Class BlockingOutputStreamAsyncRequestBody

java.lang.Object

software.amazon.awssdk.core.async.BlockingOutputStreamAsyncRequestBody

All Implemented Interfaces:

org.reactivestreams.Publisher<ByteBuffer>, AsyncRequestBody, SdkPublisher<ByteBuffer>

public final class BlockingOutputStreamAsyncRequestBody
extends Object
implements AsyncRequestBody

An implementation of AsyncRequestBody that allows performing a blocking write of an output stream to a downstream service.

The caller is responsible for calling OutputStream.close() on the outputStream() when writing is complete.

Method Details

outputStream

public CancellableOutputStream outputStream()

Return an output stream to which blocking writes can be made to the downstream service.

This method will block the calling thread until the SDK is connected to the service. This means that this request body should usually be passed to the SDK before this method is called.

You can invoke CancellableOutputStream.cancel() to cancel any blocked write calls to the downstream service (and mark the stream as failed).

builder

public static BlockingOutputStreamAsyncRequestBody.Builder builder()

Creates a default builder for BlockingOutputStreamAsyncRequestBody.

contentLength

public Optional<Long> contentLength()

Specified by:

contentLength in interface AsyncRequestBody

Returns:

The content length of the data being produced.

subscribe

public void subscribe(org.reactivestreams.Subscriber<? super ByteBuffer> s)

Specified by:

subscribe in interface org.reactivestreams.Publisher<ByteBuffer>
