  Interface for accessing AmazonSimpleWorkflow. Amazon Simple Workflow Service

  The Amazon Simple Workflow Service API Reference is intended for programmers who need detailed information about the Amazon SWF actions and data types.

  For an broader overview of the Amazon SWF programming model, please go to the Amazon SWF Developer Guide .

  This section provides an overview of Amazon SWF actions.

  Action Categories

  The Amazon SWF actions can be grouped into the following major categories.

  - Actions related to Activities

  - Actions related to Deciders

  - Actions related to Workflow Executions

  - Actions related to Administration

  - Actions related to Visibility

  Actions related to Activities

  The following are actions that are performed by activity workers:

  - PollForActivityTask

  - RespondActivityTaskCompleted

  - RespondActivityTaskFailed

  - RespondActivityTaskCanceled

  - RecordActivityTaskHeartbeat

  Activity workers use the PollForActivityTask to get new activity tasks. After a worker receives an activity task from Amazon SWF, it performs the task and responds using RespondActivityTaskCompleted if successful or RespondActivityTaskFailed if unsuccessful.

  Actions related to Deciders

  The following are actions that are performed by deciders:

  - PollForDecisionTask

  - RespondDecisionTaskCompleted

  Deciders use PollForDecisionTask to get decision tasks. After a decider receives a decision task from Amazon SWF, it examines its workflow execution history and decides what to do next. It calls RespondDecisionTaskCompletedto complete the decision task and provide zero or more next decisions.

  Actions related to Workflow Executions

  The following actions operate on a workflow execution:

  - RequestCancelWorkflowExecution

  - StartWorkflowExecution

  - SignalWorkflowExecution

  - TerminateWorkflowExecution

  Actions related to Administration

  Although you can perform administrative tasks from the Amazon SWF console, you can use the actions in this section to automate functions or build your own administrative tools.

  - DeprecateActivityType

  Workflow Management

  - RegisterWorkflowType

  - DeprecateWorkflowType

  Domain Management

- - ### メソッドの詳細

    - #### setEndpoint

          void setEndpoint(java.lang.String endpoint)
                           throws java.lang.IllegalArgumentException

      Overrides the default endpoint for this client ("https://swf.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.

      Callers can pass in just the endpoint (ex: "swf.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://swf.us-east-1.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's `ClientConfiguration` will be used, which by default is HTTPS.

      For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=3912

      This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

      パラメータ:
        `endpoint` - The endpoint (ex: "swf.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://swf.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
      例外:
        `java.lang.IllegalArgumentException` - If any problems are detected with the specified endpoint.

    - #### setRegion

          void setRegion(Region region)
                         throws java.lang.IllegalArgumentException

      An alternative to `setEndpoint(String)`, sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.

      By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the `ClientConfiguration` supplied at construction.

      This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

      パラメータ:
        `region` - The region this client will communicate with. See `Region.getRegion(com.amazonaws.regions.Regions)` for accessing a given region.
      例外:
        `java.lang.IllegalArgumentException` - If the given region is null, or if this service isn't available in the given region. See `Region.isServiceSupported(String)`
      関連項目:
        `Region.getRegion(com.amazonaws.regions.Regions)`, `Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration)`

    - #### deprecateWorkflowType

          void deprecateWorkflowType(DeprecateWorkflowTypeRequest deprecateWorkflowTypeRequest)
                                     throws AmazonServiceException,
                                            AmazonClientException

      Deprecates the specified workflow type . After a workflow type has been deprecated, you cannot create new executions of that type. Executions that were started before the type was deprecated will continue to run. A deprecated workflow type may still be used when calling visibility actions.

      NOTE: This operation is eventually consistent. The results are best effort and may not exactly reflect recent updates and changes.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - Constrain the following parameters by using a `Condition` element with the appropriate keys.
        - `workflowType.name` : String constraint. The key is `swf:workflowType.name` .
        - `workflowType.version` : String constraint. The key is `swf:workflowType.version` .

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

      パラメータ:
        `deprecateWorkflowTypeRequest` - Container for the necessary parameters to execute the DeprecateWorkflowType service method on AmazonSimpleWorkflow.
      例外:
        `TypeDeprecatedException`
        `OperationNotPermittedException`
        `UnknownResourceException`
        `AmazonClientException` - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
        `AmazonServiceException` - If an error response is returned by AmazonSimpleWorkflow indicating either a problem with the data in the request, or a server side issue.

    - #### deprecateDomain

          void deprecateDomain(DeprecateDomainRequest deprecateDomainRequest)
                               throws AmazonServiceException,
                                      AmazonClientException

      Deprecates the specified domain. After a domain has been deprecated it cannot be used to create new workflow executions or register new types. However, you can still use visibility actions on this domain. Deprecating a domain also deprecates all activity and workflow types registered in the domain. Executions that were started before the domain was deprecated will continue to run.

