Package com.hazelcast.query.impl.predicates

Interface Summary

Interface	Description
CompoundPredicate	Interface for predicates which operate on an array of sub-predicates.
NegatablePredicate	Predicates can implement this interface if they can convert itself into logical negation
QueryOptimizer	Optimizes predicate for faster execution.
Visitor	Visitor can inspect internal state of a node, but it's not allowed to mutate its internal state.

Class Summary

Class	Description
AbstractIndexAwarePredicate<K,V>
AbstractPredicate<K,V>	Provides base features for predicates, such as extraction and convertion of the attribute's value.
AbstractVisitor	Base class for all visitors.
AndPredicate	And Predicate
BetweenPredicate	Between Predicate
BetweenVisitor	Replaces expression from (age >= X and age <= Y) into (age between X Y) It detects some predicates which are trivally false.
EmptyOptimizer	Optimizer which just returns the original predicate.
EqualPredicate	Equal Predicate
FlatteningVisitor	Rewrites predicates: 1.
GreaterLessPredicate	Greater Less Predicate
ILikePredicate	Ilike Predicate
InPredicate	In Predicate
InstanceOfPredicate	Predicate version of `instaceof` operator from Java.
LikePredicate	Like Predicate
NotEqualPredicate	Not Equal Predicate
NotPredicate	Not Predicate
OrPredicate	Or Predicate
OrToInVisitor	Transforms predicate (attribute = 1 or attribute = 2 or attribute = 3) into (attribute in (1, 2, 3) InPredicate is easier to evaluate in both indexed and non-indexed scenarios.
PredicateDataSerializerHook
QueryOptimizerFactory	Creates QueryOptimizer according to HazelcastProperties configuration.
RegexPredicate	Regex Predicate
RuleBasedQueryOptimizer	Rule based optimizer.
