Examples with JoinType javax.persistence.criteria.JoinType used on opensource projects

Example 1 with JoinType

use of javax.persistence.criteria.JoinType in project stdlib by petergeneric.

the class JPAJoin method join.

public JPAJoin join(final String relation) {
    final QRelation rel = entity.getRelation(relation);
    final JoinType joinType;
    // For non-nullable non-collection joins, use an INNER join instead of a LEFT join
    if (!rel.isNullable() && !rel.isCollection())
        joinType = JoinType.INNER;
    else
        joinType = JoinType.LEFT;
    final Join<Object, Object> join = root.join(relation, joinType);
    return new JPAJoin(builder, rel, join, rel.isCollection());
}

Example 2 with JoinType

use of javax.persistence.criteria.JoinType in project crnk-framework by crnk-project.

the class JoinRegistry method getOrCreateJoin.

private F getOrCreateJoin(MetaAttributePath srcPath, MetaAttribute targetAttr) {
    MetaAttributePath path = srcPath.concat(targetAttr);
    F parent = joinMap.get(srcPath);
    F join = joinMap.get(path);
    if (join == null) {
        JoinType joinType = query.getJoinType(path);
        join = backend.doJoin(targetAttr, joinType, parent);
        joinMap.put(path, join);
    }
    return join;
}

Example 3 with JoinType

use of javax.persistence.criteria.JoinType in project hibernate-orm by hibernate.

the class SingularAttributeJoinTest method testEntityModeMapJoins.

/**
 * When building a join from a non-class based entity (EntityMode.MAP), make sure you get the Bindable from
 * the SingularAttribute as the join model. If you don't, you'll get the first non-classed based entity
 * you added to your configuration. Regression for HHH-9142.
