Examples with OneToOne jakarta.persistence.OneToOne used on opensource projects

Example 1 with OneToOne

use of jakarta.persistence.OneToOne in project hibernate-orm by hibernate.

the class JPAXMLOverriddenAnnotationReader method getOneToOne.

/**
 * As per section 12.2 of the JPA 2.0 specification, the association
 * subelements (many-to-one, one-to-many, one-to-one, many-to-many,
 * element-collection) completely override the mapping for the specified
 * field or property.  Thus, any methods which might in some contexts merge
 * with annotations must not do so in this context.
 *
 * @see #getElementCollection(List, XMLContext.Default)
 */
