  - bindConsumer
```
Binding<T> bindConsumer(String name,
                        String group,
                        T inboundBindTarget,
                        C consumerProperties)
```
    Bind the target component as a message consumer to the logical entity identified by the name.
    
    Parameters:
    
    name - the logical identity of the message source
    
    group - the consumer group to which this consumer belongs - subscriptions are shared among consumers in the same group (a null or empty String, must be treated as an anonymous group that doesn't share the subscription with any other consumer)
    
    inboundBindTarget - the app interface to be bound as a consumer
    
    consumerProperties - the consumer properties
    
    Returns:
    
    the setup binding
  - bindProducer
```
Binding<T> bindProducer(String name,
                        T outboundBindTarget,
                        P producerProperties)
```
    Bind the target component as a message producer to the logical entity identified by the name.
    
    Parameters:
    
    name - the logical identity of the message target
    
    outboundBindTarget - the app interface to be bound as a producer
    
    producerProperties - the producer properties
