Package io.atleon.rabbitmq

Class AloRabbitMQSender<T>

java.lang.Object

io.atleon.rabbitmq.AloRabbitMQSender<T>

Type Parameters:

T - outbound message body type (to be serialized)

All Implemented Interfaces:

Closeable, AutoCloseable

public class AloRabbitMQSender<T>
extends Object
implements Closeable

A reactive RabbitMQ sender with at-least-once semantics for producing messages to exchanges in a RabbitMQ cluster

At most one instance of a Sender is kept and can be closed upon invoking close(). However, if after closing, more sent Publishers are subscribed to, a new Sender instance will be created and cached.

Method Detail

from

public static <T> AloRabbitMQSender<T> from(RabbitMQConfigSource configSource)

Creates a new AloRabbitMQSender from the provided RabbitMQConfigSource

Type Parameters:

T - The type of messages bodies sent by this sender

Parameters:

configSource - The reactive source of RabbitMQConfig

Returns:

A new AloRabbitMQSender

sendBodies

public Function<org.reactivestreams.Publisher<T>,Flux<RabbitMQSenderResult<T>>> sendBodies(RabbitMQMessageCreator<T> messageCreator)

Creates a Function that can be used to transform a Publisher of RabbitMQ message bodies to a Publisher of the results of sending each message body. See sendBodies(Publisher, RabbitMQMessageCreator) for further information.

Parameters:

messageCreator - A factory that creates RabbitMQMessages from message bodies

Returns:

A Function useful for Publisher transformations

sendBodies

public Flux<RabbitMQSenderResult<T>> sendBodies(org.reactivestreams.Publisher<T> bodies,
                                                RabbitMQMessageCreator<T> messageCreator)

Sends a sequence of message bodies to be populated in RabbitMQMessages. The destination exchange and routing key (if necessary) must be populated by the provided RabbitMQMessageCreator.

The output of each sent message body is a RabbitMQSenderResult containing the sent value.

Parameters:

bodies - A Publisher of RabbitMQ message bodies

messageCreator - A factory that creates RabbitMQMessages from message bodies

Returns:

a Publisher of the results of each sent message

sendMessage

public Mono<RabbitMQSenderResult<RabbitMQMessage<T>>> sendMessage(RabbitMQMessage<T> message)

Send a single RabbitMQMessage

Parameters:

message - A message to send

Returns:

A Publisher of the result of sending the message

sendMessages

public Flux<RabbitMQSenderResult<RabbitMQMessage<T>>> sendMessages(org.reactivestreams.Publisher<RabbitMQMessage<T>> messages)

Sends a sequence of RabbitMQMessages

The output of each sent message is a RabbitMQSenderResult containing the sent message.

Parameters:

messages - A Publisher of messages to send

Returns:

A Publisher of items referencing the result of each sent message

sendAloBodies

public Function<org.reactivestreams.Publisher<io.atleon.core.Alo<T>>,io.atleon.core.AloFlux<RabbitMQSenderResult<T>>> sendAloBodies(RabbitMQMessageCreator<T> messageCreator)

Creates a Function that can be used to transform a Publisher of Alo items referencing RabbitMQ message bodies to a Publisher of Alo items referencing the result of sending each message body. See sendAloBodies(Publisher, RabbitMQMessageCreator) for further information.

Parameters:

messageCreator - A factory that creates RabbitMQMessages from message bodies

Returns:

A Function useful for Publisher transformations

sendAloBodies

public io.atleon.core.AloFlux<RabbitMQSenderResult<T>> sendAloBodies(org.reactivestreams.Publisher<io.atleon.core.Alo<T>> aloBodies,
                                                                     RabbitMQMessageCreator<T> messageCreator)

Sends a sequence of Alo items referencing message bodies to be populated in RabbitMQMessages. The destination exchange and routing key (if necessary) must be populated by the provided RabbitMQMessageCreator

The output of each sent message body is a RabbitMQSenderResult containing the sent value. Each emitted item is an Alo item referencing a RabbitMQSenderResult and must be acknowledged or nacknowledged such that its processing can be marked complete at the origin of the message.

Parameters:

aloBodies - A Publisher of Alo items referencing RabbitMQ message bodies

messageCreator - A factory that creates RabbitMQMessages from message bodies

Returns:

a Publisher of Alo items referencing the result of each sent message

sendAloMessages

public io.atleon.core.AloFlux<RabbitMQSenderResult<RabbitMQMessage<T>>> sendAloMessages(org.reactivestreams.Publisher<io.atleon.core.Alo<RabbitMQMessage<T>>> aloMessages)

Sends a sequence of Alo items referencing RabbitMQMessages

The output of each sent message is a RabbitMQSenderResult containing the sent message. Each emitted item is an Alo item referencing a RabbitMQSenderResult and must be acknowledged or nacknowledged such that its processing can be marked complete at the origin of the message.

Parameters:

aloMessages - A Publisher of Alo items referencing messages to send

Returns:

A Publisher of Alo items referencing the result of each sent message

close

public void close(Object reason)

Closes this sender and logs the provided reason.

Parameters:

reason - The reason this sender is being closed

close

public void close()

Specified by:

close in interface AutoCloseable
