PessimisticLockScope.EXTENDED - JPA enum constant
In addition to the behavior for
PessimisticLockScope.NORMAL, element collections and relationships owned by the entity that are contained in join tables will be locked if the
javax.persistence.lock.scope property is specified with a value of
PessimisticLockScope.EXTENDED. The state of entities referenced by such relationships will not be locked (unless those entities are explicitly locked). Locking such a relationship or element collection generally locks only the rows in the join table or collection table for that relationship or collection. This means that phantoms will be possible.
- Since:
- JPA 2.0
