Examples of org.apache.qpid.server.txn.ServerTransaction

org.apache.qpid.server.txn.ServerTransaction
The ServerTransaction interface allows a set enqueue/dequeue operations to be performed against the transaction belonging the underlying TransactionLog object. Typically all ServerTransaction implementations decide if a message should be enlisted into a store transaction by examining the durable property of the queue, and the persistence property of the message. A caller may register a list of post transaction Actions to be performed on commit() (or rollback()).




        // check and deliver if header says body length is zero
        if (currentMessage.allContentReceived())
        {
            ServerTransaction trans = new AutoCommitTransaction(getVirtualHost().getMessageStore());
            final List<? extends BaseQueue> destinationQueues = currentMessage.getDestinationQueues();
            trans.enqueue(currentMessage.getDestinationQueues(), currentMessage, new ServerTransaction.Action() {
                public void postCommit()
                {
                    try
                    {
                        AMQMessage message = new AMQMessage(currentMessage.getStoredMessage());
