QueueReceiverInterface
interface QueueReceiverInterface implementsReceiverInterface
Some transports may have multiple queues. This interface is used to read from only some queues.
Methods
Acknowledges that the passed message was handled.
Called when handling the message failed and it should not be retried.
Get messages from the specified queue names instead of consuming from all queues.
Details
iterable
get()
Receives some messages.
While this method could return an unlimited number of messages, the intention is that it returns only one, or a "small number" of messages each time. This gives the user more flexibility: they can finish processing the one (or "small number") of messages from this receiver and move on to check other receivers for messages. If this method returns too many messages, it could cause a blocking effect where handling the messages received from one call to get() takes a long time, blocking other receivers from being called.
If applicable, the Envelope should contain a TransportMessageIdStamp.
If a received message cannot be decoded, the message should not be retried again (e.g. if there's a queue, it should be removed) and a MessageDecodingFailedException should be thrown.
