public sealed class ReceivedMessage : IMessage<ReceivedMessage>, IEquatable<ReceivedMessage>, IDeepCloneable<ReceivedMessage>, IBufferMessage, IMessage
Reference documentation and code samples for the Cloud Pub/Sub v1 API class ReceivedMessage.
A message and its corresponding acknowledgment ID.
Optional. The approximate number of times that Pub/Sub has attempted to
deliver the associated message to a subscriber.
More precisely, this is 1 + (number of NACKs) +
(number of ack_deadline exceeds) for this message.
A NACK is any call to ModifyAckDeadline with a 0 deadline. An ack_deadline
exceeds event is whenever a message is not acknowledged within
ack_deadline. Note that ack_deadline is initially
Subscription.ackDeadlineSeconds, but may get extended automatically by
the client library.
Upon the first delivery of a given message, delivery_attempt will have a
value of 1. The value is calculated at best effort and is approximate.
If a DeadLetterPolicy is not set on the subscription, this will be 0.
