getDefaultConsumer

public Consumer getDefaultConsumer()

Description copied from interface: Channel

Get the current default consumer. @see setDefaultConsumer for rationale.

Specified by:

getDefaultConsumer in interface Channel

Returns:

an interface to the current default consumer.

setDefaultConsumer

public void setDefaultConsumer(Consumer consumer)

Description copied from interface: Channel

Set the current default consumer. Under certain circumstances it is possible for a channel to receive a message delivery which does not match any consumer which is currently set up via basicConsume(). This will occur after the following sequence of events: ctag = basicConsume(queue, consumer); // i.e. with explicit acks // some deliveries take place but are not acked basicCancel(ctag); basicRecover(false); Since requeue is specified to be false in the basicRecover, the spec states that the message must be redelivered to "the original recipient" - i.e. the same channel / consumer-tag. But the consumer is no longer active. In these circumstances, you can register a default consumer to handle such deliveries. If no default consumer is registered an IllegalStateException will be thrown when such a delivery arrives. Most people will not need to use this.

Specified by:

setDefaultConsumer in interface Channel

Parameters:

consumer - the consumer to use, or null indicating "don't use one".

basicQos

public void basicQos(int prefetchSize,
            int prefetchCount,
            boolean global)
              throws java.io.IOException

Description copied from interface: Channel

Request specific "quality of service" settings. These settings impose limits on the amount of data the server will deliver to consumers before requiring acknowledgements. Thus they provide a means of consumer-initiated flow control.

Specified by:

basicQos in interface Channel

Parameters:

prefetchSize - maximum amount of content (measured in octets) that the server will deliver, 0 if unlimited

prefetchCount - maximum number of messages that the server will deliver, 0 if unlimited

global - true if the settings should be applied to the entire channel rather than each consumer

Throws:

java.io.IOException - if an error is encountered

See Also:

AMQP.Basic.Qos
