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

org.apache.qpid.server.txn.LocalTransaction
A concrete implementation of ServerTransaction where enqueue/dequeue operations share a single long-lived transaction. The caller is responsible for invoking commit() (or rollback()) as necessary.

        getVirtualHost().getSecurityManager().authorisePurge(this);


        QueueEntryIterator queueListIterator = _entries.iterator();
        long count = 0;

        while (queueListIterator.advance())
        {
            QueueEntry node = queueListIterator.getNode();
            if (node.acquire())
            {
