Overrides:

errorHandler in class StreamMessageListenerContainer.StreamReadRequestBuilder<K>

Parameters:

errorHandler - must not be null.

Returns:

this StreamMessageListenerContainer.ConsumerStreamReadRequestBuilder.

Configure a Consumer to consume stream messages within a consumer group.

Overrides:

consumer in class StreamMessageListenerContainer.StreamReadRequestBuilder<K>

Parameters:

consumer - must not be null.

Returns:

this StreamMessageListenerContainer.ConsumerStreamReadRequestBuilder.

autoAcknowledge

public StreamMessageListenerContainer.ConsumerStreamReadRequestBuilder<K> autoAcknowledge(boolean autoAck)

Configure auto-acknowledgement for stream message consumption.

Parameters:

autoAck - true (default) to auto-acknowledge received messages or false for external acknowledgement.

Returns:

this StreamMessageListenerContainer.ConsumerStreamReadRequestBuilder.

Since:

2.3

build

public StreamMessageListenerContainer.ConsumerStreamReadRequest<K> build()

Build a new instance of StreamMessageListenerContainer.ConsumerStreamReadRequest.

Overrides:

build in class StreamMessageListenerContainer.StreamReadRequestBuilder<K>

Returns:

a new instance of StreamMessageListenerContainer.ConsumerStreamReadRequest.
