Method Details

prepare

public CompletableFuture<ResponseInputStream<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 extends SdkResponse,ResponseInputStream<ResponseT extends SdkResponse>>

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 extends SdkResponse,ResponseInputStream<ResponseT extends SdkResponse>>

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 extends SdkResponse,ResponseInputStream<ResponseT extends SdkResponse>>

Parameters:

publisher - The publisher.

exceptionOccurred

public void exceptionOccurred(Throwable error)

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 extends SdkResponse,ResponseInputStream<ResponseT extends SdkResponse>>

Parameters:

error - Error that occurred.