      NOTE: This operation is eventually consistent. The results are best effort and may not exactly reflect recent updates and changes.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - You cannot use an IAM policy to constrain this action's parameters.

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

      パラメータ:
        `deprecateDomainRequest` - Container for the necessary parameters to execute the DeprecateDomain service method on AmazonSimpleWorkflow.
      例外:
        `DomainDeprecatedException`
        `OperationNotPermittedException`
        `UnknownResourceException`
        `AmazonClientException` - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
        `AmazonServiceException` - If an error response is returned by AmazonSimpleWorkflow indicating either a problem with the data in the request, or a server side issue.

    - #### registerWorkflowType

          void registerWorkflowType(RegisterWorkflowTypeRequest registerWorkflowTypeRequest)
                                    throws AmazonServiceException,
                                           AmazonClientException

      Registers a new workflow type and its configuration settings in the specified domain.

      The retention period for the workflow history is set by the RegisterDomain action.

      IMPORTANT: If the type already exists, then a TypeAlreadyExists fault is returned. You cannot change the configuration settings of a workflow type once it is registered and it must be registered as a new version.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - Constrain the following parameters by using a `Condition` element with the appropriate keys.
        - `defaultTaskList` : String constraint. The key is `swf:defaultTaskList.name` .
        - `name` : String constraint. The key is `swf:name` .
        - `version` : String constraint. The key is `swf:version` .

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

      パラメータ:

        `AmazonServiceException` - If an error response is returned by AmazonSimpleWorkflow indicating either a problem with the data in the request, or a server side issue.

    - #### listWorkflowTypes

          WorkflowTypeInfos listWorkflowTypes(ListWorkflowTypesRequest listWorkflowTypesRequest)
                                              throws AmazonServiceException,
                                                     AmazonClientException

      Returns information about workflow types in the specified domain. The results may be split into multiple pages that can be retrieved by making the call repeatedly.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - You cannot use an IAM policy to constrain this action's parameters.

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

                                     throws AmazonServiceException,
                                            AmazonClientException

      Starts an execution of the workflow type in the specified domain using the provided `workflowId` and input data.

      This action returns the newly started workflow execution.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - Constrain the following parameters by using a `Condition` element with the appropriate keys.
        - `tagList.member.0` : The key is `swf:tagList.member.0` .
        - `tagList.member.1` : The key is `swf:tagList.member.1` .

    - #### signalWorkflowExecution

          void signalWorkflowExecution(SignalWorkflowExecutionRequest signalWorkflowExecutionRequest)
                                       throws AmazonServiceException,
                                              AmazonClientException

      Records a `WorkflowExecutionSignaled` event in the workflow execution history and creates a decision task for the workflow execution identified by the given domain, workflowId and runId. The event is recorded with the specified user defined signalName and input (if provided).

      NOTE: If a runId is not specified, then the WorkflowExecutionSignaled event is recorded in the history of the current open workflow with the matching workflowId in the domain.

      NOTE: If the specified workflow execution is not open, this method fails with UnknownResource.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - You cannot use an IAM policy to constrain this action's parameters.

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

      パラメータ:

      例外:
        `OperationNotPermittedException`
        `UnknownResourceException`
        `AmazonClientException` - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
        `AmazonServiceException` - If an error response is returned by AmazonSimpleWorkflow indicating either a problem with the data in the request, or a server side issue.

    - #### listDomains

          DomainInfos listDomains(ListDomainsRequest listDomainsRequest)
                                  throws AmazonServiceException,
                                         AmazonClientException

      Returns the list of domains registered in the account. The results may be split into multiple pages. To retrieve subsequent pages, make the call again using the nextPageToken returned by the initial call.

      NOTE: This operation is eventually consistent. The results are best effort and may not exactly reflect recent updates and changes.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains. The element must be set to `arn:aws:swf::AccountID:domain/*"` , where ???AccountID" is the account ID, with no dashes.
      - Use an `Action` element to allow or deny permission to call this action.
      - You cannot use an IAM policy to constrain this action's parameters.

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

      パラメータ:
        `listDomainsRequest` - Container for the necessary parameters to execute the ListDomains service method on AmazonSimpleWorkflow.
      戻り値:
        The response from the ListDomains service method, as returned by AmazonSimpleWorkflow.
      例外:
        `OperationNotPermittedException`
        `AmazonClientException` - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
        `AmazonServiceException` - If an error response is returned by AmazonSimpleWorkflow indicating either a problem with the data in the request, or a server side issue.

