public void setEndpoint(String endpoint)
AWSStepFunctions
Callers can pass in just the endpoint (ex: "states.us-east-1.amazonaws.com") or a full URL, including the
protocol (ex: "states.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.

in interface AWSStepFunctions
endpoint
- The endpoint (ex: "states.us-east-1.amazonaws.com") or a full URL, including the protocol (ex:
"states.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.public void setRegion(Region region)
AWSStepFunctions
AWSStepFunctions.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.
setRegion
in interface AWSStepFunctions
region
- The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions)
for accessing a given region. Must not be null and must be a region where the service is available.Region.getRegion(com.amazonaws.regions.Regions)

public CreateActivityResult createActivity(CreateActivityRequest request)
AWSStepFunctions
Creates an activity. An Activity is a task which you write, in any language and hosted on any machine which has
access to AWS Step Functions. Activities must poll Step Functions using the GetActivityTask
and
respond using SendTask*
API calls. This function lets Step Functions know the existence of your
activity and returns an identifier for use in a state machine and when polling from the activity.
createActivity
in interface AWSStepFunctions
public CreateStateMachineResult createStateMachine(CreateStateMachineRequest request)
AWSStepFunctions
Creates a state machine. A state machine consists of a collection of states that can do work (Task
states), determine which states to transition to next (Choice
states), stop an execution with an
error (Fail
states), and so on. State machines are specified using a JSON-based, structured
language.

public DeleteActivityResult deleteActivity(DeleteActivityRequest request)
AWSStepFunctions
Deletes an activity.
deleteActivity
in interface AWSStepFunctions
public DeleteStateMachineResult deleteStateMachine(DeleteStateMachineRequest request)
AWSStepFunctions
Deletes a state machine. This is an asynchronous operation-- it sets the state machine's status to "DELETING" and begins the delete process. Each state machine execution will be deleted the next time it makes a state transition. After all executions have completed or been deleted, the state machine itself will be deleted.

public GetActivityTaskResult getActivityTask(GetActivityTaskRequest request)
AWSStepFunctions
Used by workers to retrieve a task (with the specified activity ARN) which has been scheduled for execution by a
running state machine. This initiates a long poll, where the service holds the HTTP connection open and responds
as soon as a task becomes available (i.e. an execution of a task of this type is needed.) 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 a taskToken
with a null string.
Workers should set their client side socket timeout to at least 65 seconds (5 seconds higher than the maximum time the service may hold the poll request).

public GetExecutionHistoryResult getExecutionHistory(GetExecutionHistoryRequest request)
AWSStepFunctions
Returns the history of the specified execution as a list of events. By default, the results are returned in
ascending order of the timeStamp
of the events. Use the reverseOrder
parameter to get
the latest events first. The results may be split into multiple pages. To retrieve subsequent pages, make the
call again using the nextToken
returned by the previous call.

public ListActivitiesResult listActivities(ListActivitiesRequest request)
AWSStepFunctions
Lists the existing activities. The results may be split into multiple pages. To retrieve subsequent pages, make
the call again using the nextToken
returned by the previous call.

public ListExecutionsResult listExecutions(ListExecutionsRequest request)

Lists the executions of a state machine that meet the filtering criteria. The results may be split into multiple
pages. To retrieve subsequent pages, make the call again using the nextToken
returned by the
previous call.

returned by the previous call.

public SendTaskFailureResult sendTaskFailure(SendTaskFailureRequest request)
AWSStepFunctions
Used by workers to report that the task identified by the taskToken
failed.
sendTaskFailure
in interface AWSStepFunctions
public SendTaskHeartbeatResult sendTaskHeartbeat(SendTaskHeartbeatRequest request)
AWSStepFunctions
Used by workers to report to the service that the task represented by the specified taskToken
is
still making progress. This action resets the Heartbeat
clock. The Heartbeat
threshold
is specified in the state machine's Amazon States Language definition. This action does not in itself create an
event in the execution history. However, if the task times out, the execution history will contain an
ActivityTimedOut
event.
The Timeout
of a task, defined in the state machine's Amazon States Language definition, is its
maximum allowed duration, regardless of the number of SendTaskHeartbeat requests received.
This operation is only useful for long-lived tasks to report the liveliness of the task.

public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
AWSStepFunctions
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.
