Method Detail

sendCommand

public SendCommandResult sendCommand(SendCommandRequest request)

Description copied from interface: AmazonQLDBSession

Sends a command to an Amazon QLDB ledger.

Instead of interacting directly with this API, we recommend using the QLDB driver or the QLDB shell to execute data transactions on a ledger.

• If you are working with an AWS SDK, use the QLDB driver. The driver provides a high-level abstraction layer above this QLDB Session data plane and manages SendCommand API calls for you. For information and a list of supported programming languages, see Getting started with the driver in the Amazon QLDB Developer Guide.

• If you are working with the AWS Command Line Interface (AWS CLI), use the QLDB shell. The shell is a command line interface that uses the QLDB driver to interact with a ledger. For information, see Accessing Amazon QLDB using the QLDB shell.

Specified by:

sendCommand in interface AmazonQLDBSession

Returns:

Result of the SendCommand operation returned by the service.

shutdown

public void shutdown()

Description copied from interface: AmazonQLDBSession

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.

Specified by:

shutdown in interface AmazonQLDBSession

getCachedResponseMetadata

public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Description copied from interface: AmazonQLDBSession

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.

Specified by:

getCachedResponseMetadata in interface AmazonQLDBSession

Parameters:

request - The originally executed request.

Returns:

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