Enclosing class:

SubscriberGrpc

public static final class SubscriberGrpc.SubscriberFutureStub
extends AbstractFutureStub<SubscriberGrpc.SubscriberFutureStub>

A stub to allow clients to do ListenableFuture-style rpc calls to service Subscriber.

 The service that an application uses to manipulate subscriptions and to
 consume messages from a subscription via the `Pull` method or by
 establishing a bi-directional stream using the `StreamingPull` method.

createSubscription

public com.google.common.util.concurrent.ListenableFuture<Subscription> createSubscription(Subscription request)

 Creates a subscription to a given topic. See the [resource name rules]
 (https://cloud.google.com/pubsub/docs/admin#resource_names).
 If the subscription already exists, returns `ALREADY_EXISTS`.
 If the corresponding topic doesn't exist, returns `NOT_FOUND`.
 If the name is not provided in the request, the server will assign a random
 name for this subscription on the same project as the topic, conforming
 to the [resource name format]
 (https://cloud.google.com/pubsub/docs/admin#resource_names). The generated
 name is populated in the returned Subscription object. Note that for REST
 API requests, you must specify a name in the request.
 

getSubscription

public com.google.common.util.concurrent.ListenableFuture<Subscription> getSubscription(GetSubscriptionRequest request)

 Gets the configuration details of a subscription.
 

updateSubscription

public com.google.common.util.concurrent.ListenableFuture<Subscription> updateSubscription(UpdateSubscriptionRequest request)

 Updates an existing subscription. Note that certain properties of a
 subscription, such as its topic, are not modifiable.
 

listSubscriptions

public com.google.common.util.concurrent.ListenableFuture<ListSubscriptionsResponse> listSubscriptions(ListSubscriptionsRequest request)

 Lists matching subscriptions.
 

deleteSubscription

public com.google.common.util.concurrent.ListenableFuture<com.google.protobuf.Empty> deleteSubscription(DeleteSubscriptionRequest request)

 Deletes an existing subscription. All messages retained in the subscription
 are immediately dropped. Calls to `Pull` after deletion will return
 `NOT_FOUND`. After a subscription is deleted, a new one may be created with
 the same name, but the new one has no association with the old
 subscription or its topic unless the same topic is specified.
 

modifyAckDeadline

public com.google.common.util.concurrent.ListenableFuture<com.google.protobuf.Empty> modifyAckDeadline(ModifyAckDeadlineRequest request)

 Modifies the ack deadline for a specific message. This method is useful
 to indicate that more time is needed to process a message by the
 subscriber, or to make the message available for redelivery if the
 processing was interrupted. Note that this does not modify the
 subscription-level `ackDeadlineSeconds` used for subsequent messages.
 

acknowledge

public com.google.common.util.concurrent.ListenableFuture<com.google.protobuf.Empty> acknowledge(AcknowledgeRequest request)

 Acknowledges the messages associated with the `ack_ids` in the
 `AcknowledgeRequest`. The Pub/Sub system can remove the relevant messages
 from the subscription.
 Acknowledging a message whose ack deadline has expired may succeed,
 but such a message may be redelivered later. Acknowledging a message more
 than once will not result in an error.
 

pull

public com.google.common.util.concurrent.ListenableFuture<PullResponse> pull(PullRequest request)

 Pulls messages from the server.
 

modifyPushConfig

public com.google.common.util.concurrent.ListenableFuture<com.google.protobuf.Empty> modifyPushConfig(ModifyPushConfigRequest request)

 Modifies the `PushConfig` for a specified subscription.
 This may be used to change a push subscription to a pull one (signified by
 an empty `PushConfig`) or vice versa, or change the endpoint URL and other
 attributes of a push subscription. Messages will accumulate for delivery
 continuously through the call regardless of changes to the `PushConfig`.
 

getSnapshot

public com.google.common.util.concurrent.ListenableFuture<Snapshot> getSnapshot(GetSnapshotRequest request)

 Gets the configuration details of a snapshot. Snapshots are used in
 [Seek](https://cloud.google.com/pubsub/docs/replay-overview) operations,
 which allow you to manage message acknowledgments in bulk. That is, you can
 set the acknowledgment state of messages in an existing subscription to the
 state captured by a snapshot.
 

listSnapshots

public com.google.common.util.concurrent.ListenableFuture<ListSnapshotsResponse> listSnapshots(ListSnapshotsRequest request)

 Lists the existing snapshots. Snapshots are used in [Seek](
 https://cloud.google.com/pubsub/docs/replay-overview) operations, which
 allow you to manage message acknowledgments in bulk. That is, you can set
 the acknowledgment state of messages in an existing subscription to the
 state captured by a snapshot.
 

createSnapshot

public com.google.common.util.concurrent.ListenableFuture<Snapshot> createSnapshot(CreateSnapshotRequest request)

 Creates a snapshot from the requested subscription. Snapshots are used in
 [Seek](https://cloud.google.com/pubsub/docs/replay-overview) operations,
 which allow you to manage message acknowledgments in bulk. That is, you can
 set the acknowledgment state of messages in an existing subscription to the
 state captured by a snapshot.
 If the snapshot already exists, returns `ALREADY_EXISTS`.
 If the requested subscription doesn't exist, returns `NOT_FOUND`.
 If the backlog in the subscription is too old -- and the resulting snapshot
 would expire in less than 1 hour -- then `FAILED_PRECONDITION` is returned.
 See also the `Snapshot.expire_time` field. If the name is not provided in
 the request, the server will assign a random
 name for this snapshot on the same project as the subscription, conforming
 to the [resource name format]
 (https://cloud.google.com/pubsub/docs/admin#resource_names). The
 generated name is populated in the returned Snapshot object. Note that for
 REST API requests, you must specify a name in the request.
 

updateSnapshot

public com.google.common.util.concurrent.ListenableFuture<Snapshot> updateSnapshot(UpdateSnapshotRequest request)

 Updates an existing snapshot. Snapshots are used in
 [Seek](https://cloud.google.com/pubsub/docs/replay-overview) operations,
 which allow you to manage message acknowledgments in bulk. That is, you can
 set the acknowledgment state of messages in an existing subscription to the
 state captured by a snapshot.
 

deleteSnapshot

public com.google.common.util.concurrent.ListenableFuture<com.google.protobuf.Empty> deleteSnapshot(DeleteSnapshotRequest request)

 Removes an existing snapshot. Snapshots are used in [Seek]
 (https://cloud.google.com/pubsub/docs/replay-overview) operations, which
 allow you to manage message acknowledgments in bulk. That is, you can set
 the acknowledgment state of messages in an existing subscription to the
 state captured by a snapshot.
 When the snapshot is deleted, all messages retained in the snapshot
 are immediately dropped. After a snapshot is deleted, a new one may be
 created with the same name, but the new one has no association with the old
 snapshot or its subscription, unless the same subscription is specified.
 

seek

public com.google.common.util.concurrent.ListenableFuture<SeekResponse> seek(SeekRequest request)

 Seeks an existing subscription to a point in time or to a given snapshot,
 whichever is provided in the request. Snapshots are used in [Seek]
 (https://cloud.google.com/pubsub/docs/replay-overview) operations, which
 allow you to manage message acknowledgments in bulk. That is, you can set
 the acknowledgment state of messages in an existing subscription to the
 state captured by a snapshot. Note that both the subscription and the
 snapshot must be on the same topic.
