      • createSession

        public Session createSession​(boolean transacted,
                             int acknowledgeMode)
                      throws JMSException
        Creates a Session object.
        Specified by:
        createSession in interface Connection
        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 session
        Throws:
        JMSException - if the Connection object fails to create a session due to some internal error or lack of support for the specific transaction and acknowledgement mode.
        Since:
        1.1

      • getClientID

        public String getClientID()
                   throws JMSException
        Gets the client identifier for this connection.

        This value is specific to the JMS provider. It is either preconfigured by an administrator in a ConnectionFactory object or assigned dynamically by the application by calling the setClientID method.

        Specified by:
        getClientID in interface Connection
        Returns:
        the unique client identifier
        Throws:
        JMSException - if the JMS provider fails to return the client ID for this connection due to some internal error.

      • setClientID

        public void setClientID​(String newClientID)
                 throws JMSException
        Sets the client identifier for this connection.

        The preferred way to assign a JMS client's client identifier is for it to be configured in a client-specific ConnectionFactory object and transparently assigned to the Connection object it creates.

        Alternatively, a client can set a connection's client identifier using a provider-specific value. The facility to set a connection's client identifier explicitly is not a mechanism for overriding the identifier that has been administratively configured. It is provided for the case where no administratively specified identifier exists. If one does exist, an attempt to change it by setting it must throw an IllegalStateException. If a client sets the client identifier explicitly, it must do so immediately after it creates the connection and before any other action on the connection is taken. After this point, setting the client identifier is a programming error that should throw an IllegalStateException.

        The purpose of the client identifier is to associate a connection and its objects with a state maintained on behalf of the client by a provider. The only such state identified by the JMS API is that required to support durable subscriptions.

        If another connection with the same clientID is already running when this method is called, the JMS provider should detect the duplicate ID and throw an InvalidClientIDException.

        Specified by:
        setClientID in interface Connection
        Parameters:
        newClientID - the unique client identifier
        Throws:
        JMSException - if the JMS provider fails to set the client ID for this connection due to some internal error.
        InvalidClientIDException - if the JMS client specifies an invalid or duplicate client ID.
        IllegalStateException - if the JMS client attempts to set a connection's client ID at the wrong time or when it has been administratively configured.

      • setExceptionListener

        public void setExceptionListener​(ExceptionListener listener)
                          throws JMSException
        Sets an exception listener for this connection.

        If a JMS provider detects a serious problem with a connection, it informs the connection's ExceptionListener, if one has been registered. It does this by calling the listener's onException method, passing it a JMSException object describing the problem.

        An exception listener allows a client to be notified of a problem asynchronously. Some connections only consume messages, so they would have no other way to learn their connection has failed.

        A connection serializes execution of its ExceptionListener.

        A JMS provider should attempt to resolve connection problems itself before it notifies the client of them.

        Specified by:
        setExceptionListener in interface Connection
        Parameters:
        listener - the exception listener
        Throws:
        JMSException - if the JMS provider fails to set the exception listener for this connection.

      • getClientInternalExceptionListener

        public ClientInternalExceptionListener getClientInternalExceptionListener()
        Gets the ClientInternalExceptionListener object for this connection. Not every ActiveMQConnectionn has a ClientInternalExceptionListener associated with it.
        Returns:
        the listener or null if no listener is registered with the connection.

      • setClientInternalExceptionListener

        public void setClientInternalExceptionListener​(ClientInternalExceptionListener listener)
        Sets a client internal exception listener for this connection. The connection will notify the listener, if one has been registered, of exceptions thrown by container components (e.g. an EJB container in case of Message Driven Beans) during asynchronous processing of a message. It does this by calling the listener's onException() method passing it a Throwable describing the problem.
        Parameters:
        listener - the exception listener

      • start

        public void start()
           throws JMSException
        Starts (or restarts) a connection's delivery of incoming messages. A call to start on a connection that has already been started is ignored.
        Specified by:
        start in interface Connection
        Throws:
        JMSException - if the JMS provider fails to start message delivery due to some internal error.
        See Also:
        Connection.stop()

      • stop

        public void stop()
          throws JMSException
        Temporarily stops a connection's delivery of incoming messages. Delivery can be restarted using the connection's start method. When the connection is stopped, delivery to all the connection's message consumers is inhibited: synchronous receives block, and messages are not delivered to message listeners.

