Method Detail

getTransactionManager

public jakarta.transaction.TransactionManager getTransactionManager()
                                                             throws Exception

Description copied from interface: ManagedRuntime

Return the TransactionManager for the managed runtime. This manager is used to register synchronization listeners, to map transactional PersistenceManagers to the current transaction, and possibly to enlist XA resources.

Specified by:

getTransactionManager in interface ManagedRuntime

Throws:

Exception

setConfiguration

public void setConfiguration(Configuration conf)

Specified by:

setConfiguration in interface Configurable

startConfiguration

public void startConfiguration()

Specified by:

startConfiguration in interface Configurable

endConfiguration

public void endConfiguration()

Specified by:

endConfiguration in interface Configurable

setRollbackOnly

public void setRollbackOnly(Throwable cause)
                     throws Exception

Description copied from interface: ManagedRuntime

Sets the rollback only flag on the current transaction. If the TransactionManager is capable of tracking the cause of the rollback-only flag, it will also pass along cause information.

Specified by:

setRollbackOnly in interface ManagedRuntime

Parameters:

cause - the Throwable that caused the transaction to be marked for rollback, or null of none is known

Throws:

Exception

getRollbackCause

public Throwable getRollbackCause()
                           throws Exception

Description copied from interface: ManagedRuntime

Returns the Throwable that caused the current transaction to be marked for rollback, provided that any exists.

Specified by:

getRollbackCause in interface ManagedRuntime

Returns:

the Throwable cause, or null if none

Throws:

Exception

getTransactionKey

public Object getTransactionKey()
                         throws Exception,
                                jakarta.transaction.SystemException

Description copied from class: AbstractManagedRuntime

Returns a transaction key that can be used to associate transactions and Brokers. The default implementation returns the Transaction associated with the current thread's transaction.

Specified by:

getTransactionKey in interface ManagedRuntime

Overrides:

getTransactionKey in class AbstractManagedRuntime

Returns:

the transaction key

Throws:

Exception

jakarta.transaction.SystemException

doNonTransactionalWork

public void doNonTransactionalWork(Runnable runnable)
                            throws jakarta.transaction.NotSupportedException

Delegate nonTransactional work to the appropriate managed runtime. If no managed runtime is found then delegate AbstractManagedRuntime.

Specified by:

doNonTransactionalWork in interface ManagedRuntime

Overrides:

doNonTransactionalWork in class AbstractManagedRuntime

Parameters:

runnable - The runnable wrapper for the work that will be done. The runnable object should be fully initialized with any state needed to execute.

Throws:

jakarta.transaction.NotSupportedException - if the current transaction can not be obtained, or an error occurs when suspending or resuming the transaction.
