```
public class AmazonSimpleWorkflowAsyncClient
extends AmazonSimpleWorkflowClient
implements AmazonSimpleWorkflowAsync
```
Asynchronous client for accessing AmazonSimpleWorkflow. All asynchronous calls made using this client are non-blocking. Callers could either process the result and handle the exceptions in the worker thread by providing a callback handler when making the call, or use the returned Future object to check the result of the call in the calling thread. 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.

- RegisterActivityType
- DeprecateActivityType
Workflow Management
- RegisterWorkflowType
- DeprecateWorkflowType
Domain Management
- RegisterDomain

```
    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 .
    Specified by:
    
    deprecateWorkflowTypeAsync in interface AmazonSimpleWorkflowAsync
    
    Parameters:
    deprecateWorkflowTypeRequest - Container for the necessary parameters to execute the DeprecateWorkflowType operation on AmazonSimpleWorkflow.
    
    Returns:
    A Java Future object containing the response from the DeprecateWorkflowType service method, as returned by AmazonSimpleWorkflow.
    
    Throws:
    
    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.

    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 .

    listDomainsAsync in interface AmazonSimpleWorkflowAsync
    
    Parameters:
    listDomainsRequest - Container for the necessary parameters to execute the ListDomains operation on AmazonSimpleWorkflow.
    asyncHandler - Asynchronous callback handler for events in the life-cycle of the request. Users could provide the implementation of the four callback methods in this interface to process the operation result or handle the exception.
    
    Returns:
    A Java Future object containing the response from the ListDomains service method, as returned by AmazonSimpleWorkflow.
    
    Throws:
    
    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.

    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.

    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 .

    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.
    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 .
    Specified by:
    
    respondActivityTaskCanceledAsync in interface AmazonSimpleWorkflowAsync
    
    Parameters:
    respondActivityTaskCanceledRequest - Container for the necessary parameters to execute the RespondActivityTaskCanceled operation on AmazonSimpleWorkflow.
    asyncHandler - Asynchronous callback handler for events in the life-cycle of the request. Users could provide the implementation of the four callback methods in this interface to process the operation result or handle the exception.
    
    Returns:
    A Java Future object containing the response from the RespondActivityTaskCanceled service method, as returned by AmazonSimpleWorkflow.
    
    Throws:
    
    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.

    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).

    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.
      
      tag : String constraint. The key is swf:tagFilter.tag .
      
      typeFilter.name : String constraint. String constraint. The key is swf:typeFilter.name .
      
      typeFilter.version : String constraint. String constraint. The key is swf:typeFilter.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 .

```
    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.

```
    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.
    - 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 .

    recordActivityTaskHeartbeatAsync in interface AmazonSimpleWorkflowAsync
    
    Parameters:
    recordActivityTaskHeartbeatRequest - Container for the necessary parameters to execute the RecordActivityTaskHeartbeat operation on AmazonSimpleWorkflow.
    asyncHandler - Asynchronous callback handler for events in the life-cycle of the request. Users could provide the implementation of the four callback methods in this interface to process the operation result or handle the exception.
    
    Returns:
    A Java Future object containing the response from the RecordActivityTaskHeartbeat service method, as returned by AmazonSimpleWorkflow.
    
    Throws:
    
    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.

    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

    - 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 .

    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.
    
    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 .
    Specified by:
    
    terminateWorkflowExecutionAsync in interface AmazonSimpleWorkflowAsync
    
    Parameters:
    terminateWorkflowExecutionRequest - Container for the necessary parameters to execute the TerminateWorkflowExecution operation on AmazonSimpleWorkflow.
    
    Returns:
    A Java Future object containing the response from the TerminateWorkflowExecution service method, as returned by AmazonSimpleWorkflow.
    
    Throws:
    
    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.

    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.

    - 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 .
    Specified by:
    
    terminateWorkflowExecutionAsync in interface AmazonSimpleWorkflowAsync
    
    Parameters:
    terminateWorkflowExecutionRequest - Container for the necessary parameters to execute the TerminateWorkflowExecution operation on AmazonSimpleWorkflow.
    asyncHandler - Asynchronous callback handler for events in the life-cycle of the request. Users could provide the implementation of the four callback methods in this interface to process the operation result or handle the exception.
    
    Returns:
    A Java Future object containing the response from the TerminateWorkflowExecution service method, as returned by AmazonSimpleWorkflow.
    
    Throws:
    
    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.
