      • isNegated

        boolean isNegated​()
        Whether the predicate has been created from another predicate by applying the Predicate.not() method or the CriteriaBuilder.not() method.
        boolean indicating if the predicate is a negated predicate
      • getExpressions

        java.util.List<Expression<java.lang.Boolean>> getExpressions​()
        Return the top-level conjuncts or disjuncts of the predicate. Returns empty list if there are no top-level conjuncts or disjuncts of the predicate. Modifications to the list do not affect the query.
        list of boolean expressions forming the predicate
