public class ReprojectFeatureResults extends AbstractFeatureCollection
ReprojectFeatureResults is a wrapper used to reproject GeometryAttributes to a user supplied CoordinateReferenceSystem from the original CoordinateReferenceSystem supplied by the original FeatureResults.
Example Use:
ReprojectFeatureResults results =
new ReprojectFeatureResults( originalResults, reprojectCS );
CoordinateReferenceSystem originalCS =
originalResults.getFeatureType().getDefaultGeometry().getCoordinateSystem();
CoordinateReferenceSystem newCS =
results.getFeatureType().getDefaultGeometry().getCoordinateSystem();
assertEquals( reprojectCS, newCS );

If you return an instance of FeatureIterator some effort is taken to call the FeatureIterator.close()
internally, however we cannot offer any assurance that client code
using AbstractFeatureCollection.iterator()
will perform the same check.

FeatureCollection
The order of traversal is dependent on the FeatureCollection implementation; some collections are able to make efficient use of an internal index in order to quickly visit features located in the same region.
