Method Detail

headersReceived

void headersReceived(SdkHttpResponse response)

Called when the initial response with headers is received.

Parameters:

response - the SdkHttpResponse

onStream

void onStream(org.reactivestreams.Publisher<ByteBuffer> publisher)

Called when the HTTP client is ready to start sending data to the response handler. Implementations must subscribe to the Publisher and request data via a Subscription as they can handle it.

If at any time the subscriber wishes to stop receiving data, it may call Subscription.cancel(). This will be treated as a failure of the response and the exceptionOccurred(Throwable) callback will be invoked.

exceptionOccurred

void exceptionOccurred(Throwable throwable)

Called when an exception occurs during the request/response. This is a terminal method call, no other method invocations should be expected on the SdkHttpResponseHandler after this point.

Parameters:

throwable - the exception that occurred.

complete

T complete()

Called when all parts of the response have been received. This is a terminal method call, no other method invocations should be expected on the SdkHttpResponseHandler after this point.

Returns:

Transformed result.
