java.lang.Object org.hibernate.cache.jbc2.collection.TransactionalAccess org.hibernate.cache.jbc2.collection.OptimisticTransactionalAccess org.hibernate.cache.jbc2.collection.OptimisticReadOnlyAccess
public class OptimisticReadOnlyAccess
This defines the strategy for transactional access to collection data in an optimistic-locking JBossCache using its 2.x APIs.
The read-only access to a JBossCache really is still transactional, just with the extra semantic or guarantee that we will not update data.
Constructor Summary | |
---|---|
OptimisticReadOnlyAccess(CollectionRegionImpl region)
Create a new OptimisticReadOnlyAccess. |
Method Summary | |
