-- Gets all detectors or a single detector if a @detectorId@ is specified.
-- This is a paginated API. If you provide a null @maxResults@, this action
-- retrieves a maximum of 10 records per page. If you provide a
-- @maxResults@, the value must be between 5 and 10. To get the next page
-- results, provide the pagination token from the @GetDetectorsResponse@ as
-- part of your request. A null pagination token fetches the records from
-- the beginning.
