public interface SubscriptionOrBuilder extends MessageOrBuilder

Implements

MessageOrBuilder

Methods

containsLabels(String key)

public abstract boolean containsLabels(String key)

See <a href="https://cloud.google.com/pubsub/docs/labels">; Creating and managing labels</a>.

map<string, string> labels = 9;

Parameter

Name	Description
key	`String`

Returns

Type	Description
boolean

getAckDeadlineSeconds()

public abstract int getAckDeadlineSeconds()

The approximate amount of time (on a best-effort basis) Pub/Sub waits for the subscriber to acknowledge receipt before resending the message. In the interval after the message is delivered and before it is acknowledged, it is considered to be <i>outstanding</i>. During that time period, the message will not be redelivered (on a best-effort basis). For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call ModifyAckDeadline with the corresponding ack_id if using non-streaming pull or send the ack_id in a StreamingModifyAckDeadlineRequest if using streaming pull. The minimum custom deadline you can specify is 10 seconds. The maximum custom deadline you can specify is 600 seconds (10 minutes). If this parameter is 0, a default value of 10 seconds is used. For push delivery, this value is also used to set the request timeout for the call to the push endpoint. If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message.

int32 ack_deadline_seconds = 5;

Returns

Type	Description
int	The ackDeadlineSeconds.

getDeadLetterPolicy()

public abstract DeadLetterPolicy getDeadLetterPolicy()

A policy that specifies the conditions for dead lettering messages in this subscription. If dead_letter_policy is not set, dead lettering is disabled. The Cloud Pub/Sub service account associated with this subscriptions's parent project (i.e., service-{project_number}@gcp-sa-pubsub.iam.gserviceaccount.com) must have permission to Acknowledge() messages on this subscription.

.google.pubsub.v1.DeadLetterPolicy dead_letter_policy = 13;

Returns

Type	Description
DeadLetterPolicy	The deadLetterPolicy.

getDeadLetterPolicyOrBuilder()

public abstract DeadLetterPolicyOrBuilder getDeadLetterPolicyOrBuilder()

.google.pubsub.v1.DeadLetterPolicy dead_letter_policy = 13;

Returns

Type	Description
DeadLetterPolicyOrBuilder

getDetached()

public abstract boolean getDetached()

Indicates whether the subscription is detached from its topic. Detached subscriptions don't receive messages from their topic and don't retain any backlog. Pull and StreamingPull requests will return FAILED_PRECONDITION. If the subscription is a push subscription, pushes to the endpoint will not be made.

bool detached = 15;

Returns

Type	Description
boolean	The detached.

getEnableExactlyOnceDelivery()

public abstract boolean getEnableExactlyOnceDelivery()

If true, Pub/Sub provides the following guarantees for the delivery of a message with a given value of message_id on this subscription:

The message sent to a subscriber is guaranteed not to be resent before the message's acknowledgement deadline expires.
An acknowledged message will not be resent to a subscriber. Note that subscribers may still receive multiple copies of a message when enable_exactly_once_delivery is true if the message was published multiple times by a publisher client. These copies are considered distinct by Pub/Sub and have distinct message_id values.

bool enable_exactly_once_delivery = 16;

Returns

Type	Description
boolean	The enableExactlyOnceDelivery.

getEnableMessageOrdering()

public abstract boolean getEnableMessageOrdering()

If true, messages published with the same ordering_key in PubsubMessage will be delivered to the subscribers in the order in which they are received by the Pub/Sub system. Otherwise, they may be delivered in any order.

bool enable_message_ordering = 10;

Returns

Type	Description
boolean	The enableMessageOrdering.

getExpirationPolicy()

public abstract ExpirationPolicy getExpirationPolicy()

A policy that specifies the conditions for this subscription's expiration. A subscription is considered active as long as any connected subscriber is successfully consuming messages from the subscription or is issuing operations on the subscription. If expiration_policy is not set, a default policy with ttl of 31 days will be used. The minimum allowed value for expiration_policy.ttl is 1 day.

.google.pubsub.v1.ExpirationPolicy expiration_policy = 11;

Returns

Type	Description
ExpirationPolicy	The expirationPolicy.

getExpirationPolicyOrBuilder()

public abstract ExpirationPolicyOrBuilder getExpirationPolicyOrBuilder()

ExpirationPolicyOrBuilder

getFilter()

getFilterBytes()

public abstract ByteString getFilterBytes()

string filter = 12;

Returns

Type	Description

getMessageRetentionDuration()

public abstract Duration getMessageRetentionDuration()

How long to retain unacknowledged messages in the subscription's backlog, from the moment a message is published. If retain_acked_messages is true, then this also configures the retention of acknowledged messages, and thus configures how far back in time a Seek can be done. Defaults to 7 days.
