getOperator
Predicate.BooleanOperator getOperator()
Return the boolean operator for the predicate. If the predicate is simple, this isAND
.- Returns:
- boolean operator for the predicate
-
isNegated
boolean isNegated()
Whether the predicate has been created from another predicate by applying thePredicate.not()
method or theCriteriaBuilder.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
