// Returns information about the specified workflow execution including its type
// and some statistics. 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.
//   - 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 (https://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html)
// in the Amazon SWF Developer Guide.
