Class SubFeatureState

java.lang.Object
  org.geotools.feature.collection.FeatureState
      org.geotools.feature.collection.SubFeatureState

public class SubFeatureState

extends FeatureState

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 backed by an origional FeatureCollection.

To use cut&paste the following code exactly:

 
 TBA
 
 

 

 On the bright side this means we can "fix" all the SubFeatureCollection
 implementationsin one fell-swoop.
