Class PubSubAcknowledgmentCallback

java.lang.Object

com.google.cloud.spring.pubsub.integration.inbound.PubSubAcknowledgmentCallback

All Implemented Interfaces:

org.springframework.integration.acks.AcknowledgmentCallback, org.springframework.integration.acks.SimpleAcknowledgment

public class PubSubAcknowledgmentCallback
extends Object
implements org.springframework.integration.acks.AcknowledgmentCallback

Pub/Sub specific implementation of AcknowledgmentCallback.

AcknowledgmentCallback.isAcknowledged() is implemented for semantic accuracy only, since in Pub/Sub acknowledging a message more than once is not an error.

AcknowledgmentCallback.noAutoAck() is not implemented; the correct way to enable manual acking is through configuring PubSubMessageSource.

Since:

1.2
