    Result of the CancelJournalKinesisStream operation returned by the service.

    Throws:

    InvalidParameterException - One or more parameters in the request aren't valid.

  • shutdown

    void shutdown()

    Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.

  • getCachedResponseMetadata

    ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

    Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

    Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

    Parameters:

    request - The originally executed request.

    Returns:

    The response metadata for the specified request, or null if none is available.
