Examples of org.geotools.data.collection.CollectionFeatureSource

org.geotools.data.collection.CollectionFeatureSource
This is a "port" of ContentFeatureSource to work with an iterator.
To use this class please "wrap" CollectionFeatureSource around your choice of FeatureCollection.
```
 SimpleFeatureCollection collection = new ListFeatureCollection(schema); collection.add(feature1); collection.add(feature2); FeatureSource source = new CollectionFeatureSource(collection); 
```
Note to implementors: If you are performing "real I/O" please use ContentFeatureSource as it provides support for IOException. @author Jody @source $URL$
