Method Detail

getInstance

public static ContextTransactionSynchronizationRegistry getInstance()

getTransactionKey

public Object getTransactionKey()

Description copied from interface: TransactionSynchronizationRegistry

An object that has the same equals/hashCode behaviour as the transaction currently associated with the thread

Specified by:

getTransactionKey in interface TransactionSynchronizationRegistry

Returns:

the key or null if there is no current transaction

getTransactionStatus

public int getTransactionStatus()

Description copied from interface: TransactionSynchronizationRegistry

Get the transaction status of the current thread

Specified by:

getTransactionStatus in interface TransactionSynchronizationRegistry

Returns:

the status

getRollbackOnly

public boolean getRollbackOnly()
                        throws IllegalStateException

Description copied from interface: TransactionSynchronizationRegistry

Get the rollback status of the transaction associated with the current thread.

Specified by:

getRollbackOnly in interface TransactionSynchronizationRegistry

Returns:

true when the transaction is rollback only

Throws:

IllegalStateException - if there is no current transaction

setRollbackOnly

public void setRollbackOnly()
                     throws IllegalStateException

Description copied from interface: TransactionSynchronizationRegistry

Set the transaction associated with the current thread to force a rollback

Specified by:

setRollbackOnly in interface TransactionSynchronizationRegistry

Throws:

IllegalStateException - if there is no current transaction

registerInterposedSynchronization

public void registerInterposedSynchronization(Synchronization sync)
                                       throws IllegalStateException

Description copied from interface: TransactionSynchronizationRegistry

Add a transaction synchronization that is invoked "last", i.e. after SessionSynchronizations and directly registered transaction synchronizations.

The beforeCompletion is invoked in the context of the transaction, the afterCompletion in an undefined transaction context. Other context is the same as when the one used to register the synchronization.

Access to "user components" is not allowed, e.g. ejb bean methods.

Access to other resources, e.g. jca, is allowed in the beforeCompletion, but not transactional work is allowed in the afterCompletion. e.g. typically only "close()" is allowed.

Specified by:

registerInterposedSynchronization in interface TransactionSynchronizationRegistry

Parameters:

sync - the synchronization

Throws:

IllegalStateException - if there is no current transaction

getResource

public Object getResource(Object key)
                   throws IllegalStateException

Description copied from interface: TransactionSynchronizationRegistry

Get a transaction local for the current transaction

Specified by:

getResource in interface TransactionSynchronizationRegistry

Parameters:

key - the key to the value

Returns:

the value

Throws:

IllegalStateException - if there is no current transaction

putResource

public void putResource(Object key,
                        Object value)
                 throws IllegalStateException

Description copied from interface: TransactionSynchronizationRegistry

Set a transaction local for the current transaction

Specified by:

putResource in interface TransactionSynchronizationRegistry

Parameters:

key - the key to the value

value - the value

Throws:

IllegalStateException - if there is no current transaction
