    • normalizeRestriction

      public static @Nullable jakarta.persistence.criteria.Predicate normalizeRestriction(jakarta.persistence.criteria.Expression<Boolean> restriction)
      Normalizes the restriction of a criteria delete or update the same way as the one of a criteria query: an empty conjunction restricts nothing, an empty disjunction matches nothing and a junction of a single restriction is replaced by that restriction.
      Parameters:
      restriction - The restriction
      Returns:
      The normalized restriction or null if there is none
