--
-- Returns a list of closed workflow executions in the specified domain
-- that meet the filtering criteria. The results may be split into multiple
-- pages. To retrieve subsequent pages, make the call again using the
-- nextPageToken returned by the initial call.
--
-- 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.
-- -   Constrain the following parameters by using a 'Condition' element
--     with the appropriate keys.
--     -   'tagFilter.tag': String constraint. The key is
--         'swf:tagFilter.tag'.
--     -   'typeFilter.name': String constraint. The key is
--         'swf:typeFilter.name'.
--     -   'typeFilter.version': String constraint. The key is
--         'swf:typeFilter.version'.
--
-- If the caller does not 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 will
-- be set to OPERATION_NOT_PERMITTED. For details and example IAM policies,
-- see
-- <http://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html Using IAM to Manage Access to Amazon SWF Workflows>.
--
-- /See:/ <http://docs.aws.amazon.com/amazonswf/latest/apireference/API_ListClosedWorkflowExecutions.html AWS API Reference> for ListClosedWorkflowExecutions.
--
-- This operation returns paginated results.
