ObjectReprojectFeatureReader
public class ReprojectFeatureReader
ReprojectFeatureReader provides a reprojection for FeatureTypes.
ReprojectFeatureReader is a wrapper used to reproject GeometryAttributes to a user supplied CoordinateReferenceSystem from the original CoordinateReferenceSystem supplied by the original FeatureReader.
Example Use:
ReprojectFeatureReader reader =
new ReprojectFeatureReader( originalReader, reprojectCS );
CoordinateReferenceSystem originalCS =
originalReader.getFeatureType().getDefaultGeometry().getCoordinateSystem();
CoordinateReferenceSystem newCS =
reader.getFeatureType().getDefaultGeometry().getCoordinateSystem();
assertEquals( reprojectCS, newCS );
TODO: handle the case where there is more than one geometry and the other
geometries have a different CS than the default geometry

public ReprojectFeatureReader(FeatureReader<SimpleFeatureType,SimpleFeature> reader, SimpleFeatureType schema, MathTransform transform)
Please note schema is that of the expected results, You may need to use FeatureTypes.transform( FeatureType, crs ) to create the schema provider.
