Method Detail

close

public void close(AsyncResult request)

Overrides:

close in class AmqpAbstractResource<JmsProducerInfo,org.apache.qpid.proton.engine.Sender>

send

public boolean send(JmsOutboundMessageDispatch envelope,
           AsyncResult request)
             throws IOException,
                    javax.jms.JMSException

Description copied from class: AmqpProducer

Sends the given message

Specified by:

Parameters:

envelope - The envelope that contains the message and it's targeted destination.

request - The AsyncRequest that will be notified on send success or failure.

Returns:

true if the producer had credit to send or false if there was no available credit and the send needed to be deferred.

Throws:

IOException - if an error occurs sending the message

javax.jms.JMSException - if an error occurs while preparing the message for send.

processFlowUpdates

public void processFlowUpdates(AmqpProvider provider)
                        throws IOException

Description copied from interface: AmqpEventSink

Called when the Proton Engine signals an Flow related event has been triggered for the given endpoint.

Specified by:

processFlowUpdates in interface AmqpEventSink

Overrides:

processFlowUpdates in class AmqpAbstractResource<JmsProducerInfo,org.apache.qpid.proton.engine.Sender>

Parameters:

provider - the AmqpProvider instance for easier access to fire events.

Throws:

IOException - if an error occurs while processing the update.

processDeliveryUpdates

public void processDeliveryUpdates(AmqpProvider provider)
                            throws IOException

Description copied from interface: AmqpEventSink

Called when the Proton Engine signals an Delivery related event has been triggered for the given endpoint.

Specified by:

processDeliveryUpdates in interface AmqpEventSink

Overrides:

processDeliveryUpdates in class AmqpAbstractResource<JmsProducerInfo,org.apache.qpid.proton.engine.Sender>

Parameters:

provider - the AmqpProvider instance for easier access to fire events.

Throws:

IOException - if an error occurs while processing the update.

getSession

public AmqpSession getSession()

isAnonymous

public boolean isAnonymous()

Specified by:

isAnonymous in class AmqpProducer

Returns:

true if this is an anonymous producer or false if fixed to a given destination.

setPresettle

public void setPresettle(boolean presettle)

Description copied from class: AmqpProducer

Sets whether the producer will presettle all messages that it sends. Sending presettled reduces the time it takes to send a message but increases the change of message loss should the connection drop during send.

Overrides:

setPresettle in class AmqpProducer

Parameters:

presettle - true if all messages are sent settled.

isPresettle

public boolean isPresettle()

Overrides:

isPresettle in class AmqpProducer

Returns:

true if the producer should presettle all sent messages.

toString

public String toString()

Overrides:

toString in class Object

remotelyClosed

public void remotelyClosed(AmqpProvider provider)

Overrides:

remotelyClosed in class AmqpAbstractResource<JmsProducerInfo,org.apache.qpid.proton.engine.Sender>
