Constructor Detail

CompoundPredicate

public CompoundPredicate(CriteriaBuilderImpl criteriaBuilder,
                         javax.persistence.criteria.Predicate.BooleanOperator operator)

Constructs an empty conjunction or disjunction.

Parameters:

criteriaBuilder - The query builder from which this originates.

operator - Indicates whether this predicate will function as a conjunction or disjunction.

CompoundPredicate

public CompoundPredicate(CriteriaBuilderImpl criteriaBuilder,
                         javax.persistence.criteria.Predicate.BooleanOperator operator,
                         javax.persistence.criteria.Expression<Boolean>... expressions)

Constructs a conjunction or disjunction over the given expressions.

Parameters:

criteriaBuilder - The query builder from which this originates.

operator - Indicates whether this predicate will function as a conjunction or disjunction.

expressions - The expressions to be grouped.
