Class ByteArrayAsyncResponseTransformer<ResponseT>

java.lang.Object

software.amazon.awssdk.core.internal.async.ByteArrayAsyncResponseTransformer<ResponseT>

Type Parameters:

ResponseT - Pojo response type.

All Implemented Interfaces:

AsyncResponseTransformer<ResponseT,ResponseBytes<ResponseT>>

public final class ByteArrayAsyncResponseTransformer<ResponseT>
extends Object
implements AsyncResponseTransformer<ResponseT,ResponseBytes<ResponseT>>

Implementation of AsyncResponseTransformer that dumps content into a byte array and supports further conversions into types, like strings. This can be created with static methods on AsyncResponseTransformer.

Method Details

prepare

public CompletableFuture<ResponseBytes<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,ResponseBytes<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,ResponseBytes<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,ResponseBytes<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,ResponseBytes<ResponseT>>

Parameters:

throwable - Error that occurred.
