Examples with Criteria org.hibernate.Criteria used on opensource projects

Example 41 with Criteria

use of org.hibernate.Criteria in project hibernate-orm by hibernate.

the class CriteriaJoinWalker method generateTableAlias.

@Override
protected String generateTableAlias(int n, PropertyPath path, Joinable joinable) {
    // TODO: deal with side-effects (changes to includeInResultRowList, userAliasList, resultTypeList)!!!
    // for collection-of-entity, we are called twice for given "path"
    // once for the collection Joinable, once for the entity Joinable.
    // the second call will/must "consume" the alias + perform side effects according to consumesEntityAlias()
    // for collection-of-other, however, there is only one call 
    // it must "consume" the alias + perform side effects, despite what consumeEntityAlias() return says
    // 
    // note: the logic for adding to the userAliasList is still strictly based on consumesEntityAlias return value
    boolean checkForSqlAlias = joinable.consumesEntityAlias();
    if (!checkForSqlAlias && joinable.isCollection()) {
        // is it a collection-of-other (component or value) ?

Example 42 with Criteria

use of org.hibernate.Criteria in project hibernate-orm by hibernate.

the class CriteriaQueryTranslator method createCriteriaEntityNameMap.

private void createCriteriaEntityNameMap() {
    // initialize the rootProvider first
    final CriteriaInfoProvider rootProvider = new EntityCriteriaInfoProvider((Queryable) sessionFactory.getEntityPersister(rootEntityName));
    criteriaInfoMap.put(rootCriteria, rootProvider);
    nameCriteriaInfoMap.put(rootProvider.getName(), rootProvider);

        criteriaInfoMap.put(value, info);
        nameCriteriaInfoMap.put(info.getName(), info);
    }
}

Example 43 with Criteria

use of org.hibernate.Criteria in project hibernate-orm by hibernate.

the class CriteriaQueryTranslator method getEntityName.

//TODO: use these in methods above
@Override

Example 44 with Criteria

use of org.hibernate.Criteria in project hibernate-orm by hibernate.

the class CriteriaQueryTranslator method getWholeAssociationPath.

private String getWholeAssociationPath(CriteriaImpl.Subcriteria subcriteria) {
    String path = subcriteria.getPath();

    // aliased path, or a path rooted at the creating criteria instance

        // otherwise, recurse
        return getWholeAssociationPath((CriteriaImpl.Subcriteria) parent) + '.' + path;

        Criteria criteria = s.createCriteria(Citizen.class);
