Examples with DiscriminatorSqmPath - org.hibernate.metamodel.model.domain.internal.DiscriminatorSqmPath

Example 1 with DiscriminatorSqmPath

use of org.hibernate.metamodel.model.domain.internal.DiscriminatorSqmPath in project hibernate-orm by hibernate.

the class BaseSqmToSqlAstConverter method createTreatTypeRestriction.

private Predicate createTreatTypeRestriction(SqmPath<?> lhs, Set<String> subclassEntityNames) {
    final MappingMetamodel domainModel = creationContext.getSessionFactory().getRuntimeMetamodels().getMappingMetamodel();
    // Do what visitSelfInterpretingSqmPath does, except for calling preparingReusablePath
    // as that would register a type usage for the table group that we don't want here
    final DiscriminatorSqmPath discriminatorSqmPath = (DiscriminatorSqmPath) lhs.type();
    registerTypeUsage(discriminatorSqmPath);
    final Expression typeExpression = discriminatorSqmPath.interpret(this, this, jpaQueryComplianceEnabled);
    if (subclassEntityNames.size() == 1) {
        return new ComparisonPredicate(typeExpression, ComparisonOperator.EQUAL, new EntityTypeLiteral(domainModel.findEntityDescriptor(subclassEntityNames.iterator().next())));
    } else {
        final List<Expression> typeLiterals = new ArrayList<>(subclassEntityNames.size());
        for (String subclassEntityName : subclassEntityNames) {
            typeLiterals.add(new EntityTypeLiteral(domainModel.findEntityDescriptor(subclassEntityName)));
        }
        return new InListPredicate(typeExpression, typeLiterals);
    }
}
