public class CompoundPredicate extends AbstractPredicateImpl implements Serializable
predicate
is a grouping of other predicates
in order to convert
either a conjunction (logical AND) or a disjunction (logical OR).Predicate.BooleanOperator

Constructor and Description |
---|
CompoundPredicate(CriteriaBuilderImpl criteriaBuilder,
Predicate.BooleanOperator operator)
Constructs an empty conjunction or disjunction.
|
CompoundPredicate(CriteriaBuilderImpl criteriaBuilder,
Predicate.BooleanOperator operator,
Expression<Boolean>... expressions)
Constructs a conjunction or disjunction over the given expressions.
|
CompoundPredicate(CriteriaBuilderImpl criteriaBuilder,
Predicate.BooleanOperator operator,
List<Expression<Boolean>> expressions)
Constructs a conjunction or disjunction over the given expressions.

used when the predicate is wrapped in a negated wrapper. Allows passing
down the negation flag.
Note that this form is no-op in compound (junction) predicates. The reason being that compound predicates
are more complex and the negation is applied during its creation.render
