Method Detail

begin

public void begin()

Description copied from interface: Transaction

Starts a transaction boundary for the current channel operation. If a transaction is already in progress, this method will join that transaction using reference counting.

Note: For every invocation of this method there must be a corresponding invocation of Transaction.close() method. Failure to ensure this can lead to dangling transactions and unpredictable results.

Specified by:

begin in interface Transaction

commit

public void commit()

Description copied from interface: Transaction

Indicates that the transaction can be successfully committed. It is required that a transaction be in progress when this method is invoked.

Specified by:

Description copied from interface: Transaction

Indicates that the transaction can must be aborted. It is required that a transaction be in progress when this method is invoked.

Specified by:

rollback in interface Transaction

close

public void close()

Description copied from interface: Transaction

Ends a transaction boundary for the current channel operation. If a transaction is already in progress, this method will join that transaction using reference counting. The transaction is completed only if there are no more references left for this transaction.

Note: For every invocation of this method there must be a corresponding invocation of Transaction.begin() method. Failure to ensure this can lead to dangling transactions and unpredictable results.

Specified by:

close in interface Transaction
