This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::SimpleWorkflow::RequestCancelExternalWorkflowExecutionFailedEventAttributes object:

  $service_obj->Method(Att1 => { Cause => $value, ..., WorkflowId => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::SimpleWorkflow::RequestCancelExternalWorkflowExecutionFailedEventAttributes object:

  $result = $service_obj->Method(...);


Provides the details of the RequestCancelExternalWorkflowExecutionFailed event.


REQUIRED Cause => Str

  The cause of the failure. This information is generated by the system
and can be useful for diagnostic purposes.

If cause is set to OPERATION_NOT_PERMITTED, the decision failed because it lacked sufficient permissions. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows ( in the Amazon SWF Developer Guide.

Control => Str

  The data attached to the event that the decider can use in subsequent
workflow tasks. This data isn't sent to the workflow execution.

REQUIRED DecisionTaskCompletedEventId => Int

  The ID of the C<DecisionTaskCompleted> event corresponding to the
decision task that resulted in the
C<RequestCancelExternalWorkflowExecution> decision for this
cancellation request. This information can be useful for diagnosing
problems by tracing back the chain of events leading up to this event.

REQUIRED InitiatedEventId => Int

  The ID of the C<RequestCancelExternalWorkflowExecutionInitiated> event
corresponding to the C<RequestCancelExternalWorkflowExecution> decision
to cancel this external workflow execution. This information can be
useful for diagnosing problems by tracing back the chain of events
leading up to this event.

RunId => Str

  The C<runId> of the external workflow execution.

REQUIRED WorkflowId => Str

  The C<workflowId> of the external workflow to which the cancel request
was to be delivered.
