Interface QueueConnection

  • All Superinterfaces:
    java.lang.AutoCloseable, Connection
    All Known Subinterfaces:
    XAQueueConnection


    public interface QueueConnection
    extends Connection
    A QueueConnection object is an active connection to a point-to-point JMS provider. A client uses a QueueConnection object to create one or more QueueSession objects for producing and consuming messages.

    A QueueConnection can be used to create a QueueSession, from which specialized queue-related objects can be created. A more general, and recommended, approach is to use the Connection object.

    The QueueConnection object should be used to support existing code that has already used it.

    A QueueConnection cannot be used to create objects specific to the publish/subscribe domain. The createDurableConnectionConsumer method inherits from Connection, but must throw an IllegalStateException if used from QueueConnection.

    Since:
    JMS 1.0

      • createQueueSession

        QueueSession createQueueSession(boolean transacted,
                                        int acknowledgeMode)
                                 throws JMSException
        Creates a QueueSession object.
        Parameters:
        transacted - indicates whether the session is transacted
        acknowledgeMode - indicates whether the consumer or the client will acknowledge any messages it receives; ignored if the session is transacted. Legal values are Session.AUTO_ACKNOWLEDGE, Session.CLIENT_ACKNOWLEDGE, and Session.DUPS_OK_ACKNOWLEDGE.
        Returns:
        a newly created queue session
        Throws:
        JMSException - if the QueueConnection object fails to create a session due to some internal error or lack of support for the specific transaction and acknowledgement mode.

      • createConnectionConsumer

        ConnectionConsumer createConnectionConsumer(Queue queue,
                                                    java.lang.String messageSelector,
                                                    ServerSessionPool sessionPool,
                                                    int maxMessages)
                                             throws JMSException
        Creates a connection consumer for this connection (optional operation). This is an expert facility not used by regular JMS clients.
        Parameters:
        queue - the queue to access
        messageSelector - only messages with properties matching the message selector expression are delivered. A value of null or an empty string indicates that there is no message selector for the message consumer.
        sessionPool - the server session pool to associate with this connection consumer
        maxMessages - the maximum number of messages that can be assigned to a server session at one time
        Returns:
        the connection consumer
        Throws:
        JMSException - if the QueueConnection object fails to create a connection consumer due to some internal error or invalid arguments for sessionPool and messageSelector.
        InvalidDestinationException - if an invalid queue is specified.
        InvalidSelectorException - if the message selector is invalid.
