Interface PublisherGrpc.AsyncService (1.130.0)

public static interface PublisherGrpc.AsyncService

The service that an application uses to manipulate topics, and to send messages to a topic.

Methods

createTopic(Topic request, StreamObserver<Topic> responseObserver)

public default 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 default 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 default 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)

listTopicSnapshots(ListTopicSnapshotsRequest request, StreamObserver<ListTopicSnapshotsResponse> responseObserver)

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