Class RabbitMQPublisher

java.lang.Object

io.vertx.rxjava3.rabbitmq.RabbitMQPublisher

public class RabbitMQPublisher
extends Object

A reliable publisher that

• Queues up messages internally until it can successfully call basicPublish.
• Notifies the caller using a robust ID (not delivery tag) when the message is confirmed by rabbit.

This is a layer above the RabbitMQClient that provides a lot of standard implementation when guaranteed at least once delivery is required. If confirmations are not required do not use this publisher as it does have overhead.

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

create

public static RabbitMQPublisher create(Vertx vertx,
                                       RabbitMQClient client,
                                       RabbitMQPublisherOptions options)

Create and return a publisher using the specified client.

Parameters:

vertx - the vertx instance.

client - the RabbitMQClient.

options - options for the publisher.

Returns:

the publisher

start

public Completable start()

Start the rabbitMQ publisher. The RabbitMQClient should have been started before this.

Returns:

rxStart

public Completable rxStart()

Start the rabbitMQ publisher. The RabbitMQClient should have been started before this.

Returns:

stop

public Completable stop()

Stop the rabbitMQ publisher. Calling this is optional, but it gives the opportunity to drain the send queue without losing messages. Future calls to publish will be ignored.

Returns:

rxStop

public Completable rxStop()

Stop the rabbitMQ publisher. Calling this is optional, but it gives the opportunity to drain the send queue without losing messages. Future calls to publish will be ignored.

Returns:

restart

public void restart()

Undo the effects of calling stop() so that publish may be called again. It is harmless to call restart() when stop() has not been called, however if restart() is called whilst stop() is being processed the stop() will never complete.

getConfirmationStream

public ReadStream<RabbitMQPublisherConfirmation> getConfirmationStream()

Get the ReadStream that contains the message IDs for confirmed messages. The message IDs in this ReadStream are taken from the message properties, if these message IDs are not set then this ReadStream will contain nulls and using this publisher will be pointless.

Returns:

the ReadStream that contains the message IDs for confirmed messages.

queueSize

public int queueSize()

Get the number of published, but not sent, messages.

Returns:

the number of published, but not sent, messages.

publish

public Completable publish(String exchange,
                           String routingKey,
