public class BaseFeatureState

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.

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.

Method Detail



featureType
public static FeatureType featureType(FeatureType schema)

Construct a fake FeatureType of this FeatureCollection.
 

 Unless a FeatureType was provided during consturction (or this method is
 overriden) a FeatureType will be generated based on getSchmea according
 to the following assumptions:
 

 
FeatureType is gml:AbstractFeatureCollectionType
 
first attribute is getSchema.typeName
 
the attribute FeatureType the same as returned by getSchema()
