Interface XMethod

All Known Implementing Classes:

XMethodImpl

public interface XMethod

A method (actually a function - there is no object support yet) in the Sparqlify system. A method can be associated with - a SQL rewrite transformation - an invocable that performs the method. Examples: Intersection of geometries, for which no invocable is provided: boolean bif:intersects(geometry, geometry, precision_in_km): The big question is: should the SQL serializer be part of this class?
