org.geotools.filter
Interface SortBy2

All Superinterfaces:

SortBy, org.opengis.filter.sort.SortBy

public interface SortBy2

extends SortBy

GeoTools allows for more pervase use of Expression then is strictly supported by the specification.

To make the distiniction clear, generic use of Expression for SortBy has been issolated to this interface. You shoudl note that this is outside of the bounds of the Expression specification, and you will not be able to construct valid documents if you use any other expression then AttributeExpression.

Code that is compatible with the expanded use will indicate via acceptance of a SortBy2 parameter. If you are working with a strictly standards complient service (like WFS 1.1) it will be limited to the use of SortBy.
