(constructor)

[configuration]

Constructs a new instance of the <code>SWFClient</code> class

config

The resolved configuration of SWFClient class. This is resolved and normalized from the [constructor configuration interface](@aws-sdk/client-swf!SWFClientConfig:Interface).

destroy

Destroy underlying resources, like sockets. It's usually not necessary to do this. However in Node.js, it's best to explicitly shut down the client's agent when it is no longer needed. Otherwise, sockets might stay open for quite a long time before the server terminates them.

SWFClient

<fullname>Amazon Simple Workflow Service</fullname> 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 <a href="https://docs.aws.amazon.com/amazonswf/latest/developerguide/">Amazon SWF Developer Guide</a> .

PollForActivityTaskCommand

Used by workers to get an ActivityTask from the specified activity <code>taskList</code>. 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 returns 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). </important> Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> Constrain the <code>taskList.name</code> parameter by using a <code>Condition</code> element with the <code>swf:taskList.name</code> key to allow the action to access only certain task lists. </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's <code>cause</code> parameter is set to <code>OPERATION_NOT_PERMITTED</code>.

PollForDecisionTaskCommand

Used by deciders to get a DecisionTask from the specified decision <code>taskList</code>. 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> <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 <code>PollForDecisionTask</code> using the <code>nextPageToken</code> returned by the initial call. Note that you do not call <code>GetWorkflowExecutionHistory</code> with this <code>nextPageToken</code>. Instead, call <code>PollForDecisionTask</code> again. </important> Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> Constrain the <code>taskList.name</code> parameter by using a <code>Condition</code> element with the <code>swf:taskList.name</code> key to allow the action to access only certain task lists. </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails.

RecordActivityTaskHeartbeatCommand

Used by activity workers to report to the service that the ActivityTask represented by the specified <code>taskToken</code> is still making progress. The worker can also specify details of the progress, for example percent complete, using the <code>details</code> 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 <code>cancelRequested</code> flag returned by the service is set to <code>true</code>. This action resets the <code>taskHeartbeatTimeout</code> clock. The <code>taskHeartbeatTimeout</code> is specified in RegisterActivityType. This action doesn't in itself create an event in the workflow execution history. However, if the task times out, the workflow execution history contains a <code>ActivityTaskTimedOut</code> event that contains the information from the last heartbeat generated by the activity worker. <note> The <code>taskStartToCloseTimeout</code> of an activity type is the maximum duration of an activity task, regardless of the number of RecordActivityTaskHeartbeat requests received. The <code>taskStartToCloseTimeout</code> is also specified in RegisterActivityType. </note> <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. </note> <important> If the <code>cancelRequested</code> flag returns <code>true</code>, a cancellation is being attempted. If the worker can cancel the activity, it should respond with RespondActivityTaskCanceled. Otherwise, it should ignore the cancellation request. </important> Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> You cannot use an IAM policy to constrain this action's parameters. </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's <code>cause</code> parameter is set to <code>OPERATION_NOT_PERMITTED</code>.

RegisterActivityTypeCommand

Registers a new activity type along with its configuration settings in the specified domain. <important> A <code>TypeAlreadyExists</code> 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. </important> Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> Constrain the following parameters by using a <code>Condition</code> element with the appropriate keys. <ul> <li> <code>defaultTaskList.name</code>: String constraint. The key is <code>swf:defaultTaskList.name</code>. </li> <li> <code>name</code>: String constraint. The key is <code>swf:name</code>. </li> <li> <code>version</code>: String constraint. The key is <code>swf:version</code>. </li> </ul> </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails.

RegisterDomainCommand

Registers a new domain. Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> 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. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> You cannot use an IAM policy to constrain this action's parameters. </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails.

RegisterWorkflowTypeCommand

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 <code>TypeAlreadyExists</code> 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. </important> Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> Constrain the following parameters by using a <code>Condition</code> element with the appropriate keys. <ul> <li> <code>defaultTaskList.name</code>: String constraint.

