All Superinterfaces:

AutoCloseable, com.rabbitmq.client.Channel, com.rabbitmq.client.ShutdownNotifier

All Known Implementing Classes:

public interface PublisherCallbackChannel
extends com.rabbitmq.client.Channel

Instances of this interface support a single listener being registered for publisher confirms with multiple channels, by adding context to the callbacks.

Method Details

addListener

void addListener(PublisherCallbackChannel.Listener listener)

Adds a PublisherCallbackChannel.Listener.

Parameters:

listener - The Listener.

expire

Collection<PendingConfirm> expire(PublisherCallbackChannel.Listener listener,
 long cutoffTime)

Expire (remove) any PendingConfirms created before cutoffTime for the supplied listener and return them to the caller.

Parameters:

listener - the listener.

cutoffTime - the time before which expired messages were created.

Returns:

the list of expired confirms.

getPendingConfirmsCount

int getPendingConfirmsCount(PublisherCallbackChannel.Listener listener)

Get the PendingConfirms count.

Parameters:

listener - the listener.

Returns:

Count of the pending confirms.

getPendingConfirmsCount

int getPendingConfirmsCount()

Get the total pending confirms count.

Returns:

the count.

Since:

2.1

addPendingConfirm

void addPendingConfirm(PublisherCallbackChannel.Listener listener,
 long seq,
 PendingConfirm pendingConfirm)

Adds a pending confirmation to this channel's map.

Parameters:

listener - The listener.

seq - The key to the map.

pendingConfirm - The PendingConfirm object.

getDelegate

com.rabbitmq.client.Channel getDelegate()

Use this to invoke methods on the underlying rabbit client Channel that are not supported by this implementation.

Returns:

The underlying rabbit client Channel.

Since:

1.4.

setAfterAckCallback

void setAfterAckCallback(Consumer<com.rabbitmq.client.Channel> callback)
