/**
* Client for accessing Amazon SWF. All service calls made using this client are blocking, and will not return until the
* service call completes.
*
* Amazon Simple Workflow Service
*
* The Amazon Simple Workflow Service (Amazon SWF) makes it easy to build applications that use Amazon's cloud to
* coordinate work across distributed components. In Amazon SWF, a task represents a logical unit of work that is
* performed by a component of your workflow. Coordinating tasks in a workflow involves managing intertask dependencies,
* scheduling, and concurrency in accordance with the logical flow of the application.
*
*
* Amazon SWF gives you full control over implementing tasks and coordinating them without worrying about underlying
* complexities such as tracking their progress and maintaining their state.
*
*
* This documentation serves as reference only. For a broader overview of the Amazon SWF programming model, see the Amazon SWF Developer Guide.

/**
*
* 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.
*
* 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. This
* operation is only useful for long-lived activities to report liveliness of the task and to determine if a
* cancellation is being attempted. 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.
* - 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. The associated event attribute's cause parameter will be set to
* OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to

/**
*
* 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.
*
* If the identified workflow execution was in progress, it is terminated immediately.
* 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. You should
* consider using RequestCancelWorkflowExecution action instead because it allows the workflow to gracefully
* close while TerminateWorkflowExecution does not.
*
* 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. The associated event attribute's cause parameter will be set to
* OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to
* Amazon SWF Workflows.
*
*
* @param terminateWorkflowExecutionRequest
* @throws UnknownResourceException
* Returned when the named resource cannot be found with in the scope of this operation (region or domain).
* This could happen if the named resource was never created or is no longer available for this operation.
* @throws OperationNotPermittedException
* Returned when the caller does not have sufficient permissions to invoke the action.
