Class LiteralDemultiplyingFilterVisitor

Object

DuplicatingFilterVisitor

LiteralDemultiplyingFilterVisitor

All Implemented Interfaces:

ExpressionVisitor, FilterVisitor

public class LiteralDemultiplyingFilterVisitor
extends DuplicatingFilterVisitor

This visitor gets rid of equations that contain literals with multiple values (collections) and creates instead multiple singe value equations, replacing the ANY, ALL, ONE logic by AND, OR, NOT logic
