Example 1 with EventStreamOperationResponseHandler

use of software.amazon.awssdk.services.xml.model.EventStreamOperationResponseHandler in project aws-sdk-java-v2 by aws.

the class DefaultXmlAsyncClient method eventStreamOperation.

/**
 * Invokes the EventStreamOperation operation asynchronously.
 *
 * @param eventStreamOperationRequest
 * @return A Java Future containing the result of the EventStreamOperation operation returned by the service.<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>XmlException Base class for all service exceptions. Unknown exceptions will be thrown as an instance
 *         of this type.</li>
 *         </ul>
