Class ReprojectFeatureReader

java.lang.Object
  org.geotools.data.crs.ReprojectFeatureReader

All Implemented Interfaces:

FeatureReader

public class ReprojectFeatureReader

extends java.lang.Object

implements FeatureReader

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
