  - 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 But the consumer is no longer active.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 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.
    Note the prefetch count must be between 0 and 65535 (unsigned short in AMQP 0-9-1).
    
    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:
    
    IOException - if an error is encountered
    
    See Also:

    Description copied from interface: Channel
    
    Start a consumer. Calls the consumer's Consumer.handleConsumeOk(java.lang.String) method. Provide access only to basic.deliver and basic.cancel AMQP methods (which is sufficient for most cases). See methods with a Consumer argument to have access to all the application callbacks.

    Parameters:
    
    queue - the name of the queue
    
    autoAck - true if the server should consider messages acknowledged once delivered; false if the server should expect explicit acknowledgements
    
    consumerTag - a client-generated consumer tag to establish context
    
    noLocal - True if the server should not deliver to this consumer messages published on this channel's connection. Note that the RabbitMQ server does not support this flag.
    
    exclusive - true if this is an exclusive consumer
    
    arguments - a set of arguments for the consume
    
    deliverCallback - callback when a message is delivered
    
    cancelCallback - callback when the consumer is cancelled
