factory

protected transient SessionFactoryImpl factory
Constructor Detail

AbstractSessionImpl

protected AbstractSessionImpl(SessionFactoryImpl factory,
                              String tenantIdentifier)
Method Detail

getFactory

public SessionFactoryImplementor getFactory()
Description copied from interface: SessionImplementor
Get the creating SessionFactoryImplementor

Specified by:
getFactory in interface SessionImplementor

getTransactionEnvironment

public TransactionEnvironment getTransactionEnvironment()
Description copied from interface: TransactionContext
Obtain the TransactionEnvironment associated with this context.

Specified by:
getTransactionEnvironment in interface TransactionContext
Returns:
The transaction environment.

execute

public <T> T execute(LobCreationContext.Callback<T> callback)
Description copied from interface: LobCreationContext
Execute the given callback, making sure it has access to a viable JDBC Connection.

Specified by:
execute in interface LobCreationContext
Parameters:
callback - The callback to execute .
Returns:
The LOB created by the callback.

isClosed

public boolean isClosed()
Description copied from interface: SessionImplementor
Determine whether the session is closed. Provided separately from SessionImplementor.isOpen() as this method does not attempt any JTA synchronization registration, where as SessionImplementor.isOpen() does; which makes this one nicer to use for most internal purposes.

Specified by:
isClosed in interface SessionImplementor
Specified by:
isClosed in interface TransactionContext
Returns:
True if the session is closed; false otherwise.

setClosed

protected void setClosed()

errorIfClosed

protected void errorIfClosed()

public Query getNamedSQLQuery(String queryName)
                       throws MappingException
Description copied from interface: SessionImplementor
Get a Query instance for a named native SQL query

Specified by:
getNamedSQLQuery in interface SessionImplementor
