Enclosing interface:

RelationalExpression

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public static interface RelationalExpression.CombinePredicate
```
A functional interface to combine the matches computed over pairs of quantifiers during matching into a boolean result (for the bound correlatedTo set handed into combine(com.apple.foundationdb.record.query.plan.temp.AliasMap, java.lang.Iterable<com.apple.foundationdb.record.query.plan.temp.AliasMap>)).

boolean combine(@Nonnull
                AliasMap boundCorrelatedToMap,
                @Nonnull
                Iterable<AliasMap> boundMapIterable)
```
    Combine the results of a Quantifiers.findMatches(com.apple.foundationdb.record.query.plan.temp.AliasMap, java.util.Collection<? extends com.apple.foundationdb.record.query.plan.temp.Quantifier>, java.util.Collection<? extends com.apple.foundationdb.record.query.plan.temp.Quantifier>, com.apple.foundationdb.record.query.plan.temp.matching.MatchPredicate<com.apple.foundationdb.record.query.plan.temp.Quantifier>) into a boolean result.
    
    Parameters:
    
    boundCorrelatedToMap - the bound correlated to map
    
    boundMapIterable - an iterable of AliasMap for all the matches for a given boundCorrelatedToMap
    
    Returns:
    
    false if the match should be dropped or true if it should be kept.
