SubBuilderT	onResponse(Consumer<ResponseT> responseConsumer) Callback to invoke when the initial response is received.
SubBuilderT	publisherTransformer(Function<SdkPublisher<EventT>,SdkPublisher<EventT>> publisherTransformer) Allows for optional transformation of the publisher of events before subscribing.
SubBuilderT	subscriber(Consumer<EventT> eventConsumer) Sets the subscriber to the SdkPublisher of events.
SubBuilderT	subscriber(Supplier<org.reactivestreams.Subscriber<EventT>> eventSubscriberSupplier) Subscriber that will subscribe to the SdkPublisher of events.

Method Detail

onResponse

SubBuilderT onResponse(Consumer<ResponseT> responseConsumer)

Callback to invoke when the initial response is received.

Parameters:

responseConsumer - Callback that will process the initial response.

Returns:

This builder for method chaining.

onError

SubBuilderT onError(Consumer<Throwable> consumer)

Callback to invoke in the event on an error.

Parameters:

consumer - Callback that will process any error that occurs.

Returns:

This builder for method chaining.

onComplete

SubBuilderT onComplete(Runnable runnable)

Action to invoke when the event stream completes.

Parameters:

runnable - Action to run on the completion of the event stream.

Returns:

This builder for method chaining.

subscriber

SubBuilderT subscriber(Supplier<org.reactivestreams.Subscriber<EventT>> eventSubscriberSupplier)

Subscriber that will subscribe to the SdkPublisher of events. Subscriber must be provided.

Parameters:

eventSubscriberSupplier - Supplier for a subscriber that will be subscribed to the publisher of events.

Returns:

This builder for method chaining.

subscriber

SubBuilderT subscriber(Consumer<EventT> eventConsumer)

Sets the subscriber to the SdkPublisher of events. The given consumer will be called for each event received by the publisher. Events are requested sequentially after each event is processed. If you need more control over the backpressure strategy consider using subscriber(Supplier) instead.

Parameters:

eventConsumer - Consumer that will process incoming events.

Returns:

This builder for method chaining.

onEventStream

SubBuilderT onEventStream(Consumer<SdkPublisher<EventT>> onSubscribe)

Callback to invoke when the SdkPublisher is available. This callback must subscribe to the given publisher. This method should not be used with subscriber(Supplier) or any of it's overloads.

Parameters:

onSubscribe - Callback that will subscribe to the SdkPublisher.

Returns:

This builder for method chaining.

publisherTransformer

SubBuilderT publisherTransformer(Function<SdkPublisher<EventT>,SdkPublisher<EventT>> publisherTransformer)

Allows for optional transformation of the publisher of events before subscribing. This transformation must return a SdkPublisher of the same type so methods like SdkPublisher.map(Function) and SdkPublisher.buffer(int) that change the type cannot be used with this method.

Parameters:

publisherTransformer - Function that returns a new SdkPublisher with augmented behavior.

Returns:

This builder for method chaining.
