package amqp-client-async

This method tells the client that the requested QoS levels could be handled by the server. The requested QoS applies to all active consumers until a new QoS is defined.

This method requests a specific quality of service. The QoS can be specified for the current channel or for all channels on the connection. The particular properties and semantics of a qos method always depend on the content class semantics. Though the qos method could in principle apply to both peers, it is currently meaningful only for the server.

The server provides the client with a consumer tag, which is used by the client for methods called on the consumer at a later stage.

This method asks the server to start a "consumer", which is a transient request for messages from a specific queue. Consumers last as long as the channel they were declared on, or until the client cancels them.

This method confirms that the cancellation was completed.

This method cancels a consumer. This does not affect already delivered messages, but it does mean the server will not send any more messages for that consumer. The client may receive an arbitrary number of messages in between sending the cancel method and receiving the cancel-ok reply.

This method publishes a message to a specific exchange. The message will be routed to queues as defined by the exchange configuration and distributed to any active consumers when the transaction, if any, is committed.

This method returns an undeliverable message that was published with the "immediate" flag set, or an unroutable message published with the "mandatory" flag set. The reply code and text provide information about the reason that the message was undeliverable.

This method delivers a message to the client, via a consumer. In the asynchronous message delivery model, the client starts a consumer using the Consume method, then the server responds with Deliver methods as and when messages arrive for that consumer.

This method delivers a message to the client following a get method. A message delivered by 'get-ok' must be acknowledged unless the no-ack option was set in the get method.

This method tells the client that the queue has no messages available for the client.

This method provides a direct access to the messages in a queue using a synchronous dialogue that is designed for specific types of application where synchronous functionality is more important than performance.

When sent by the client, this method acknowledges one or more messages delivered via the Deliver or Get-Ok methods.

This method allows a client to reject a message. It can be used to interrupt and cancel large incoming messages, or return untreatable messages to their original queue.

This method asks the server to redeliver all unacknowledged messages on a specified channel. Zero or more messages may be redelivered. This method is deprecated in favour of the synchronous Recover/Recover-Ok.

This method asks the server to redeliver all unacknowledged messages on a specified channel. Zero or more messages may be redelivered. This method replaces the asynchronous Recover.

This method acknowledges a Basic.Recover method.

This method allows a client to reject one or more incoming messages. It can be used to interrupt and cancel large incoming messages, or return untreatable messages to their original queue.