RequestCancelWorkflowExecutionCommand

Records a <code>WorkflowExecutionCancelRequested</code> 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 isn't specified, the <code>WorkflowExecutionCancelRequested</code> event is recorded in the history of the current open workflow execution with the specified workflowId in the domain. </note> <note> Because this action allows the workflow to properly clean up and gracefully close, it should be used instead of TerminateWorkflowExecution when possible. </note> Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> You cannot use an IAM policy to constrain this action's parameters. </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails.

RespondActivityTaskCanceledCommand

Used by workers to tell the service that the ActivityTask identified by the <code>taskToken</code> was successfully canceled. Additional <code>details</code> can be provided using the <code>details</code> argument. These <code>details</code> (if provided) appear in the <code>ActivityTaskCanceled</code> event added to the workflow history. <important> Only use this operation if the <code>canceled</code> flag of a RecordActivityTaskHeartbeat request returns <code>true</code> and if the activity can be safely undone or abandoned. </important> 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 <a href="https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dg-basic.html#swf-dev-timeout-types">timed out</a>. Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> You cannot use an IAM policy to constrain this action's parameters. </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's <code>cause</code> parameter is set to <code>OPERATION_NOT_PERMITTED</code>.

RespondActivityTaskCompletedCommand

Used by workers to tell the service that the ActivityTask identified by the <code>taskToken</code> completed successfully with a <code>result</code> (if provided). The <code>result</code> appears in the <code>ActivityTaskCompleted</code> event in the workflow history. <important> If the requested task doesn't complete successfully, use RespondActivityTaskFailed instead. If the worker finds that the task is canceled through the <code>canceled</code> flag returned by RecordActivityTaskHeartbeat, it should cancel the task, clean up and then call RespondActivityTaskCanceled. </important> 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 <a href="https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dg-basic.html#swf-dev-timeout-types">timed out</a>. Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> You cannot use an IAM policy to constrain this action's parameters. </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails.

RespondActivityTaskFailedCommand

Used by workers to tell the service that the ActivityTask identified by the <code>taskToken</code> has failed with <code>reason</code> (if specified). The <code>reason</code> and <code>details</code> appear in the <code>ActivityTaskFailed</code> 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 <a href="https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dg-basic.html#swf-dev-timeout-types">timed out</a>. Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> You cannot use an IAM policy to constrain this action's parameters. </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails.

RespondDecisionTaskCompletedCommand

Used by deciders to tell the service that the DecisionTask identified by the <code>taskToken</code> has successfully completed. The <code>decisions</code> argument specifies the list of decisions made while processing the task. A <code>DecisionTaskCompleted</code> event is added to the workflow history. The <code>executionContext</code> specified is attached to the event in the workflow execution history. Access Control If an IAM policy grants permission to use <code>RespondDecisionTaskCompleted</code>, it can express permissions for the list of decisions in the <code>decisions</code> parameter. Each of the decisions has one or more parameters, much like a regular API call. To allow for policies to be as readable as possible, you can express permissions on decisions as if they were actual API calls, including applying conditions to some parameters.

SignalWorkflowExecutionCommand

Records a <code>WorkflowExecutionSignaled</code> 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 isn't specified, then the <code>WorkflowExecutionSignaled</code> event is recorded in the history of the current open workflow with the matching workflowId in the domain. </note> <note> If the specified workflow execution isn't open, this method fails with <code>UnknownResource</code>. </note> Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> You cannot use an IAM policy to constrain this action's parameters. </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails.

TagResourceCommand

Add a tag to a Amazon SWF domain. <note> Amazon SWF supports a maximum of 50 tags per resource. </note>

TerminateWorkflowExecutionCommand

Records a <code>WorkflowExecutionTerminated</code> 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. </important> <note> If a runId isn't specified, then the <code>WorkflowExecutionTerminated</code> event is recorded in the history of the current open workflow with the matching workflowId in the domain. </note> <note> You should consider using RequestCancelWorkflowExecution action instead because it allows the workflow to gracefully close while TerminateWorkflowExecution doesn't. </note> Access Control You can use IAM policies to control this action's access to Amazon SWF resources as follows: <ul> <li> Use a <code>Resource</code> element with the domain name to limit the action to only specified domains. </li> <li> Use an <code>Action</code> element to allow or deny permission to call this action. </li> <li> You cannot use an IAM policy to constrain this action's parameters. </li> </ul> If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails.
