public final ServerServiceDefinition bindService()

Returns

Type	Description
io.grpc.ServerServiceDefinition

createTopic(Topic request, StreamObserver<Topic> responseObserver)

public void createTopic(Topic request, StreamObserver<Topic> responseObserver)

Creates the given topic with the given name. See the resource name rules.

Parameters

Name	Description
request	`Topic`
responseObserver	`io.grpc.stub.StreamObserver<Topic>`

deleteTopic(DeleteTopicRequest request, StreamObserver<Empty> responseObserver)

public void deleteTopic(DeleteTopicRequest request, StreamObserver<Empty> responseObserver)

Deletes the topic with the given name. Returns NOT_FOUND if the topic does not exist. After a topic is deleted, a new topic may be created with the same name; this is an entirely new topic with none of the old configuration or subscriptions. Existing subscriptions to this topic are not deleted, but their topic field is set to deleted-topic.

Parameters

Name	Description
request	`DeleteTopicRequest`
responseObserver	`io.grpc.stub.StreamObserver<Empty>`

detachSubscription(DetachSubscriptionRequest request, StreamObserver<DetachSubscriptionResponse> responseObserver)

public void detachSubscription(DetachSubscriptionRequest request, StreamObserver<DetachSubscriptionResponse> responseObserver)

Detaches a subscription from this topic. All messages retained in the subscription are dropped. Subsequent Pull and StreamingPull requests will return FAILED_PRECONDITION. If the subscription is a push subscription, pushes to the endpoint will stop.

Parameters

Name	Description
request	`DetachSubscriptionRequest`
responseObserver	`io.grpc.stub.StreamObserver<DetachSubscriptionResponse>`

getTopic(GetTopicRequest request, StreamObserver<Topic> responseObserver)

public void getTopic(GetTopicRequest request, StreamObserver<Topic> responseObserver)

Gets the configuration of a topic.

Parameters

Name	Description
request	`GetTopicRequest`
responseObserver	`io.grpc.stub.StreamObserver<Topic>`

listTopicSnapshots(ListTopicSnapshotsRequest request, StreamObserver<ListTopicSnapshotsResponse> responseObserver)

public void listTopicSnapshots(ListTopicSnapshotsRequest request, StreamObserver<ListTopicSnapshotsResponse> responseObserver)

Lists the names of the snapshots on this topic. Snapshots are used in Seek 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.

Parameters

Name	Description
request	`ListTopicSnapshotsRequest`
responseObserver	`io.grpc.stub.StreamObserver<ListTopicSnapshotsResponse>`

listTopicSubscriptions(ListTopicSubscriptionsRequest request, StreamObserver<ListTopicSubscriptionsResponse> responseObserver)

Lists the names of the attached subscriptions on this topic.

Parameters

Name	Description
request	`ListTopicSubscriptionsRequest`
responseObserver	`io.grpc.stub.StreamObserver<ListTopicSubscriptionsResponse>`

listTopics(ListTopicsRequest request, StreamObserver<ListTopicsResponse> responseObserver)

public void listTopics(ListTopicsRequest request, StreamObserver<ListTopicsResponse> responseObserver)

Lists matching topics.

Parameters

Name	Description
request	`ListTopicsRequest`
responseObserver	`io.grpc.stub.StreamObserver<ListTopicsResponse>`

publish(PublishRequest request, StreamObserver<PublishResponse> responseObserver)
