Examples of org.geotools.filter.spatial.ReprojectingFilterVisitor

org.geotools.filter.spatial.ReprojectingFilterVisitor
Returns a clone of the provided filter where all geometries and bboxes have been reprojected to the CRS of the associated attributes. The working assumption is that the filters specified are strictly compliant with the OGC spec, so the first item is always a {@link PropertyName}, and the second always a {@link Literal} @author Andrea Aime - The Open Planning Project @source $URL$
