Examples of org.geotools.data.crs.ReprojectFeatureReader

org.geotools.data.crs.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 ); 
```

      FeatureReader<SimpleFeatureType, SimpleFeature> newfr = reader;
        if (query != null && query.getMaxFeatures() != Integer.MAX_VALUE){
            newfr = new MaxFeatureReader<SimpleFeatureType, SimpleFeature>(newfr, query.getMaxFeatures());
        }
      if (this.reproject != null){
          newfr = new ReprojectFeatureReader(newfr, (SimpleFeatureType) featureType, this.reproject);
      }
      //creates a re-type feature reader
      if (this.newFeatureType != null && !this.newFeatureType.equals(this.featureType)){
        newfr = new ReTypeFeatureReader(newfr, (SimpleFeatureType)this.newFeatureType);
