  • getOperator

    Predicate.BooleanOperator getOperator()

    Return the boolean operator for the predicate. If the predicate is simple, this is AND.

    Returns:

    boolean operator for the predicate

  • isNegated

    boolean isNegated()

    Whether the predicate has been created from another predicate by applying the Predicate.not() method or the CriteriaBuilder.not() method.

    Returns:

    boolean indicating if the predicate is a negated predicate

  • getExpressions

    List<Expression<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.

    Returns:

    list of boolean expressions forming the predicate

  • not

    Predicate not()

    Create a negation of the predicate.

    Returns:

    negated predicate
