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).
swf_signal_workflow_execution(domain, workflowId, runId, signalName,
input)[required] The name of the domain containing the workflow execution to signal.
[required] The workflowId of the workflow execution to signal.
The runId of the workflow execution to signal.
[required] The name of the signal. This name must be meaningful to the target workflow.
Data to attach to the WorkflowExecutionSignaled event in the target
workflow execution's history.
svc$signal_workflow_execution( domain = "string", workflowId = "string", runId = "string", signalName = "string", input = "string" )
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.
If the specified workflow execution isn't open, this method fails with
UnknownResource.
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 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.
