        # Get roles.
        # Get roles in the native realm.
        # The role management APIs are generally the preferred way to manage roles, rather than using file-based role management.
        # The get roles API cannot retrieve roles that are defined in roles files.
        #
        # @option arguments [String, Array<String>] :name The name of the role.
        #  You can specify multiple roles as a comma-separated list.
        #  If you do not specify this parameter, the API returns information about all roles.
        # @option arguments [Boolean] :error_trace When set to `true` Elasticsearch will include the full stack trace of errors
        #  when they occur.
        # @option arguments [String, Array<String>] :filter_path Comma-separated list of filters in dot notation which reduce the response
        #  returned by Elasticsearch.
        # @option arguments [Boolean] :human When set to `true` will return statistics in a format suitable for humans.
        #  For example `"exists_time": "1h"` for humans and
        #  `"exists_time_in_millis": 3600000` for computers. When disabled the human
        #  readable values will be omitted. This makes sense for responses being consumed
        #  only by machines.
        # @option arguments [Boolean] :pretty If set to `true` the returned JSON will be "pretty-formatted". Only use
        #  this option for debugging only.
        # @option arguments [Hash] :headers Custom HTTP headers
        #