        This call blocks until receives and/or message listeners in progress have completed.

        Stopping a connection has no effect on its ability to send messages. A call to stop on a connection that has already been stopped is ignored.

        A call to stop must not return until delivery of messages has paused. This means that a client can rely on the fact that none of its message listeners will be called and that all threads of control waiting for receive calls to return will not return with a message until the connection is restarted. The receive timers for a stopped connection continue to advance, so receives may time out while the connection is stopped.

        If message listeners are running when stop is invoked, the stop call must wait until all of them have returned before it may return. While these message listeners are completing, they must have the full services of the connection available to them.

        Specified by:
        stop in interface Connection
        Throws:
        JMSException - if the JMS provider fails to stop message delivery due to some internal error.

        Connection.start()

      • close

        public void close()
           throws JMSException
        Closes the connection.

        Since a provider typically allocates significant resources outside the JVM on behalf of a connection, clients should close these resources when they are not needed. Relying on garbage collection to eventually reclaim these resources may not be timely enough.

        There is no need to close the sessions, producers, and consumers of a closed connection.

        Closing a connection causes all temporary destinations to be deleted.

        When this method is invoked, it should not return until message processing has been shut down in an orderly fashion. This means that all message listeners that may have been running have returned, and that all pending receives have returned. A close terminates all pending message receives on the connection's sessions' consumers. The receives may return with a message or with null, depending on whether there was a message available at the time of the close. If one or more of the connection's sessions' message listeners is processing a message at the time when connection close is invoked, all the facilities of the connection and its sessions must remain available to those listeners until they return control to the JMS provider.

        Closing a connection causes any of its sessions' transactions in progress to be rolled back. In the case where a session's work is coordinated by an external transaction manager, a session's commit and rollback methods are not used and the result of a closed session's work is determined later by the transaction manager. Closing a connection does NOT force an acknowledgment of client-acknowledged sessions.

        Invoking the acknowledge method of a received message from a closed connection's session must throw an IllegalStateException. Closing a closed connection must NOT throw an exception.

        Specified by:
        close in interface Closeable
        Specified by:
        close in interface Connection
        Throws:
        JMSException - if the JMS provider fails to close the connection due to some internal error. For example, a failure to release resources or to close a socket connection can cause this exception to be thrown.

      • setAlwaysSessionAsync

        public void setAlwaysSessionAsync​(boolean alwaysSessionAsync)
        If this flag is not set then a separate thread is not used for dispatching messages for each Session in the Connection. However, a separate thread is always used if there is more than one session, or the session isn't in auto acknowledge or duplicates ok mode. By default this value is set to true and session dispatch happens asynchronously.

      • isOptimizeAcknowledge

        public boolean isOptimizeAcknowledge()
        Returns:
        Returns the optimizeAcknowledge.

      • setOptimizeAcknowledge

      • setWarnAboutUnstartedConnectionTimeout

        public void setWarnAboutUnstartedConnectionTimeout​(long warnAboutUnstartedConnectionTimeout)
        Enables the timeout from a connection creation to when a warning is generated if the connection is not properly started via start() and a message is received by a consumer. It is a very common gotcha to forget to start the connection so this option makes the default case to create a warning if the user forgets. To disable the warning just set the value to < 0 (say -1).

