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: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint
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.

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.

public CreateActivityResult createActivity(CreateActivityRequest request)
AWSStepFunctions
Creates an activity. An activity is a task that you write in any programming language and host on any machine
that has access to AWS Step Functions. Activities must poll Step Functions using the GetActivityTask
API action and respond using SendTask*
API actions. 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.
This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.
CreateActivity
is an idempotent API. Subsequent requests won’t create a duplicate resource if it was
already created. CreateActivity
's idempotency check is based on the activity name
. If a
following request has different tags
values, Step Functions will ignore these differences and treat
it as an idempotent request of the previous. In this case, tags
will not be updated, even if they
are different.
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 to which states to transition next (Choice
states), stop an execution with an
error (Fail
states), and so on. State machines are specified using a JSON-based, structured
language. For more information, see Amazon States
Language in the AWS Step Functions User Guide.
This operation is eventually consistent. The results are best effort and may not reflect very recent updates and changes.
CreateStateMachine
is an idempotent API. Subsequent requests won’t create a duplicate resource if it
was already created. CreateStateMachine
's idempotency check is based on the state machine
name
, definition
, type
, LoggingConfiguration
and
TracingConfiguration
. If a following request has a different roleArn
or
tags
, Step Functions will ignore these differences and treat it as an idempotent request of the
previous. In this case, roleArn
and tags
will not be updated, even if they are
different.

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 deletion process.
For EXPRESS
state machines, the deletion will happen eventually (usually less than a minute). Running
executions may emit logs after DeleteStateMachine
API is called.

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 returns 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).
Polling with GetActivityTask
can cause latency in some implementations. See Avoid Latency When Polling
for Activity Tasks in the Step Functions Developer Guide.
getActivityTask
in interface AWSStepFunctions
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.
If nextToken
is returned, there are more results available. The value of nextToken
is a
unique pagination token for each page. Make the call again using the returned token to retrieve the next page.
Keep all other arguments unchanged. Each pagination token expires after 24 hours. Using an expired pagination
token will return an HTTP 400 InvalidToken error.
This API action is not supported by EXPRESS
state machines.

is a
unique pagination token for each page. Make the call again using the returned token to retrieve the next page.
Keep all other arguments unchanged. Each pagination token expires after 24 hours. Using an expired pagination
token will return an HTTP 400 InvalidToken error.

is a
unique pagination token for each page. Make the call again using the returned token to retrieve the next page.
Keep all other arguments unchanged. Each pagination token expires after 24 hours. Using an expired pagination
token will return an HTTP 400 InvalidToken error.

Used by activity workers and task states using the callback pattern to report that the task identified by the taskToken
failed.
sendTaskFailure
in interface AWSStepFunctions
public SendTaskHeartbeatResult sendTaskHeartbeat(SendTaskHeartbeatRequest request)
AWSStepFunctions
Used by activity workers and task states using the callback pattern to report to Step Functions 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 (
HeartbeatSeconds
). This action does not in itself create an event in the execution history. However,
if the task times out, the execution history contains an ActivityTimedOut
entry for activities, or a
TaskTimedOut
entry for for tasks using the job run or
callback pattern.
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. Use
HeartbeatSeconds
to configure the timeout interval for heartbeats.
sendTaskHeartbeat

public SendTaskSuccessResult sendTaskSuccess(SendTaskSuccessRequest request)

Used by activity workers and task states using the callback pattern to report that the task identified by the taskToken
completed successfully.

public StartExecutionResult startExecution(StartExecutionRequest request)
AWSStepFunctions
Starts a state machine execution.
StartExecution
is idempotent. If StartExecution
is called with the same name and input
as a running execution, the call will succeed and return the same response as the original request. If the
execution is closed or if the input is different, it will return a 400 ExecutionAlreadyExists
error.
Names can be reused after 90 days.

public UpdateStateMachineResult updateStateMachine(UpdateStateMachineRequest request)
AWSStepFunctions
Updates an existing state machine by modifying its definition
, roleArn
, or
loggingConfiguration
. Running executions will continue to use the previous definition
and roleArn
. You must include at least one of definition
or roleArn
or you
will receive a MissingRequiredParameter
error.
All StartExecution
calls within a few seconds will use the updated definition
and
roleArn
. Executions started immediately after calling UpdateStateMachine
may use the
previous state machine definition
and roleArn
.
