PredicateMap

public class PredicateMultiMap
extends Object

Map that maps from a QueryPredicate of a query to a QueryPredicate of a MatchCandidate. The each mapping itself has other pieces of information associated with it:

• a PredicateMultiMap.ReapplyPredicateFunction which can be used to compensate the implied candidate predicate or
• a CorrelationIdentifier which denotes that this mapping binds the respective parameter in the match candidate
