell-swoop.
