Examples with StreamingOutputOperationRequestMarshaller software.amazon.awssdk.services.json.transform.StreamingOutputOperationRequestMarshaller used on opensource projects

Example 1 with StreamingOutputOperationRequestMarshaller

use of software.amazon.awssdk.services.json.transform.StreamingOutputOperationRequestMarshaller in project aws-sdk-java-v2 by aws.

the class DefaultJsonAsyncClient method streamingOutputOperation.

/**
 * Some operation with a streaming output
 *
 * @param streamingOutputOperationRequest
 * @param asyncResponseTransformer
 *        The response transformer for processing the streaming response in a non-blocking manner. See
 *        {@link AsyncResponseTransformer} for details on how this callback should be implemented and for links to
 *        precanned implementations for common scenarios like downloading to a file. The service documentation for
 *        the response content is as follows 'This be a stream'.
 * @return A future to the transformed result of the AsyncResponseTransformer.<br/>
 *         The CompletableFuture returned by this method can be completed exceptionally with the following
 *         exceptions.
 *         <ul>
 *         <li>SdkException Base class for all exceptions that can be thrown by the SDK (both service and client).
 *         Can be used for catch all scenarios.</li>
 *         <li>SdkClientException If any client side error occurs such as an IO related failure, failure to get
 *         credentials, etc.</li>
 *         <li>JsonException Base class for all service exceptions. Unknown exceptions will be thrown as an instance
 *         of this type.</li>
 *         </ul>