    - #### requestCancelWorkflowExecution

          void requestCancelWorkflowExecution(RequestCancelWorkflowExecutionRequest requestCancelWorkflowExecutionRequest)
                                              throws AmazonServiceException,
                                                     AmazonClientException

      Records a `WorkflowExecutionCancelRequested` event in the currently running workflow execution identified by the given domain, workflowId, and runId. This logically requests the cancellation of the workflow execution as a whole. It is up to the decider to take appropriate actions when it receives an execution history with this event.

      NOTE: If the runId is not specified, the WorkflowExecutionCancelRequested event is recorded in the history of the current open workflow execution with the specified workflowId in the domain.

      NOTE: Because this action allows the workflow to properly clean up and gracefully close, it should be used instead of TerminateWorkflowExecution when possible.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - You cannot use an IAM policy to constrain this action's parameters.

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

      Returns information about the specified workflow type . This includes configuration settings specified when the type was registered and other information such as creation date, current status, etc.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - Constrain the following parameters by using a `Condition` element with the appropriate keys.
        - `workflowType.name` : String constraint. The key is `swf:workflowType.name` .
        - `workflowType.version` : String constraint. The key is `swf:workflowType.version` .

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

                                           throws AmazonServiceException,
                                                  AmazonClientException

      Used by workers to tell the service that the ActivityTask identified by the `taskToken` was successfully canceled. Additional `details` can be optionally provided using the `details` argument.

      These `details` (if provided) appear in the `ActivityTaskCanceled` event added to the workflow history.

      IMPORTANT: Only use this operation if the canceled flag of a RecordActivityTaskHeartbeat request returns true and if the activity can be safely undone or abandoned.

      A task is considered open from the time that it is scheduled until it is closed. Therefore a task is reported as open while a worker is processing it. A task is closed after it has been specified in a call to RespondActivityTaskCompleted, RespondActivityTaskCanceled, RespondActivityTaskFailed, or the task has timed out .

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - You cannot use an IAM policy to constrain this action's parameters.

                                                   AmazonClientException

      Used by deciders to tell the service that the DecisionTask identified by the `taskToken` has successfully completed. The `decisions` argument specifies the list of decisions made while processing the task.

      A `DecisionTaskCompleted` event is added to the workflow history. The `executionContext` specified is attached to the event in the workflow execution history.

      Access Control

      If an IAM policy grants permission to use `RespondDecisionTaskCompleted` , it can express permissions for the list of decisions in the `decisions` parameter in the same way as for the regular API. This approach maintains a uniform conceptual model and helps keep policies readable. For more information, see Using IAM to Manage Access to Amazon SWF Workflows .

                                                   AmazonClientException

      Used by workers to tell the service that the ActivityTask identified by the `taskToken` completed successfully with a `result` (if provided). The `result` appears in the `ActivityTaskCompleted` event in the workflow history.

      IMPORTANT: If the requested task does not complete successfully, use RespondActivityTaskFailed instead. If the worker finds that the task is canceled through the canceled flag returned by RecordActivityTaskHeartbeat, it should cancel the task, clean up and then call RespondActivityTaskCanceled.

      A task is considered open from the time that it is scheduled until it is closed. Therefore a task is reported as open while a worker is processing it. A task is closed after it has been specified in a call to RespondActivityTaskCompleted, RespondActivityTaskCanceled, RespondActivityTaskFailed, or the task has timed out .

                                                  AmazonClientException

      Used by workers to get an ActivityTask from the specified activity `taskList` . This initiates a long poll, where the service holds the HTTP connection open and responds as soon as a task becomes available. The maximum time the service holds on to the request before responding is 60 seconds. If no task is available within 60 seconds, the poll will return an empty result. An empty result, in this context, means that an ActivityTask is returned, but that the value of taskToken is an empty string. If a task is returned, the worker should use its type to identify and process it correctly.

      IMPORTANT: Workers should set their client side socket timeout to at least 70 seconds (10 seconds higher than the maximum time service may hold the poll request).

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - You cannot use an IAM policy to control domain access for this action. The name of the domain being registered is available as the resource of this action.
      - Use an `Action` element to allow or deny permission to call this action.
      - You cannot use an IAM policy to constrain this action's parameters.

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

                                           AmazonClientException

      Registers a new activity type along with its configuration settings in the specified domain.

      IMPORTANT: A TypeAlreadyExists fault is returned if the type already exists in the domain. You cannot change any configuration settings of the type after its registration, and it must be registered as a new version.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - Constrain the following parameters by using a `Condition` element with the appropriate keys.
        - `defaultTaskList` : String constraint. The key is `swf:defaultTaskList.name` .
        - `name` : String constraint. The key is `swf:name` .
        - `version` : String constraint. The key is `swf:version` .

