Interface LogicExpr.UniverseGenerator

Enclosing interface:

LogicExpr

public static interface LogicExpr.UniverseGenerator

Special interface for universe generation. If logic expressions are used for selection of fulfilling elements in a universe, certain operations might need the complete universe as a set. Instances of this interface can deliver it, e.g. by doing certain database queries. An implementation should keep in mind that it might be time- and/or space-consuming. Therefore, it should implement some kind of caching algorithm. Logic expressions must not change the result returned by generateUniverse().

Method Summary
