Method Detail

commit

public void commit(ITransactionStatus pStatus)

Description copied from interface: ITransactionManager

Commit the given transaction, with regard to its status. If the transaction has been marked rollback-only programmatically, perform a rollback.

If the transaction wasn't a new one, omit the commit for proper participation in the surrounding transaction. If a previous transaction has been suspended to be able to create a new one, resume the previous transaction after committing the new one.

Note that when the commit call completes, no matter if normally or throwing an exception, the transaction must be fully completed and cleaned up. No rollback call should be expected in such a case. If this method throws an exception other than a TransactionException, then some before-commit error caused the commit attempt to fail. For example, an O/R Mapping tool might have tried to flush changes to the database right before commit, with the resulting DataAccessException causing the transaction to fail. The original exception will be propagated to the caller of this commit method in such a case.

Specified by:

commit in interface ITransactionManager

Parameters:

pStatus - object returned by the getTransaction method

rollback

public void rollback(ITransactionStatus pStatus)

Description copied from interface: ITransactionManager

Perform a rollback of the given transaction.

If the transaction wasn't a new one, just set it rollback-only for proper participation in the surrounding transaction. If a previous transaction has been suspended to be able to create a new one, resume the previous transaction after rolling back the new one.

Do not call rollback on a transaction if commit threw an exception. The transaction will already have been completed and cleaned up when commit returns, even in case of a commit exception. Consequently, a rollback call after commit failure will lead to an IllegalTransactionStateException.

Specified by:

rollback in interface ITransactionManager

Parameters:

pStatus - object returned by the getTransaction method

getTransaction

public ITransactionStatus getTransaction(ITransactionDefinition pDefinition)

Description copied from interface: ITransactionManager

Obtains the currently active transaction or create a new one according to the given transaction definition (containing a propagation behavior).

If the given definition is null, then a default definition (with default propagation and isolation) will be used.

Note that parameters like isolation level or timeout will only be applied to new transactions, and thus be ignored when participating in active ones.

Specified by:

getTransaction in interface ITransactionManager

Parameters:

pDefinition - ITransactionDefinition instance (can be null for defaults), describing propagation behavior, name, etc

Returns:

transaction status object representing the new or current transaction
