Method Detail

setReceiver

public abstract SubscriberSettings.Builder setReceiver(com.google.cloud.pubsub.v1.MessageReceiver receiver)

The receiver which handles new messages sent by the Pub/Sub Lite system. Only one downcall from any connected partition will be outstanding at a time, and blocking in this receiver callback will block forward progress.

setSubscriptionPath

public abstract SubscriberSettings.Builder setSubscriptionPath(SubscriptionPath path)

The subscription to use to receive messages.

setPerPartitionFlowControlSettings

public abstract SubscriberSettings.Builder setPerPartitionFlowControlSettings(FlowControlSettings settings)

The per-partition flow control settings. Because these apply per-partition, if you are using them to bound memory usage, keep in mind the number of partitions in the associated topic.

setPartitions

public abstract SubscriberSettings.Builder setPartitions(List<Partition> partition)

The partitions this subscriber should connect to to receive messages. If set, disables auto-assignment.

setTransformer

public abstract SubscriberSettings.Builder setTransformer(MessageTransformer<SequencedMessage,com.google.pubsub.v1.PubsubMessage> transformer)

The MessageTransformer to get PubsubMessages from Pub/Sub Lite wire messages.

setCredentialsProvider

public abstract SubscriberSettings.Builder setCredentialsProvider(com.google.api.gax.core.CredentialsProvider provider)

A provider for credentials.

setSubscriberServiceClientSupplier

public abstract SubscriberSettings.Builder setSubscriberServiceClientSupplier(Supplier<SubscriberServiceClient> supplier)

A supplier for new SubscriberServiceClients. Should return a new client each time. If present, ignores CredentialsProvider.

setCursorServiceClientSupplier

public abstract SubscriberSettings.Builder setCursorServiceClientSupplier(Supplier<CursorServiceClient> supplier)

A supplier for new CursorServiceClients. Should return a new client each time. If present, ignores CredentialsProvider.

setAssignmentServiceClient

public abstract SubscriberSettings.Builder setAssignmentServiceClient(PartitionAssignmentServiceClient client)

A client to connect to the Pub/Sub lite assignment service. If present, ignores CredentialsProvider.

setNackHandler

public abstract SubscriberSettings.Builder setNackHandler(NackHandler nackHandler)

A handler for the action to take when AckReplyConsumer.nack() is called. In Pub/Sub Lite, only a single subscriber for a given subscription is connected to any partition at a time, and there is no other client that may be able to handle messages.
