Class ReprojectingFilterVisitor

Object

DuplicatingFilterVisitor

ReprojectingFilterVisitor

All Implemented Interfaces:

ExpressionVisitor, FilterVisitor

public class ReprojectingFilterVisitor
extends DuplicatingFilterVisitor

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 PropertyName, and the second always a Literal
