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.
RangePredicate	Defines a common contract for range-like predicates.
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 conversion of the attribute's value.
AbstractVisitor	Base class for all visitors.
AndPredicate	And Predicate
BetweenPredicate	Between Predicate
BoundedRangePredicate	Range predicate that is bounded on both sides.
CompositeEqualPredicate	Does the same thing as EqualPredicate but for composite indexes and values.
CompositeIndexVisitor	Optimizes single-attribute predicates into composite index predicates.
CompositeRangePredicate	Does the same thing as GreaterLessPredicate, BetweenPredicate and BoundedRangePredicate but for composite indexes and values.
EmptyOptimizer	Optimizer which just returns the original predicate.
EqualPredicate	Equal Predicate
EvaluatePredicate	Wraps a predicate for which Index.canEvaluate(java.lang.Class<? extends com.hazelcast.query.Predicate>) returned true.
EvaluateVisitor	Tries to divide the predicate tree into isolated subtrees every of which can be evaluated by Index.evaluate(com.hazelcast.query.Predicate) method in a single go.
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
PredicateUtils
QueryOptimizerFactory	Creates QueryOptimizer according to HazelcastProperties configuration.
RangeVisitor	Performs range predicates optimization.
RegexPredicate	Regex Predicate
RuleBasedQueryOptimizer	Rule based optimizer.