      • getSendTimeout

        public int getSendTimeout()
        Returns:

      • onClientInternalException

        public void onClientInternalException​(Throwable error)
        Handles async client internal exceptions. A client internal exception is usually one that has been thrown by a container runtime component during asynchronous processing of a message that does not affect the connection itself. This method notifies the ClientInternalExceptionListener by invoking its onException method, if one has been registered with this connection.
        Parameters:
        error - the exception that the problem

      • onAsyncException

        public void onAsyncException​(Throwable error)

        error -

      • setUseCompression

        public void setUseCompression​(boolean useCompression)
        Enables the use of compression of the message bodies

      • setDispatchAsync

        public void setDispatchAsync​(boolean asyncDispatch)
        Enables or disables the default setting of whether or not consumers have their messages dispatched synchronously or asynchronously by the broker. For non-durable topics for example we typically dispatch synchronously by default to minimize context switches which boost performance. However sometimes its better to go slower to ensure that a single blocked consumer socket does not block delivery to other consumers.
        Parameters:
        asyncDispatch - If true then consumers created on this connection will default to having their messages dispatched asynchronously. The default value is true.

      • setObjectMessageSerializationDefered

        public void setObjectMessageSerializationDefered​(boolean objectMessageSerializationDefered)
        When an object is set on an ObjectMessage, the JMS spec requires the object to be serialized by that set method. Enabling this flag causes the object to not get serialized. The object may subsequently get serialized if the message needs to be sent over a socket or stored to disk.

      • unsubscribe

        public void unsubscribe​(String name)
                 throws InvalidDestinationException,
                        JMSException
        Unsubscribes a durable subscription that has been created by a client.

        This method deletes the state being maintained on behalf of the subscriber by its provider.

        It is erroneous for a client to delete a durable subscription while there is an active MessageConsumer or TopicSubscriber for the subscription, or while a consumed message is part of a pending transaction or has not been acknowledged in the session.

        Parameters:
        name - the name used to identify this subscription
        Throws:
        JMSException - if the session fails to unsubscribe to the durable subscription due to some internal error.
        InvalidDestinationException - if an invalid subscription name is specified.
        Since:
        1.1

      • setCopyMessageOnSend

        public void setCopyMessageOnSend​(boolean copyMessageOnSend)
        Should a JMS message be copied to a new JMS Message object as part of the send() method in JMS. This is enabled by default to be compliant with the JMS specification. You can disable it if you do not mutate JMS messages after they are sent for a performance boost

      • setCheckForDuplicates

        public void setCheckForDuplicates​(boolean checkForDuplicates)
        Parameters:
        checkForDuplicates - the checkForDuplicates to set

      • cleanUpTempDestinations

        public void cleanUpTempDestinations()
        Removes any TempDestinations that this connection has cached, ignoring any exceptions generated because the destination is in use as they should not be removed. Used from a pooled connection, b/c it will not be explicitly closed.

      • setRedeliveryPolicyMap

        public void setRedeliveryPolicyMap​(RedeliveryPolicyMap redeliveryPolicyMap)
        Sets the Connection wide RedeliveryPolicyMap for handling messages that are being rolled back.

        Returns:
        the redeliveryPolicyMap

      • getOptimizedAckScheduledAckInterval

        public long getOptimizedAckScheduledAckInterval()
        Gets the configured time interval that is used to force all MessageConsumers that have optimizedAcknowledge enabled to send an ack for any outstanding Message Acks. By default this value is set to zero meaning that the consumers will not do any background Message acknowledgment.
        Returns:
        the scheduledOptimizedAckInterval

      • setOptimizedAckScheduledAckInterval

        public void setOptimizedAckScheduledAckInterval​(long optimizedAckScheduledAckInterval)
        Sets the amount of time between scheduled sends of any outstanding Message Acks for consumers that have been configured with optimizeAcknowledge enabled.

      • isConsumerExpiryCheckEnabled

        public boolean isConsumerExpiryCheckEnabled()
        Returns:
        true if MessageConsumer instance will check for expired messages before dispatch.

      • setConsumerExpiryCheckEnabled

        public void setConsumerExpiryCheckEnabled​(boolean consumerExpiryCheckEnabled)
        Controls whether message expiration checking is done in each MessageConsumer prior to dispatching a message. Disabling this check can lead to consumption of expired messages.
        Parameters:
        consumerExpiryCheckEnabled - controls whether expiration checking is done prior to dispatch.
