Returns:
The contract for accessing JDBC connections.

                          String entityOrRoleName)
Hide the changing requirements of cache key creation.

Parameters:
id - The entity identifier or collection key.
type - The type
entityOrRoleName - The entity name or collection role.
Returns:
The cache key

getInterceptor

Interceptor getInterceptor()
Retrieves the interceptor currently in use by this event source.

Returns:
The interceptor.

setAutoClear

void setAutoClear(boolean enabled)
Enable/disable automatic cache clearing from after transaction completion (for EJB3)


disableTransactionAutoJoin

void disableTransactionAutoJoin()
Disable automatic transaction joining. The really only has any effect for CMT transactions. The default Hibernate behavior is to auto join any active JTA transaction (register Synchronization). JPA however defines an explicit join transaction operation. See javax.persistence.EntityManager#joinTransaction


isTransactionInProgress

boolean isTransactionInProgress()
Does this Session have an active Hibernate transaction or is there a JTA transaction in progress?


initializeCollection

void initializeCollection(PersistentCollection collection,
                          boolean writing)
                          throws HibernateException
Initialize the collection (if not already initialized)

Throws:
HibernateException

internalLoad

                    throws HibernateException
Load an instance without checking if it was deleted. When nullable is disabled this method may create a new proxy or return an existing proxy; if it does not exist, throw an exception. When nullable is enabled, the method does not create new proxies (but might return an existing proxy); if it does not exist, return null. When eager is enabled, the object is eagerly fetched

Throws:
HibernateException

immediateLoad

Object immediateLoad(String entityName,
                     Serializable id)
                     throws HibernateException
