setEndpoint
Description copied from interface:AmazonSimpleWorkflow
Overrides the default endpoint for this client ("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: "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.
- Specified by:
setEndpoint
in interfaceAmazonSimpleWorkflow
- Parameters:
endpoint
- The endpoint (ex: "swf.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "swf.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
-
setRegion
Description copied from interface:AmazonSimpleWorkflow
An alternative toAmazonSimpleWorkflow.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.
- Specified by:
setRegion
in interfaceAmazonSimpleWorkflow
- Parameters:
region
- The region this client will communicate with. SeeRegion.getRegion(com.amazonaws.regions.Regions)
for accessing a given region. Must not be null and must be a region where the service is available.- See Also:

countClosedWorkflowExecutions
public WorkflowExecutionCount countClosedWorkflowExecutions(CountClosedWorkflowExecutionsRequest request) Description copied from interface:AmazonSimpleWorkflow
Returns the number of closed workflow executions within the given domain that meet the specified filtering criteria.
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

pollForActivityTask
Description copied from interface:AmazonSimpleWorkflow
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.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

pollForDecisionTask
Description copied from interface:AmazonSimpleWorkflow
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 thenextPageToken
returned by the initial call. Note that you do not callGetWorkflowExecutionHistory

recordActivityTaskHeartbeat
Description copied from interface:AmazonSimpleWorkflow
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 thedetails
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 booleancancelRequested
flag returned by the service is set totrue
.This action resets the
taskHeartbeatTimeout
clock. ThetaskHeartbeatTimeout
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. ThetaskStartToCloseTimeout
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 returnstrue
, 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

Registers a new domain.
Access Control
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. 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.

registerWorkflowType
Description copied from interface:AmazonSimpleWorkflow
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.
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

requestCancelWorkflowExecution
Description copied from interface:AmazonSimpleWorkflow
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 is not 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. Access Control
You can use IAM policies to control this action's access to Amazon SWF resources as follows:
- Use a
Resource

respondActivityTaskCanceled
Description copied from interface:AmazonSimpleWorkflow
Used by workers to tell the service that the ActivityTask identified by the
taskToken
was successfully canceled. Additionaldetails
can be optionally provided using thedetails
argument.These
details
(if provided) appear in theActivityTaskCanceled
event added to the workflow history.Only use this operation if the canceled
flag of a RecordActivityTaskHeartbeat request returnstrue
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.

event in the workflow history.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.

respondDecisionTaskCompleted
Description copied from interface:AmazonSimpleWorkflow
Used by deciders to tell the service that the DecisionTask identified by the

has successfully completed. Thedecisions
argument specifies the list of decisions made while processing the task.A
DecisionTaskCompleted
event is added to the workflow history. TheexecutionContext
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 thedecisions
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.

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

getCachedResponseMetadata
Description copied from interface:AmazonSimpleWorkflow
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.
- Specified by:

- Parameters:
request
- The originally executed request.- Returns:
- The response metadata for the specified request, or null if none is available.
