@ThreadSafe @Generated(value="com.amazonaws:aws-java-sdk-code-generator") public class AmazonSimpleWorkflowClient extends AmazonWebServiceClient implements AmazonSimpleWorkflow
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 .

listWorkflowTypes in interface AmazonSimpleWorkflowlistWorkflowTypesRequest - OperationNotPermittedException - Returned when the caller doesn't have sufficient permissions to invoke the action.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.public ActivityTask pollForActivityTask(PollForActivityTaskRequest request)
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 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.
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:
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 taskList.name parameter by using a Condition element with the
swf:taskList.name key to allow the action to access only certain task lists.
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 cause parameter is set to
OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to
Amazon SWF Workflows in the Amazon SWF Developer Guide.
pollForActivityTask in interface AmazonSimpleWorkflowpollForActivityTaskRequest - 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.OperationNotPermittedException - Returned when the caller doesn't have sufficient permissions to invoke the action.LimitExceededException - Returned by any operation if a system imposed limitation has been reached. To address this fault you
should either clean up unused resources or increase the limit by contacting AWS.public DecisionTask pollForDecisionTask(PollForDecisionTaskRequest request)
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.
Deciders should set their client side socket timeout to at least 70 seconds (10 seconds higher than the timeout).
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:

To address this fault you
should either clean up unused resources or increase the limit by contacting AWS.public ActivityTaskStatus recordActivityTaskHeartbeat(RecordActivityTaskHeartbeatRequest 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 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 doesn't in itself create an event in the workflow execution history. However, if the task times out,
the workflow execution history contains 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.

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.
If the runId isn't specified, the WorkflowExecutionCancelRequested event is recorded in the history
of the current open workflow execution with the specified workflowId in the domain.
Because this action allows the workflow to properly clean up and gracefully close, it should be used instead of TerminateWorkflowExecution when possible.

This could happen if the named resource was never created or is no longer available for this operation.OperationNotPermittedException - Returned when the caller doesn't have sufficient permissions to invoke the action.public void respondActivityTaskCanceled(RespondActivityTaskCanceledRequest request)
Used by workers to tell the service that the ActivityTask identified by the taskToken was
successfully canceled. Additional details can be provided using the details argument.
These details (if provided) appear in the ActivityTaskCanceled event added to the
workflow history.
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.

This could happen if the named resource was never created or is no longer available for this operation.OperationNotPermittedException - Returned when the caller doesn't have sufficient permissions to invoke the action.public void respondActivityTaskCompleted(RespondActivityTaskCompletedRequest request)
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.
If the requested task doesn't 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.

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. 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. For
more information, see Using
IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.

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).
If a runId isn't specified, then the WorkflowExecutionSignaled event is recorded in the history of
the current open workflow with the matching workflowId in the domain.

Some workflow execution parameters, such as the decision taskList, must be set to start the
execution. However, these parameters might have been set as defaults when the workflow type was
registered. In this case, you can omit these parameters from the StartWorkflowExecution call
and Amazon SWF uses the values defined in the workflow type.
If these parameters aren't set and no default parameters were defined in the workflow type, this error is displayed.
public void terminateWorkflowExecution(TerminateWorkflowExecutionRequest request)
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 isn't 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 doesn't.
