geTransactionType

public TransactionType geTransactionType()

public TransactionStatus getStatus()

begin

public void begin()

Description copied from interface: Transactional

The TransactionManager.begin method starts a global transaction and associates the transaction context with the calling thread. If the TransactionManager implementation does not support nested transactions, the TransactionManager.begin method throws the NotSupportedException when the calling thread is already associated with a transaction. The TransactionManager.getTransaction method returns the Transaction object that represents the transaction context currently associated with the calling thread. This Transaction object can be used to perform various operations on the target transaction. Examples of Transaction object operations are resource enlistment and synchronization registration.

Specified by:

begin in interface Transactional

commit

public void commit()

Description copied from interface: Transactional

The TransactionManager.commit method completes the transaction currently associated with the calling thread. After the commit method returns, the calling thread is not associated with a transaction. If the commit method is called when the thread is not associated with any transaction context, the TransactionManager throws an exception. In some implementations, the commit operation is restricted to the transaction originator only. If the calling thread is not allowed to commit the transaction, the TransactionManager throws an exception.

Specified by:

commit in interface Transactional

rollback

public void rollback()

Description copied from interface: Transactional

The TransactionManager.rollback method rolls back the transaction associated with the current thread. After the rollback method completes, the thread is associated with no transaction.

Specified by:

rollback in interface Transactional
