Examples with PropertyData org.hibernate.envers.internal.entities.PropertyData used on opensource projects

Example 1 with PropertyData

use of org.hibernate.envers.internal.entities.PropertyData in project hibernate-orm by hibernate.

the class ToOneRelationMetadataGenerator method addToOne.

@SuppressWarnings({ "unchecked" })
void addToOne(Element parent, PropertyAuditingData propertyAuditingData, Value value, CompositeMapperBuilder mapper, String entityName, boolean insertable) {
    final String referencedEntityName = ((ToOne) value).getReferencedEntityName();
    final IdMappingData idMapping = mainGenerator.getReferencedIdMappingData(entityName, referencedEntityName, propertyAuditingData, true);
    final String lastPropertyPrefix = MappingTools.createToOneRelationPrefix(propertyAuditingData.getName());
    // Generating the id mapper for the relation
    final IdMapper relMapper = idMapping.getIdMapper().prefixMappedProperties(lastPropertyPrefix);
    // Storing information about this relation
    mainGenerator.getEntitiesConfigurations().get(entityName).addToOneRelation(propertyAuditingData.getName(), referencedEntityName, relMapper, insertable, MappingTools.ignoreNotFound(value));
    // If the property isn't insertable, checking if this is not a "fake" bidirectional many-to-one relationship,
    // that is, when the one side owns the relation (and is a collection), and the many side is non insertable.
    // When that's the case and the user specified to store this relation without a middle table (using
    // @AuditMappedBy), we have to make the property insertable for the purposes of Envers. In case of changes to
    // the entity that didn't involve the relation, it's value will then be stored properly. In case of changes
    // to the entity that did involve the relation, it's the responsibility of the collection side to store the
    // proper data.
    boolean nonInsertableFake;
    if (!insertable && propertyAuditingData.isForceInsertable()) {
        nonInsertableFake = true;

    // Adding an element to the mapping corresponding to the references entity id's
    final Element properties = (Element) idMapping.getXmlRelationMapping().clone();
    properties.addAttribute("name", propertyAuditingData.getName());
    MetadataTools.prefixNamesInPropertyElement(properties, lastPropertyPrefix, MetadataTools.getColumnNameIterator(value.getColumnIterator()), false, insertable);