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

      Returns a list of closed workflow executions in the specified domain that meet the filtering criteria. The results may be split into multiple pages. To retrieve subsequent pages, make the call again using the nextPageToken returned by the initial call.

      NOTE: This operation is eventually consistent. The results are best effort and may not exactly reflect recent updates and changes.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - Constrain the following parameters by using a `Condition` element with the appropriate keys.

                                                         throws AmazonServiceException,
                                                                AmazonClientException

      Used by activity workers to report to the service that the ActivityTask represented by the specified `taskToken` is still making progress. The worker can also (optionally) specify details of the progress, for example percent complete, using the `details` parameter. This action can also be used by the worker as a mechanism to check if cancellation is being requested for the activity task. If a cancellation is being attempted for the specified task, then the boolean `cancelRequested` flag returned by the service is set to `true` .

      This action resets the `taskHeartbeatTimeout` clock. The `taskHeartbeatTimeout` is specified in RegisterActivityType.

      This action does not in itself create an event in the workflow execution history. However, if the task times out, the workflow execution history will contain a `ActivityTaskTimedOut` event that contains the information from the last heartbeat generated by the activity worker.

      NOTE: The taskStartToCloseTimeout of an activity type is the maximum duration of an activity task, regardless of the number of RecordActivityTaskHeartbeat requests received. The taskStartToCloseTimeout is also specified in RegisterActivityType.

      NOTE: This operation is only useful for long-lived activities to report liveliness of the task and to determine if a cancellation is being attempted.

      IMPORTANT: If the cancelRequested flag returns true, a cancellation is being attempted. If the worker can cancel the activity, it should respond with RespondActivityTaskCanceled. Otherwise, it should ignore the cancellation request.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.

    - #### pollForDecisionTask

          DecisionTask pollForDecisionTask(PollForDecisionTaskRequest pollForDecisionTaskRequest)
                                           throws AmazonServiceException,
                                                  AmazonClientException

      Used by deciders to get a DecisionTask from the specified decision `taskList` . A decision task may be returned for any open workflow execution that is using the specified task list. The task includes a paginated view of the history of the workflow execution. The decider should use the workflow type and the history to determine how to properly handle the task.

      This action initiates a long poll, where the service holds the HTTP connection open and responds as soon a task becomes available. If no decision task is available in the specified task list before the timeout of 60 seconds expires, an empty result is returned. An empty result, in this context, means that a DecisionTask is returned, but that the value of taskToken is an empty string.

      IMPORTANT: Deciders should set their client side socket timeout to at least 70 seconds (10 seconds higher than the timeout).

      IMPORTANT: Because the number of workflow history events for a single workflow execution might be very large, the result returned might be split up across a number of pages. To retrieve subsequent pages, make additional calls to PollForDecisionTask using the nextPageToken returned by the initial call. Note that you do not call GetWorkflowExecutionHistory with this nextPageToken. Instead, call PollForDecisionTask again.

      Access Control

      You can use IAM policies to control this action's access to Amazon SWF resources as follows:

      - Use a `Resource` element with the domain name to limit the action to only specified domains.
      - Use an `Action` element to allow or deny permission to call this action.
      - Use a Condition element with the `swf:taskList.name` key to allow the action to access only certain task lists.

      If the caller does not have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails by throwing `OperationNotPermitted` . For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows .

      Used by workers to tell the service that the ActivityTask identified by the `taskToken` has failed with `reason` (if specified). The `reason` and `details` appear in the `ActivityTaskFailed` event added to the workflow history.

      A task is considered open from the time that it is scheduled until it is closed. Therefore a task is reported as open while a worker is processing it. A task is closed after it has been specified in a call to RespondActivityTaskCompleted, RespondActivityTaskCanceled, RespondActivityTaskFailed, or the task has timed out .

      Records a `WorkflowExecutionTerminated` event and forces closure of the workflow execution identified by the given domain, runId, and workflowId. The child policy, registered with the workflow type or specified when starting this execution, is applied to any open child workflow executions of this workflow execution.

      IMPORTANT: If the identified workflow execution was in progress, it is terminated immediately.

      NOTE: If a runId is not specified, then the WorkflowExecutionTerminated event is recorded in the history of the current open workflow with the matching workflowId in the domain.

      NOTE: You should consider using RequestCancelWorkflowExecution action instead because it allows the workflow to gracefully close while TerminateWorkflowExecution does not.

    - #### 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.

      パラメータ:
        `request` - The originally executed request.
      戻り値:
        The response metadata for the specified request, or null if none is available.
