Class CrtResponseFileResponseTransformer<ResponseT>

java.lang.Object

software.amazon.awssdk.services.s3.internal.crt.CrtResponseFileResponseTransformer<ResponseT>

Type Parameters:

ResponseT - Pojo response type.

All Implemented Interfaces:

AsyncResponseTransformer<ResponseT,ResponseT>

public final class CrtResponseFileResponseTransformer<ResponseT>
extends Object
implements AsyncResponseTransformer<ResponseT,ResponseT>

When the CRT Response File option is used in a request, the body is streamed directly to the file. The S3CrtResponseHandlerAdapter in this case will never receive a response body but will call onStream when the request is complete with a publisher that will complete immediately. This transformer is effectively a no-op transformer that waits for the stream to complete and then completes the future with the response.

Method Details

prepare

public CompletableFuture<ResponseT> prepare()

Description copied from interface: AsyncResponseTransformer

Initial call to enable any setup required before the response is handled.

Note that this will be called for each request attempt, up to the number of retries allowed by the configured RetryPolicy.

This method is guaranteed to be called before the request is executed, and before AsyncResponseTransformer.onResponse(Object) is signaled.

Specified by:

prepare in interface AsyncResponseTransformer<ResponseT,ResponseT>

Returns:

The future holding the transformed response.

onResponse

public void onResponse(ResponseT response)

Description copied from interface: AsyncResponseTransformer

Called when the unmarshalled response object is ready.

Specified by:

onResponse in interface AsyncResponseTransformer<ResponseT,ResponseT>

Parameters:

response - The unmarshalled response.

onStream

public void onStream(SdkPublisher<ByteBuffer> publisher)

Description copied from interface: AsyncResponseTransformer

Called when the response stream is ready.

Specified by:

onStream in interface AsyncResponseTransformer<ResponseT,ResponseT>

Parameters:

publisher - The publisher.

exceptionOccurred

public void exceptionOccurred(Throwable throwable)

Description copied from interface: AsyncResponseTransformer

Called when an error is encountered while making the request or receiving the response. Implementations should free up any resources in this method. This method may be called multiple times during the lifecycle of a request if automatic retries are enabled.

Specified by:

exceptionOccurred in interface AsyncResponseTransformer<ResponseT,ResponseT>

Parameters:

throwable - Error that occurred.
