Class ReprojectFeatureIterator

Object

ReprojectFeatureIterator

All Implemented Interfaces:

Closeable, AutoCloseable, Iterator<SimpleFeature>, SimpleFeatureIterator, FeatureIterator<SimpleFeature>

public class ReprojectFeatureIterator
extends Object
implements Iterator<SimpleFeature>, SimpleFeatureIterator

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
