Criteria builder where clause

Question

I am trying to build a SQL where clause using criteriaBuilder and predicates to create some SQL like:

 WHERE
 (country5_.ctry_iso_cd = 'ESP'
AND datadomain6_.data_dmn_cd = 'MTH'
OR country5_.ctry_iso_cd = 'ESP'
AND datadomain6_.data_dmn_cd = 'SOU'
)
 AND NOT ( EXISTS (
     SELECT
         'NOT READY'
     FROM
         dc_dca_installation_status collection5_
     WHERE
         collection0_.installation_id = collection5_.installation_id
 ) )

the brackets around the list of AND OR pairs are important to separate them from the not exists. This is because of the AND having precedence what i get is

WHERE
 country5_.ctry_iso_cd = 'ESP'
AND datadomain6_.data_dmn_cd = 'MTH'
or country5_.ctry_iso_cd = 'ESP'
AND datadomain6_.data_dmn_cd = 'SOU'
AND NOT ( EXISTS (
     SELECT
         'NOT READY'
     FROM
         dc_dca_installation_status collection5_
     WHERE
         collection0_.installation_id = collection5_.installation_id
 ) )

I can build up all the predicates no problem but I just don't know how to get it to add the brackets in around the AND OR pairs list

the list of AND OR pairs are build like this into 1 list of predicates

 countryDomainPredicates.add(cb.and(
     cb.equal(countryJoin.get(Country_.ctryIsoCd), ud.getCountryCode()),
     cb.equal(dataDomainJoin.get(DataDomain_.code), ud.getDataDomainCode())

and the subquery is added like this

cb.not(cb.exists(subquery));

and the where

critQuery.where(cb.and(array));

Brackets around each AND OR pair would be just as good

Answer 1

I fixed it myself, instead of building up 1 array and converting that into 1 predicate.

i converted the array of AND OR pairs into 1 predicate, added the not exists into another predicate and then used this array of 2 predicates into the where.

List<Predicate> predicates = new ArrayList<>();
predicates.add( addAndOrPairs(cb, root, userDataDomains));
Subquery<String> subquery = createSubQuery(cb, root);
predicates.add(cb.and(cb.exists(subquery).not()));
critQuery.where(cb.and(predicates.toArray(new Predicate[predicates.size()])));
