public interface ExpressionVisitor
Visitor with visit methods to be called by Expression.accept(...).

Please note that a generic visit( Expression ) entry point has not been provided, although Expression forms a heirarchy for your convience it is not an open heirarchy. If you need to extend this system please make use of {code Function}, this will allow extention while remaining standards complient.

It is very common for a single instnace to implement both ExpressionVisitor and FilterVisitor.

GeoAPI 2.0
