-- Gets the inappropriate, unwanted, or offensive content analysis results
-- for a Amazon Rekognition Video analysis started by
-- StartContentModeration. For a list of moderation labels in Amazon
-- Rekognition, see
-- <https://docs.aws.amazon.com/rekognition/latest/dg/moderation.html#moderation-api Using the image and video moderation APIs>.
--
-- Amazon Rekognition Video inappropriate or offensive content detection in
-- a stored video is an asynchronous operation. You start analysis by
-- calling StartContentModeration which returns a job identifier (@JobId@).
-- When analysis finishes, Amazon Rekognition Video publishes a completion
-- status to the Amazon Simple Notification Service topic registered in the
-- initial call to @StartContentModeration@. To get the results of the
-- content analysis, first check that the status value published to the
-- Amazon SNS topic is @SUCCEEDED@. If so, call @GetContentModeration@ and
-- pass the job identifier (@JobId@) from the initial call to
-- @StartContentModeration@.
--
-- For more information, see Working with Stored Videos in the Amazon
-- Rekognition Devlopers Guide.
--
-- @GetContentModeration@ returns detected inappropriate, unwanted, or
-- offensive content moderation labels, and the time they are detected, in
-- an array, @ModerationLabels@, of ContentModerationDetection objects.
--
-- By default, the moderated labels are returned sorted by time, in
-- milliseconds from the start of the video. You can also sort them by
-- moderated label by specifying @NAME@ for the @SortBy@ input parameter.
--
-- Since video analysis can return a large number of results, use the
-- @MaxResults@ parameter to limit the number of labels returned in a
-- single call to @GetContentModeration@. If there are more results than
-- specified in @MaxResults@, the value of @NextToken@ in the operation
-- response contains a pagination token for getting the next set of
-- results. To get the next page of results, call @GetContentModeration@
-- and populate the @NextToken@ request parameter with the value of
-- @NextToken@ returned from the previous call to @GetContentModeration@.
--
-- For more information, see moderating content in the Amazon Rekognition
-- Developer Guide.
