Class AsyncInputStreamPublisher

java.lang.Object

org.mule.extension.s3.internal.connection.publisher.InputStreamPublisher

org.mule.extension.s3.internal.connection.publisher.AsyncInputStreamPublisher

All Implemented Interfaces:

org.reactivestreams.Publisher<ByteBuffer>

public class AsyncInputStreamPublisher
extends InputStreamPublisher

Provides a ByteBuffer publisher backed by an existing input stream. The buffer chunks are read and pushed into the subscriber asynchronously on a separate thread, this allows you to use this Publisher with blocking streams, like the TimedPipedInputStream that is provided by the Mule HTTP Service in case of chunked responses. This publisher should only have a single subscriber as we cannot guarantee that the stream is resettable.
