- Method Detail
  - operation
```
@Nullable
public abstract String operation()
```
    The unqualified, case-sensitive semantic message operation name. The currently defined names are "send" and "receive".
    Examples:
    
    Amazon SQS - AmazonSQS.sendMessageBatch() is a "send" operation
    
    JMS - MessageProducer.send() is a "send" operation
    
    Kafka - Consumer.poll() is a "receive" operation
    
    RabbitMQ - Consumer.handleDelivery() is a "receive" operation
    
    Note: There is no constant set of operations, yet. Even when there is a constant set, there may be operations such as "browse" or "purge" which aren't defined. Once implementation matures, a constant file will be defined, with potentially more names.
    Returns:
    
    the messaging operation or null if unreadable.
